A 1.5-inch spacer changes how your truck or Jeep sits, feels, and handles. It pushes the tires outboard enough to fill the fenders, fix rubbing on suspension parts, and plant the vehicle more squarely through corners. But a wrong bolt pattern, hub bore, or stud thread means the part simply does not bolt on — and a mismatch under load is dangerous. This guide compares six proven sets, each matched to a specific vehicle family, so you know exactly which one fits your year, make, and lug count before you order.

Whether you drive a Wrangler, Silverado, Ram, or an ATV, the right set of 1 1 2 inch spacers tightens your stance and sharpens handling while staying affordable.
Our Picks at a Glance
How To Choose The Best 1 1 2 Inch Spacers
A spacer is a simple piece of metal, but its job is critical. Pick the wrong one, and you get vibrations, loose lug nuts, or even a wheel that separates at speed. Here are the three things to check before you click buy.
Bolt pattern and hub bore are not optional
The bolt pattern (like 5×5 or 6×5.5) must match exactly, but the hole in the center — the hub bore — matters just as much. A hub-centric spacer has a lip that centers on your vehicle’s hub, so the wheel sits perfectly round. Without that lip, the wheel is held by the lug nuts alone and can wobble. Measure your vehicle’s hub bore before ordering.
Forged aluminum versus cast
Forged 6061-T6 aluminum is the gold standard for wheel spacers. It is stronger and more fatigue-resistant than cast aluminum, meaning it can handle the repeated stress of bumps and corners without cracking. Every set on this list uses forged 6061-T6, which is the baseline for safe use on a passenger vehicle.
Stud grade — 10.9 versus 12.9
Grade 12.9 bolts are harder, which sounds better. But harder also means more brittle — if they fail, they snap. Grade 10.9 bolts are slightly softer, so they deform before breaking, giving you a warning sign. Some manufacturers (like dynofit) argue that 10.9 is actually safer for automotive use, while others use 12.9 for maximum tensile strength. Both work correctly when torqued to spec.

In‑Depth Reviews
1. dynofit 1.5″ 5×5 Wheel Spacers for Jeep JK
Our pick — over 4.5★ from 900+ verified ratings; the strongest balance of quality and price.
The JK crowd favorite that proves a 1.5-inch stance upgrade can be dead simple to install.
This set covers every 5x127mm Jeep from the 1999 Grand Cherokee WJ up through the 2018 Wrangler JK — but skips the newer JL. The hub bore of 71.5mm centers the spacer on the factory hub, so you get no wheel shimmy at highway speed. Owners say the ride feels more planted, and the aggressive look is immediate. The package includes four spacers plus open-end lug nuts, and the spacers themselves weigh 16.4 pounds total — each piece feels solid without being a pain to lift into place.
Dynofit uses Grade 10.9 bolts (a strength rating that means they bend instead of snapping under sudden force) because harder 12.9 bolts can crack on impact — a real concern for off-road driving where you hit rocks and ruts. The DACROMAT-treated studs (a corrosion-resistant coating) fight rust, and the anodized black finish holds up under mud and salt. One buyer who installed them on a 2021 Wrangler said they “improved the appearance of the vehicle immensely.” Quality is the top praise, called out by 32 owners. This is the confident pick for any pre-2018 Wrangler or Grand Cherokee owner who wants a proven, durable spacer.
The honest trade-off is that durability opinions split. Most buyers report no issues after thousands of miles, but a few re-torque after the first 500 miles — standard practice for any spacer. If you want a low-maintenance install, torque to the recommended 100 ft-lb (the tightening spec) and check again after a few weeks. Skip this set if you prefer a spacer that never needs re-checking.
Sturdy Jeep fit
- Forged 6061-T6 aluminum is stronger than cast and resists corrosion
- Hub-centric 71.5mm bore keeps vibration away at highway speeds
- Grade 10.9 bolts are chosen for ductility — they bend before snapping
- Four spacers and lug nuts included in one box
Check clearance
- Not compatible with the 2018+ Wrangler JL — check your year carefully
- Durability gets mixed feedback; occasional re-torque after 500 miles is advised
Best for JK: you drive a JK, WJ, WK, or Commander XK and want a proven, well-rated set with stronger-than-average bolts.
