FLYCLE – Best All-Generation Wheel Spacers for Ram 2500
The FLYCLE 8×6.5 wheel spacer is the only product in this roundup that explicitly addresses the stud pitch change between the pre-2012 and post-2012 Ram 2500/3500 generation by offering two distinct product variants — one configured with the 9/16-18 thread pitch that the older 1994-2011 Ram 2500/3500 uses, and a second variant with the M14x1.5 thread pitch that the 2013-2026 Ram 2500 and 2012-2018 Ram 3500 require. This two-type approach eliminates the most common fitment mistake Ram 2500 owners make when buying wheel spacers: ordering the wrong stud pitch and receiving a product that won’t properly torque to spec on their specific generation of truck. Both variants share the same 2-inch (50.8mm) thickness, the same 8×165.1mm bolt pattern, the same 126.15mm center bore, and the same forged 6061-T6 aluminum construction with grade 12.9 studs, surface anodizing, and CNC automatic processing — only the stud thread pitch changes between them. The grade 12.9 studs are the highest commercially available bolt strength class and provide the tensile strength margin that a 2-inch spacer on a heavy-duty Ram 2500 platform with significant towing and payload loads actually demands. The surface anodizing and heat treatment combination enhances both corrosion resistance and material hardness, extending the service life of the spacer across the sustained thermal and mechanical cycling of regular heavy-duty use. FLYCLE’s ongoing post-purchase support commitment means owners with fitment questions have a resolution path available after the sale.
- Two types cover old and new Ram 2500
- Grade 12.9 highest strength class studs
- Covers 1994-2026 Ram 2500 broadest range
- CNC anodized forged 6061-T6 construction
- Post-purchase support team accessible always
- Must select correct type before purchasing
- Excludes 2019-2026 Ram 3500 DRW models
Expert Recommendation
The FLYCLE is the pick for Ram 2500 owners who want a single trusted brand covering every generation from 1994 to 2026 with the correct stud pitch for their specific year. Two variants, grade 12.9 studs, and forged aluminum construction make it the most generation-aware and complete wheel spacer solution for the Ram 2500 platform.
Bronson Built – Best USA-Made Wheel Spacers for Ram 2500 and 3500
The Bronson Built is the most versatile and configuration-flexible wheel spacer in this roundup for the Ram 2500 and 3500 8×6.5 platform, offering a thickness range of 1.5 inches through 4 inches — a span that covers everything from mild stance correction to serious wide-body fitment in a single product line. That 1.5 to 4-inch thickness range is the standout feature that no other spacer in this comparison offers, giving Ram 2500 owners precise control over their final wheel offset rather than being limited to whichever thickness a specific product was manufactured in. The OEM-exact 121.3mm center bore is machined to the standard specification of the Ram 8×6.5 platform, providing a hubcentric fit that centers the spacer directly on the factory hub flange for vibration-free, precision-aligned installation across both front and rear axles. The stud thread pitch is selectable at purchase — 14×1.5 or 9/16-18 OEM RAM spec — which means the Bronson Built fits the same broad range of Dodge and Ram D250/D350 through current 2500/3500 HD trucks that the FLYCLE covers, without requiring the buyer to choose a pre-configured variant. USA-made hub-centric construction speaks directly to the owner who wants the confidence of knowing their heavy-duty truck’s wheel spacer was machined domestically to a standard they can verify. Critical note: front and rear spacers are not interchangeable — select the correct axle position when ordering. No returns or exchanges once installed.
- Widest thickness range 1.5 to 4 inches
- USA-made OEM 121.3mm precise center bore
- Selectable stud pitch 14Ă—1.5 or 9/16-18
- Covers all Dodge Ram 8Ă—6.5 platform trucks
- Front and rear specific configurations available
- Front and rear not interchangeable must select
- No returns or exchanges once installed
Expert Recommendation
The Bronson Built is the pick for Ram 2500/3500 owners who want USA-made precision, OEM-exact 121.3mm bore, and the widest thickness selection in this comparison — from a conservative 1.5-inch correction to a full 4-inch wide-body fitment. If you know exactly what offset your build demands, Bronson Built delivers it.
