Your truck’s bolt pattern decides everything when you shop for rim spacers. Miss that number and the part won’t seat on the hub, even if it’s machined perfectly. Here are nine popular Amazon sets, sorted into true hub-centric fits (spacers that center on the hub) versus lug-centric compromises (spacers that center on the wheel lugs), so you know which one bolts onto your Silverado, F-150, or Ram 1500 without surprises.
I’m Mo Maruf — the founder and writer behind GoCarLife. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Every spacer here is judged on fitment, build material, and real owner experience, so you can find the right truck rim spacers for your exact year and model with total confidence.
Our Picks at a Glance
How To Choose The Best Truck Rim Spacers
Before you pick a thickness or a finish, you need to confirm three compatibility numbers that are unique to your truck. Get these right and installation is a straightforward afternoon job; get them wrong and the wheel won’t sit flush, which can cause wobble and vibration at highway speed.
Bolt Pattern and Hub Bore Are Non-Negotiable
The bolt pattern (written like 6×5.5 or 6×135) tells you how many lugs you have and the diameter of the circle they sit on. The hub bore is the center hole that centers the spacer on your axle. A spacer with the wrong hub bore is a loose fit that relies entirely on the lug nuts for support, which is exactly how vibration and stud stress start.
Hub-Centric Beats Lug-Centric for Daily Driving
A hub-centric spacer’s lip matches the hub bore, transferring weight through the axle center instead of the lug studs. Lug-centric spacers (or those listed as “not hubcentric”) are cheaper but put more stress on the hardware. If you tow or drive long highway miles, the extra few dollars for a hub-centric fit is worth it.
Material and Stud Grade Set the Safety Ceiling
Almost every quality spacer is machined from 6061-T6 aluminum, either forged or billet. The studs are the real weak point, though: look for 10.9-grade hardware, which is heat-treated and resists stretching or snapping under load. This is a safety-critical part, so don’t buy on price alone.

In-Depth Reviews
1. Rough Country 2″ Wheel Spacer
Our pick — over 4.5★ from 750+ verified ratings; the strongest balance of quality and price.
The proven crowd favorite for GM owners who want the widest stance without touching the suspension.
If your Silverado or Sierra feels tucked-in at the rear after a lift, this 2-inch set is the standard fix. It’s machined from 6061-T6 aluminum with preinstalled wheel studs, so you bolt it on, torque it down, and match your rear track width to the front in about 20 minutes with power tools and a good jack. That’s not a guess; it’s exactly what buyers report in their install notes.
The 6×5.5 bolt pattern, 3.08-inch center bore, and M14x1.5 thread pitch are the exact specs GM 1500 trucks use, which is why fitment is rarely an issue here. Owners have put these through a 45 mph off-road jump without bending a stud, and the durability record backs up Rough Country’s Limited Lifetime replacement warranty.
What wins people over is the quality — it’s the most-mentioned point in the owner feedback — and the appearance follows close behind; the aggressive offset is exactly why people buy a 2-inch spacer.
Why Owners Love It
- Fast, no-drill install with preinstalled studs and corrosion-resistant build.
- Survives rough trail use and off-road jumps without stud failure.
- Boosts the aggressive muscle-car stance owners want.
Watch For
- This exact 2-inch width can cause slight wheel-well rub on stock suspension.
- You’ll want to retorque the lug nuts after about 100 miles of driving.
Grab it if: you drive a GM 1500 and want the maximum 2-inch track widening with a brand backed by a lifetime replacement warranty.
Think twice if: your truck is on factory suspension and you can’t tolerate any fender rub; a 1.5-inch set may clear better.
2. EVIL ENERGY 6×5.5 1-Inch Spacers
A featherweight 1-inch correction that gives Chevy and GMC owners a smoother ride on rough ground.
At just 6.12 pounds, this set is a fraction of the weight of the 2-inch F-150 spacers on this list — a 2.9x gap — yet it’s cut from 6061-T6 aircraft-grade aluminum billet with 10.9-grade geomet bolts. The lightness matters when you’re correcting a minor backspacing issue rather than chasing a massive stance.
The spec sheet is broad: it covers Silverado 1500, Express vans, Suburban, Tahoe, Sierra, and Yukon across nearly two decades of model years, all on the 6×139.7 mm pattern with a 108 mm hub bore. It’s also labeled “Not Hubcentric,” which means the wheel centers on the lugs rather than a lip, so you’ll want professional balancing after install to keep vibration away.
Owners mention the fit is flush on both hub and wheel with stock lug bolts, and one owner summed it up: “So far so good. I installed them a week ago and they fit perfect.” The included hardware and thread lock make installation straightforward, and the anodized black finish resists corrosion.