Skip if lifted: you need spacers for a JL Wrangler or a Ram — the bolt pattern or hub bore will not line up.
2. Richeer 6×5.5 Wheel Spacers for Silverado
The go-to for full-size GM trucks that demand a 108mm hub-centric fit with 12.9-grade hardware.
Richeer built this set for the 6×139.7mm crowd — every Silverado 1500 from 1999 to 2023, along with Suburbans, Tahoes, Yukons, and even the 2019+ Ram 1500. The hub bore is a generous 108mm, which is notably larger than the 71.5mm bore on the dynofit Jeep spacers. That extra diameter means the spacer lip grabs more of the hub surface for precise centering. The set weighs 16.24 pounds across four pieces, similar to the dynofit but with a higher tensile-strength stud: Grade 12.9, rated at 1000MPa.
Owners consistently praise the machining quality and the fit — one buyer confirmed a perfect fit on a 2014 Silverado 1500 2WD, noting that the hub-centric lip, machining, studs, and threads were all correct. However, the fit quality is a mixed aspect in the broader feedback, with 38 owners mentioning it and opinions split. Some buyers found that several lug nuts spun during tightening or that the spacer introduced a slight vibration between 60 and 80 mph. Proper installation — cleaning the hub face, using the included thread locker, and torquing to 140 ft-lbs — solves this for most, but the inconsistency is the trade-off for the otherwise excellent quality rating (45 positive mentions).
The Richeer set beats the dynofit on raw stud strength if you prefer the harder 12.9 spec, but it does not have the dynofit’s universal praise for fit. For a Silverado owner who follows torque specs to the letter, these spacers deliver a confident stance and long-term durability.
Quality Silverado: The 108mm hub bore is the largest on this list, giving excellent centering on GM trucks, but some owners mention needing extra care during installation to avoid vibration. Torque to 140 ft-lbs and use thread locker for best results.
Top pick GM: you drive a 6-lug Chevy, GMC, or 2019+ Ram and want Grade 12.9 studs at a competitive price.
Skip odd sizes: you want the simplest possible install with zero fitment variance — the dynofit set is more consistently praised for installation ease.
3. Richeer 1.5″ 5×5 Hubcentric for Wrangler JL
The JL-specific spacer that delivers a vibration-free ride with 12.9-grade studs and a 71.5mm bore.
If you drive a 2018-2024 Wrangler JL or a 2022-2024 Grand Cherokee WL, the dynofit set above is not an option — it explicitly excludes those models. Richeer steps in with a 5x127mm spacer that uses 14×1.5 studs (instead of the 1/2″-20 on the JK set) and the same 71.5mm hub bore that matches the Jeep factory hub. Weight is 16 pounds for four spacers, and the machining quality earns 58 positive mentions — the highest quality count of any product on this list. Customers note zero vibrations at 80 mph and a noticeably wider stance that eliminates the tucked-in look.
Several owners emphasize that correct installation is critical. The spacer must be thick enough that the factory studs do not protrude beyond the spacer face — if they do, the wheel cannot seat properly and the lugs can break. For the JL, the 1.5-inch thickness is sufficient, and buyers who torqued to 85-90 ft-lbs and let the thread locker cure for 24 hours had no issues even after 564-mile trips. The ride quality improvement is the fourth most-praised aspect, with 20 owners specifically noting smoother handling and better stability.
One buyer on a Rubicon 4XE called the stance “so much better” with OEM 33-inch tires, adding that there was no change in ride feeling, just a more aggressive look. The durability rating is mixed (32 mentions), but the complaints are sparse — a small number of buyers mention Chinese manufacturing origins as a concern, without reporting actual failures. For JL owners, this is the direct replacement for the dynofit set that does not fit.
Hubcentric JL: Grade 12.9 studs, precision machining, and a wider track without vibrations — if you own a 2018+ Wrangler or Gladiator, this is the spacer to run. Let the thread locker cure fully before full-throttle driving.
JL first choice: you have a JL Wrangler, Gladiator, or newer Grand Cherokee and want Grade 12.9 hardware and proven smooth operation.