Rough Country – Best Value Wheel Spacers for Ram 2500 1994-2011
The Rough Country 2-inch wheel spacers for the 1994-2011 Ram 2500/3500 are the most visually distinctive and brand-recognized option in this roundup — the anodized red finish is the signature Rough Country aesthetic that immediately identifies the brand in the engine bay and wheel well, and it’s the only spacer in this comparison that offers a color treatment beyond black or silver. For Ram 2500 owners who are already running other Rough Country components and want a unified visual identity throughout their suspension and wheel hardware, the red anodized spacers are the natural pairing. The 6061-T6 aluminum construction provides the structural integrity and corrosion resistance that a heavy-duty truck wheel spacer requires, and the preinstalled studs eliminate the separate stud sourcing and installation step that some competitors require. The spacers are sold in pairs, covering both wheels on a single axle in a single purchase. Hub-centric design is noted as not available for all models — verify your specific Ram 2500 year and configuration before purchasing to confirm whether the hub-centric spec applies to your truck. The 9/16-inch stud fitment spec means this product is configured for the older-generation Ram 2500/3500 through 2011 — owners of post-2012 Ram 2500 trucks should verify stud pitch compatibility before ordering. No DRW compatibility. Backed by Rough Country’s established brand support infrastructure.
- Anodized red finish distinctive visual identity
- Preinstalled studs no separate sourcing needed
- Rough Country brand established reputation
- 6061-T6 aluminum corrosion resistant construction
- Sold in pairs axle coverage included
- Hub-centric not available for all models
- 9/16-inch stud only, not for post-2012 Ram
Expert Recommendation
The Rough Country is the pick for 1994-2011 Ram 2500 owners who want a brand-trusted, red anodized spacer with preinstalled studs that matches the rest of their Rough Country build. The visual identity, established brand support, and straightforward bolt-on installation make it the most recognizable value choice for the older Ram 2500 platform.
Mishimoto Borne Off-Road – Best Premium Wheel Spacers for Ram 2500 Cummins
The Mishimoto Borne Off-Road wheel spacers are the premium-tier option in this roundup, bringing together grade 12.9 steel studs, forged 6061-T6 aluminum, a choice of black or blue anodized finish, a direct fit for the 2019+ RAM 6.7L Cummins, and the Mishimoto Lifetime Warranty — the only lifetime warranty in this entire comparison. For Ram 2500 Cummins owners who build their trucks as serious tools and want the peace of mind that comes from a brand with decades of engineering credibility and a warranty that never expires, the Mishimoto Borne Off-Road spacers are the unambiguous premium choice. The grade 12.9 steel studs are the same highest-class fastener specification found in the FLYCLE, but the Mishimoto adds all lug nuts in the kit — a complete hardware package that requires no separate hardware sourcing to install. The hub-centric design functions as a direct extension of the axle hub rather than simply filling the gap between hub and wheel, which reduces the load carried by the studs and hardware during dynamic driving — a genuine engineering advantage on a platform that regularly tows at or near its maximum rated capacity. The anodized finish is available in black or blue, giving Ram 2500 owners a color choice that no other spacer in this comparison offers beyond Rough Country’s red. Compatible with any vehicle running the 8×165.1mm bolt pattern, M14x1.5 studs, and 121.3mm center bore — which covers the full 2019+ Ram 2500/3500 HD platform alongside the 6.7L Cummins direct fit.

KSP – Best Overall Wheel Spacers for Ram 1500 2019+
The KSP wheel spacers for the 2019+ Ram 1500 combine the engineering spec that matters most — hubcentric fitment with lips — with the grade 10.9 geomet bolt hardware that separates a spacer you trust at highway speed from one you merely hope holds. The hubcentric-with-lips design is the key safety engineering detail: the lip interface matches the Ram 1500’s hub bore geometry precisely, centering the spacer on the hub and eliminating the micro-movement that non-hubcentric spacers allow at high speed. That movement is what causes vibration, and eliminating it is why this design outperforms non-hubcentric alternatives in real-world highway driving. The grade 10.9 geomet-coated bolts deliver the mechanical strength and corrosion resistance that a load-bearing fastener in a wheel assembly demands — geomet coating provides exceptional rust resistance in salt, moisture, and debris environments where Ram 1500 owners frequently operate. The forged 6061-T6 aircraft-grade aluminum construction provides a strength-to-weight ratio that cast alternatives cannot match, keeping unsprung weight to a minimum while delivering structural integrity under the dynamic loads of towing, hauling, and off-road use. The KSP spacers also fit the 2021+ Jeep Grand Wagoneer — a useful compatibility detail for households running both platforms with the same bolt pattern. Note that these spacers are spec’d for 77.8mm center bore vehicles specifically, and if your Ram 1500’s factory bolts extend beyond 38mm, trimming will be required before installation. Backed by a 30-day refund and 12-month free parts replacement warranty.
- Hubcentric lips eliminate high-speed vibration
- Grade 10.9 geomet bolts corrosion resistant
- Forged 6061-T6 stronger than cast alternatives
- Also fits 2021+ Jeep Grand Wagoneer
- 30-day refund 12-month parts replacement warranty
- 77.8mm bore only, verify before purchasing
- Bolts over 38mm may require trimming
Expert Recommendation
The KSP is the best all-around wheel spacer for 2019+ Ram 1500 owners who want hubcentric precision, grade 10.9 geomet bolt hardware, and multi-platform compatibility backed by a genuine parts replacement warranty. If vibration-free high-speed driving matters as much as the aggressive stance, this is the spacer to reach for first.
Nilight – Best Value Hubcentric Wheel Spacers for Ram 1500
The Nilight 1.5-inch hubcentric wheel spacers for the 2019-2024 Ram 1500 deliver a precisely machined, anodized aluminum solution at a price point that makes a full four-wheel installation accessible without the budget anxiety that premium-tier alternatives can introduce. The CNC automatic processing is the manufacturing step that makes the difference between a spacer that fits cleanly and one that requires shimming, forcing, or returns — CNC machining holds tolerances tight enough to ensure the spacer face makes full, even contact with the Ram 1500’s hub flange, which is the foundation of safe and vibration-free installation. The anodic oxidation surface treatment is a step beyond standard powder coating: anodizing is an electrochemical process that integrates the protective layer into the aluminum surface rather than applying it on top, delivering enhanced hardness and corrosion resistance that holds up significantly better in the mud, salt, and moisture environments that Ram 1500 owners encounter in daily use. The practical results of the Nilight spacers are the ones Ram 1500 owners specifically ask about — solving brake caliper clearance issues when running aftermarket wheels, eliminating the wheel-well rub that can develop with leveling kits and larger tires, and improving the cornering stability that comes from a wider track width. The 1.5-inch spacing hits the sweet spot for most Ram 1500 builds: enough to achieve the aggressive flush fitment that transformed-stance owners want, without pushing wheel offset so far that handling dynamics are compromised. Four spacers per kit for complete vehicle coverage.
- CNC machined precise hub-to-spacer contact
- Anodic oxidation superior hardness and rust resistance
- Solves caliper clearance and wheel well rub
- Four-piece kit full vehicle coverage included
- 1.5-inch sweet spot stance without handling compromise
- 2019-2024 coverage only, not 2025-2026
- Verify exact bore and bolt spec before purchase
Expert Recommendation
The Nilight is the best value pick for 2019-2024 Ram 1500 owners who want CNC-machined hubcentric spacers with anodized surface protection at an accessible price. Four spacers in the kit, precise machining, and real-world solutions for caliper clearance and wheel well rub make it the most practical everyday-use spacer in this roundup.
FLYCLE – Best 2-Inch Wheel Spacers for Ram 1500 2019-2026
The FLYCLE 2-inch wheel spacers are the maximum-stance solution for 2019-2026 Ram 1500 owners who want the most aggressive wheel offset available in this roundup — a full 50mm of additional track width that fundamentally transforms the visual profile of the truck and opens up fitment for significantly wider and larger tire packages. The 2-inch spacing is the choice for Ram 1500 owners running leveling kits with oversized tires who need the additional width to clear the front struts and control arms cleanly, or for owners who simply want the wheels to sit flush with or slightly proud of the fender line for the widebody truck look that the Ram 1500’s styling supports exceptionally well. The exclusive grade 12.9 screws are the standout fastener specification in this comparison — grade 12.9 represents the highest commercially available bolt strength grade, with a tensile strength that exceeds the grade 10.9 hardware used by the KSP and Nilight options. For a 2-inch spacer working under the higher offset loads of a full Ram 1500 payload and towing application, the stronger fastener grade provides an additional margin of safety that matters. The forged 6061-T6 aluminum construction with CNC processing ensures tight hub contact, and the hubcentric design centers the spacer on the factory bore to prevent the vibration that non-hubcentric 2-inch spacers can develop. Covers the full 2019-2026 Ram 1500 production range — the widest model year coverage in this roundup. Kit includes four spacers, two thread lockers, and a user manual.