Skip older Jeeps: you drive a JK — the dynofit set is a better fit for that generation, both in stud thread and value.
4. KSP 1.5in Wheel Spacers for Ram 1500
The Ram 1500 specialist that solves upper control arm rubbing and centers perfectly with a 77.8mm lip.
KSP designed these specifically for the 2019-2026 Ram 1500 (6×139.7mm bolt pattern) and the 2021-2026 Jeep Grand Wagoneer, with a hub bore of 77.8mm. That is an exact match for the Ram’s front hub, and the hub-centric lip eliminates the high-speed vibration that non-hub-centric spacers can produce. The spacers weigh 19.87 pounds total — the heaviest on the list — reflecting the denser forged 6061-T6 billet and the thicker material needed to handle the Ram’s weight. Grade 10.9 geomet bolts resist corrosion and stripping, and owners consistently praise the fit: 53 mention fit positively, second only to quality at 65.
The most-discussed benefit is appearance: 44 owners call out how the wheels line up with the fender flares, giving a beefy, wide-tire look without aftermarket wheels. One reviewer noted that after driving, the coils settle and the fitment becomes even more flush. Another reported no issues after nearly a year of use, even removing and reinstalling the spacers without thread problems. The only recurring complaint is that the single tube of Loctite included is small for a full set — buyers recommend having extra thread locker on hand.
Compared to the Richeer for Silverado, the KSP for Ram has a tighter fit specification (77.8mm versus 108mm bore) and a stronger owner consensus on fit quality — 53 positive versus 38 mixed for the Richeer. If you drive a 2019+ Ram, this is the spacer that buyers consistently describe as a “solid product” and “exceptional hub-centric fitment.”
Ram dedicated: The 77.8mm bore (the center hole that fits over your hub) matches the factory hub exactly, and owners unanimously praise the fit. Bring your own Loctite tube (thread-locking glue) for confidence.
Ram best match: you have a 2019+ Ram 1500 or Grand Wagoneer and want a spacer that buyers call “exceptional” for fit and appearance.
Skip light trucks: you drive an older Ram with M14x2.0 studs — these use 14×1.5 threads and will not fit pre-2019 models.
5. KSP 6×135 Wheel Spacers for F-150
The F-150 set that solves tire rubbing after a leveling kit and stays tight for 16,000 miles.
KSP’s second entry targets the 6x135mm Ford crowd — 2015-2025 F-150, Expedition, and Navigator. The hub bore is 87.1mm, matching the Ford hub precisely, and the Grade 10.9 geomet bolts are heat-treated to resist stripping. The spacers weigh 19.63 pounds for four pieces, nearly identical to the Ram version. Quality earns 72 positive mentions — the single highest count across all six products — and fit follows closely at 46. Reviewers point out that the spacers fit so snugly on both the hub and the wheel that there is zero play, even before torquing.
The most useful real-world story: one owner paired these 1.5-inch spacers with a 2.5-inch leveling kit on an F-150 and eliminated tire rubbing completely, with solid build quality and precise machining. Another buyer logged 16,000 miles without any loosening or cracks. The appearance gets 42 positive mentions, with the wider stance pushing the wheels from sitting inside the fender to flush with the edge. The spacer surface is laser-engraved with sizing info, a small touch that makes identification after years of use much easier.
Unlike the Richeer set for Silverado, the KSP F-150 spacers show no mixed feedback on fit — every mentioned aspect is positive across quality, fit, appearance, installation, durability, and performance. For a Ford owner who wants a set-and-forget upgrade, this is the most consistently reviewed product on the list.
Ford F-150 fit: Highest quality rating (72 positive mentions), zero mixed feedback on fit, and proven life of 16,000 miles with no issues. Laser-engraved sizing is a welcome bonus.
Ford top pick: you own a 2015+ F-150 or Expedition and want the most positively-reviewed spacer on the list with universal fitment praise.
Skip non-Ford: you have a pre-2015 Ford with M14x2.0 studs — these only fit 14×1.5 thread pitch.
6. GAsupply 1.5″ ATV 4×110 Wheel Spacers
The budget-friendly 4×110 spacer that adds stability to ATVs while staying affordable.
This is the only set on the list designed for 4-lug ATVs and UTVs, with a 4x110mm bolt pattern, 74mm hub bore, and M10x1.25 studs. At 5.1 pounds for two pieces, it is dramatically lighter than the 16.4-pound dynofit set because ATV spacers carry much less weight per corner. The spacers are CNC machined from 6061-T6 aluminum billet and use Grade 12.9 bolts, which is high-grade hardware for a 4-lug application. Fit is the most-praised aspect at 57 mentions, and 27 owners call out the functionality, particularly for solving brake drum clearance issues on Honda Ranchers and improving turning stability for younger riders.
One buyer mentioned that these spacers added stability to a Yamaha Grizzly 700, calling them “a must have for stability and safety.” Another noted that the supplied lug nuts may not grip the studs enough and recommended upgrading to extended shank lug nuts (longer nuts that thread deeper) for a more secure hold. The durability rating is mixed (15 negative mentions) — a small number of owners found the nuts insufficient for heavy use. For a light ATV or trail bike, these spacers work well; for aggressive riding on heavier machines, upgrading the fasteners is cheap insurance.
Compared to the dynofit set for Jeeps, the GAsupply spacers are a completely different weight class and use case. They come in a 2-pack rather than 4-pack , so factor that into your planning if you need all four corners. For the price, they solve the specific problem of ATV tire clearance with well-machined 6061-T6 billet (a strong aircraft-grade aluminum) and Grade 12.9 studs — tough to top for a weekend trail machine.
Lightweight ATV: 5.1 pounds for two spacers, Grade 12.9 studs, and a 74mm bore make this the right pick for 4-lug ATVs. Plan to swap the lug nuts for extended shank versions if you ride hard.
ATV favorite: you have a 4×110 ATV or UTV and need a simple, machined spacer to fix brake clearance or widen the rear track.
Skip highway use: you drive a full-size truck or Jeep — the bolt pattern and bore will not match, and these only come as a 2-pack.
Understanding the Specs
Hub Bore
The center hole that fits over your vehicle’s hub. A hub-centric spacer has a lip that matches the hub bore exactly, so the spacer sits perfectly centered. If the bore is too large, the spacer is lug-centric — held in place only by the lug nuts — which can cause vibration at highway speed. On this list the hub bores range from 71.5mm (Jeep JK and JL) to 108mm (GM trucks), so measure yours before ordering.
Bolt Pattern (PCD)
This is the number of lug holes and the diameter of the circle they form. A 5×5 pattern (also written 5x127mm) has five holes on a 5-inch circle. A 6×5.5 (6×139.7mm) has six holes. The number and circle must match your vehicle exactly — even one millimeter off means the spacer will not bolt on. ATVs often use 4x110mm or 4×110, which is a narrower spacing designed for smaller vehicles.
Stud Grade (10.9 vs 12.9)
This number indicates the tensile strength of the studs. Grade 12.9 can reach 1000MPa, meaning it can handle a higher load before failing. Grade 10.9 is slightly softer but more ductile — it will bend rather than snap, which some manufacturers argue is safer for automotive use because you get a warning before failure. Both are safe when torqued correctly; the key is to not over-torque either grade.
Forged vs Cast Aluminum
Forged 6061-T6 aluminum is heated and pressed under high pressure, aligning the grain structure for higher strength and fatigue resistance. Cast aluminum is poured into a mold, which can leave micro-porosity. Every spacer on this list uses forged 6061-T6, which is the industry standard for safe, load-bearing wheel spacers on passenger vehicles.

Final Thoughts: The Verdict
Across the board, the 1 1 2 inch spacers winner is the dynofit 1.5″ 5×5 for Jeep JK because it combines a forged 6061-T6 build (a strong, lightweight aluminum), intelligently chosen Grade 10.9 ductile bolts, and the strongest owner consensus on quality of any product here — 4.7 stars across 920 ratings is the top-tier score. If you drive a 2019+ Ram, grab the KSP for Ram 1500 for its exact 77.8mm hub bore and 53 positive fit mentions. And for Ford owners wanting a proven set-and-forget upgrade, the KSP for F-150 has the highest quality rating across the whole list (72 positive mentions) and a spotless fit record — 16,000 miles without loosening says everything.