- 2-inch maximum stance and tire clearance
- Grade 12.9 highest strength bolt grade available
- Widest fitment 2019-2026 full Ram 1500 range

KSP – Best Overall Wheel Spacers for Ram 1500 Classic Body
The KSP 1.5-inch wheel spacers for the 2012-2018 Ram 1500 and Classic body offer the most complete combination of material quality, hardware certification, and owner support in this roundup for the 5-lug Ram platform. The forged 6061-T6 aluminum construction is meaningfully stronger and lighter than cast aluminum alternatives — a distinction that matters under the dynamic loading of a half-ton truck’s suspension cycles, where the spacer is continuously managing the forces of acceleration, braking, and cornering at combined vehicle and payload weights that stress lesser materials over time. The grade 10.9 geomet studs are SGS test approved — a third-party certification that backs up the hardware strength claim with documented verification rather than a manufacturer spec sheet figure. Geomet coating provides corrosion resistance performance well above zinc plating, which is the default treatment on non-certified studs. The black anodized surface treatment on the spacer body protects the aluminum against road salt, moisture, and the thermal cycling that truck wheel assemblies experience through seasonal temperature swings — a surface protection upgrade that extends the visual and structural life of the spacer across years of use. Thread locker is included in the kit for additional fastener security during the break-in period and beyond. The 30-day refund and 12-month free replacement warranty is backed by KSP’s commitment to customer resolution, making this the most warranty-confident purchase in this comparison. Note that the 2019+ Ram 1500 Classic fitment is for 5-lug vehicles only — verify your specific configuration before purchasing.
- Grade 10.9 geomet studs SGS test certified
- Black anodized body superior corrosion protection
- Forged 6061-T6 stronger lighter than cast
- Thread locker included extra fastener security
- 30-day refund 12-month free replacement warranty
- 5-lug Classic only, verify configuration before purchase
- 1.5-inch only, no larger spacing option here
Expert Recommendation
The KSP is the best all-around pick for 2012-2018 Ram 1500 and Classic body owners who want SGS-certified grade 10.9 hardware, black anodized corrosion protection, and a genuine 12-month replacement warranty. The combination of third-party certified studs and a real parts guarantee makes it the most trustworthy spacer investment in this comparison.
Nilight – Best Value Wheel Spacers for Ram 1500 2012-2018
The Nilight 1.5-inch hubcentric wheel spacers for the 2012-2018 Ram 1500 and Classic platform deliver CNC-machined precision with anodized surface protection at a price point that makes a complete four-wheel installation accessible without a significant budget commitment. CNC automatic processing is the manufacturing step that separates a spacer that installs cleanly from one that requires adjustment — the tightly held tolerances of CNC machining ensure the spacer face makes full, even contact with the Ram’s hub flange, which is the mechanical foundation for vibration-free driving and secure long-term installation. The anodic oxidation surface treatment integrates the protective layer directly into the aluminum structure rather than applying it over the surface, producing a hardness improvement and corrosion resistance that outlasts powder-coated alternatives under road salt, moisture, and seasonal temperature variation. The practical case for the Nilight spacers for 2012-2018 Ram 1500 owners is the same set of problems that most owners installing these spacers are trying to solve: brake caliper clearance when moving to aftermarket wheels, wheel well rub that develops when combining a leveling kit with factory or oversized tires, and the handling improvement that comes from a wider track width increasing cornering stability. At 1.5 inches, the spacing delivers a meaningful visual and functional improvement without pushing wheel geometry into territory where steering feel and suspension dynamics become noticeably compromised. Four spacers per kit cover all four corners of the truck in a single purchase.
- CNC machined tight hub-to-spacer contact tolerance
- Anodic oxidation integrated hardness protection layer
- Solves caliper clearance and wheel well rub
- Four-piece kit all four corners covered
- Best value 1.5-inch option in roundup
- No third-party hardware certification listed
- 5-lug Classic only, verify before purchasing
Expert Recommendation
The Nilight is the best value wheel spacer for 2012-2018 Ram 1500 and Classic owners who want CNC precision and anodized surface protection at an accessible price. Four spacers in the kit, clean machined fitment, and real caliper and wheel well clearance results make it the most practical budget pick for the Classic Ram platform.
FLYCLE – Best 2-Inch Wheel Spacers for Ram 1500 Classic Body
The FLYCLE 2-inch wheel spacers for the 2012-2018 Ram 1500 and Classic body are the maximum-stance option in this comparison, delivering a full 50.8mm of additional track width that pushes the Classic Ram’s wheel stance to its most aggressive expression. For Ram 1500 owners running leveling kits or suspension lifts with wider tires, the 2-inch spacing provides the additional clearance that makes oversized fitments practical rather than marginal — the extra track width moves the wheel far enough outward to prevent contact between the tire sidewall and the strut, shock body, or inner fender liner that 1.5-inch spacers sometimes leave too close for comfort with larger tire sizes. The grade 12.9 studs are the standout hardware specification in this roundup — the highest commercially available bolt strength class, with tensile strength that exceeds the grade 10.9 hardware of the KSP and Nilight options by a meaningful margin. For a 2-inch spacer operating under the higher offset loads and leverage forces that larger spacing creates, the stronger stud grade provides an engineering safety margin that matters in towing, hauling, and off-road applications. The 108mm center bore is notably more accommodating than the 77.8mm spec of the 1.5-inch options in this roundup, fitting vehicles with center bores up to 108mm and expanding compatibility for owners whose specific hub configuration may not suit the tighter bore spacers. Kit includes four spacers, two thread lockers, and a user manual. Note that this product fits 5-lug Classic body Ram 1500 only.
- 2-inch maximum stance and tire clearance
- Grade 12.9 highest stud strength class available
- 108mm center bore wider hub compatibility range
- Four spacers plus two thread lockers kit
- CNC anodized forged 6061-T6 construction
- 2-inch offset verify fender clearance before installing
- 5-lug Classic only, not for 2019+ DT platform
Expert Recommendation
The FLYCLE 2-inch is the pick for Classic Ram 1500 owners who want maximum stance, the widest center bore compatibility, and grade 12.9 studs that deliver the highest bolt strength available in this category. For lifted builds running oversized tires where 1.5 inches simply isn’t enough clearance, this is the spacer that finishes the job.
Best Wheel Spacers for RAM 3500 Dually
Dually wheel spacers are a specialized category — the wrong spec on an 8-lug platform carrying serious payload is not a situation anyone wants to find themselves in on the highway. These three options cover the Ram 3500 Dually across multiple configurations, from the 2019+ 8x200mm platform to older 8×165/170/180mm bolt patterns, all in forged or billet aerospace aluminum built to handle the demands of a one-ton work truck.

VLAOSCHI – Best Overall Wheel Spacers for RAM 3500 Dually
The VLAOSCHI dually wheel spacers deliver the broadest brand compatibility of any spacer in this roundup for the modern 8×200 and 8x210mm dually platform — covering the 2019-2023 RAM 3500 Dually alongside the F350 Dually and Silverado/Sierra 3500HD Dually in a single product. That multi-platform coverage is a practical advantage for fleet owners, shops, and households running multiple one-ton dually trucks across brands where a single trusted spacer spec covers the inventory. The forged 6061-T6 aerospace aluminum construction is the material choice that makes sense on a platform carrying 3,500-plus pound payload ratings — forged aluminum’s grain structure is aligned during the manufacturing process, producing a part with meaningfully superior strength and fatigue resistance compared to cast aluminum alternatives that are more common at budget price points. The black anodic oxidation surface treatment provides corrosion resistance that holds up through the sustained exposure to road salt, moisture, and debris that commercial and heavy-use dually operators experience across high annual mileage. At 1/2-inch (12mm) thickness, the VLAOSCHI delivers a meaningful stance improvement without pushing the dually’s already-wide wheel geometry into territory that creates clearance problems with running boards, fender flares, or dually fender liners. Installation is bolt-on with no special tools required, and VLAOSCHI backs every product with a two-year warranty against defects in material and workmanship. Important: does not fit 8×170 or 8×180 bolt patterns — verify your specific platform before ordering.
- Covers RAM F350 and Silverado/Sierra dually
- Forged 6061-T6 superior strength vs cast
- Black anodized corrosion resistance long-term
- 2-year warranty material and workmanship defects
- Bolt-on no special tools required installation
- Does not fit 8Ă—170 or 8Ă—180 patterns
- No returns once spacers have been installed
Expert Recommendation
The VLAOSCHI is the pick for 2019-2023 RAM 3500 Dually owners who also run F350 or GM dually trucks and want one trusted spacer spec across multiple platforms. Forged aerospace aluminum, black anodized protection, and a 2-year warranty make it the most complete and versatile dually spacer in this comparison.
Bronson Built – Best USA-Made Wheel Spacers for RAM 3500 Dually 2019+
The Bronson Built dually wheel spacer is the most Ram 3500-specific and most American-made option in this roundup — CNC precision machined on USA-made HAAS machines from solid extruded USA aerospace grade 6061 T-6 billet aluminum, with an OEM-exact 142mm center bore spec matched directly to the 2019+ Ram 3500 Dually factory hub dimensions. On a one-ton dually platform that routinely hauls gooseneck trailers and maximum payload loads, the provenance of the material and the precision of the machining are not just marketing points — they are the factors that determine whether a wheel spacer performs safely across hundreds of thousands of miles of commercial duty cycles. The 142mm center bore is the design detail that separates the Bronson Built from the VLAOSCHI’s 154mm bore: the Bronson Built is spec’d to the exact OEM RAM hub bore rather than a generic clearance bore, producing a hubcentric fit that centers the spacer with zero slop against the factory hub flange. This precision matters most under the sustained torsional and lateral loading of a loaded dually during cornering and braking. The versatility across front, rear, and between inner/outer dually wheel positions is a practical advantage for owners who want to run spacers at all three positions for specific stance or clearance requirements — a configuration flexibility that most dually spacers don’t explicitly address. At 1/2-inch (13mm), the Bronson Built stays conservative enough to preserve adequate wheel stud thread engagement. Important: measure wheel stud engagement before running thicker spacers on any dually application.
- USA-made HAAS CNC machined precision
- Solid extruded USA aerospace billet aluminum
- 142mm OEM RAM exact hub bore match
- Fits front rear and between dually positions
- Ram 3500 Dually 2019+ specific engineered design
- 2019+ Ram only, no older platform coverage
- Verify stud thread engagement before thicker spacers
Expert Recommendation
The Bronson Built is the pick for 2019+ RAM 3500 Dually owners who want USA-made billet aluminum, HAAS CNC precision, and an OEM-exact 142mm center bore that no generic clearance-bore spacer can match. For a one-ton dually carrying real commercial loads, this is the spacer built to the standard the platform demands.
KSP – Best Wheel Spacers for Older RAM 2500/3500 and Heavy Duty Trucks
The KSP universal 8-lug wheel spacer is the option for Ram 2500 and 3500 owners running the older 8×165.1mm, 8x170mm, or 8x180mm bolt pattern configurations — the platforms that the VLAOSCHI and Bronson Built specifically do not cover. This is an important distinction: while the 2019+ Ram 3500 Dually moved to the 8x200mm bolt pattern, the 1994-2018 Ram 2500/3500 used the 8×165.1mm pattern, and those trucks represent a massive installed base of owners who need a heavy-duty wheel spacer that actually fits their platform. The KSP’s coverage of three separate 8-lug bolt patterns in a single product — 8×165.1, 8×170, and 8x180mm — makes it the most versatile spacer in the roundup for pre-2019 heavy-duty truck owners, covering not just the older Ram 2500/3500 but also the F-250/F-350, Silverado 2500HD/3500HD, and a broad range of GM commercial vehicles across decades of production. The CNC machining from 6061-T6 aluminum billet produces the dimensional accuracy that eliminates vibration — a critical requirement on a platform that may be towing 30,000-plus pound trailer combinations where any wheel assembly imbalance becomes immediately apparent. The silver anodized surface provides corrosion resistance appropriate for the sustained outdoor and work-site exposure these trucks face. Thread locker is included for additional fastener security on the initial installation. Backed by KSP’s 30-day refund and 12-month free replacement warranty. Note: does not fit the 2019+ Ram 3500 Dually 8x200mm platform — use the VLAOSCHI or Bronson Built for that application.
- Covers three 8-lug patterns 165 170 180mm
- Widest heavy-duty vehicle compatibility in roundup
- 6061-T6 billet CNC machined silver anodized
- Thread locker included extra fastener security
- 30-day refund 12-month free replacement warranty
- Does not fit 2019+ Ram 3500 Dually 8x200mm
- Universal fit less precise than platform-specific options

The KSP is the pick for 1994-2018 Ram 2500/3500 owners and heavy-duty truck operators running the older 8×165, 8×170, or 8x180mm bolt patterns. The three-pattern compatibility, CNC billet construction, and KSP’s 12-month replacement warranty make it the most practical and versatile spacer for the pre-2019 heavy-duty Ram and GM platform.
The Final Words
The best wheel spacers for Dodge Ram are not always the thickest or most expensive—they are the ones that match your truck’s setup and driving style. A quality spacer kit can sharpen the stance, unlock better wheel fitment, and add confidence to your build. Pick carefully, install properly, and let your Ram sit the way it was meant to.