Light and Capable: This 1-inch (25.4 mm) spacer clears your calipers without altering how the truck handles, and its 108 mm bore (the center hole that fits over the hub) matches GM full-size hubs exactly, so it seats flush and true.
Know the Catch: Because it’s lug-centric, the manual recommends hand installation to avoid over-tightening, and you should budget for a wheel balance afterward.
3. EVIL ENERGY 6×135 1.25-Inch Spacers
The 1.25-inch hub-centric answer for modern F-150s that want a perfect stance without trimming studs.
Ford owners get a dedicated fit here: this set is built for the 6×135 mm pattern used on 2015-2025 F-150s, Expeditions, and even the Lincoln Navigator. The 87.1 mm hub bore with a centering lip seats on the axle hub, preventing wobble at speed.
It’s heavy at 17.46 pounds — about 2.9x the weight of the 1-inch Chevy version — because the hub-centric lip and thicker 1.25-inch billet add material where it counts. The 6061-T6 build and 10.9-grade geomet bolts are the same trusted recipe as the rest of the EVIL ENERGY line.
One F-150 Lightning owner confirmed: “Fit my 23 f150 Lightning without trimming the studs.” Buyers praise the build quality, but fitment reviews are mixed, so verify your truck’s year and hub bore before ordering. A few units arrive with minimal packaging, which matters if you care about unboxing condition.
Hub-Centric Advantage: The centering lip takes load off the studs, and the 1.25-inch width is ideal for F-150 owners who want clearance without a radical push-out.
Verify First: A few owners found the hub bore didn’t align perfectly on older F-150s, so confirm your exact hub spec before purchase.
4. Richeer 1.5-Inch 6×5.5 Spacers
A 1.5-inch set with studs a grade above the rest, holding value across GM, Ram, and Escalade platforms.
The headline spec here is the Grade 12.9 stud, which reaches a tensile strength of 1000MPa — that’s a step above the 10.9 studs used on most competitors, giving better structural support under heavy load. For a towing truck, that extra headroom in the hardware is a real safety margin, not a marketing line.
Coverage is wide: Silverado, Suburban, Avalanche, Sierra, Savana, Express, Ram 1500, and Escalade, all on the 6×5.5 pattern with a 108 mm hub bore. The 1.5-inch (38.1 mm) thickness clears calipers and adds aggression without the rub risk of a 2-inch push.
The crowd favorite detail is fitment: owners on a 2014 Silverado report a perfect hub-centric lip seat, with no vibration up to 85 mph after a correct torque to 140 ft-lbs. Value for money gets steady praise across the board, and the forged 6061-T6 billet with anodized coating handles weather extremes.
Strongest Studs Here: The Grade 12.9 studs exceed the 10.9 standard, and the 108 mm bore fits GM full-size hubs exactly.
One Note: A single owner reported lug nuts spinning while tightening, so use thread locker and hand-start everything before adding torque.
5. SYKRSS 1-Inch 6×139.7 Spacers
A precision-machined 1-inch set that clears calipers for Ram and GM owners chasing a vibration-free highway ride.
This set uses a 77.8 mm hub-centric bore (the center hole that grips the hub), which is smaller than the 108 mm bore on the GM-only spacers in this list. That difference is why it centers perfectly on Ram 1500 and older GM trucks instead of relying on the lugs for alignment. Customers note a flush, vibration-free mount because of that precision.
The manufacturing story is strong: aerospace-grade 6061-T6 forged aluminum, rust-proof 10.9 grade studs, and certification under the IATF 16949:2016 automotive quality system. It also ships with protective gloves and cleaning wire balls, a small touch that shows attention to install detail.
A common real-world use case shows up in the feedback: aftermarket wheels that rub the brake caliper. One owner on an older Silverado confirmed these cleared the caliper completely. The 1-inch width reduces body roll and fixes the tucked-in look without pushing tires past the fenders.
Certified Build: The IATF quality certification and the small hub-centric bore make this a confident pick for Ram 1500 owners who want a true center fit.
Check Your Bore: If your GM truck needs the larger 108 mm bore, this 77.8 mm version won’t center properly, so match the hub spec first.
6. dynofit 2-Inch 6×135 Spacers
A dedicated Ford 2-inch specialist that trades simplicity for serious stance and a 12-month after-sales promise.
This is the one set on the list built specifically for the older Ford crowd: 2004-2014 F-150s, plus Expeditions, Navigators, and the Lincoln Mark LT, all on the 6×135 pattern. The 2-inch (50 mm) thickness is the boldest push-out here, and the M14x2.0 thread pitch is a different spec from the M14x1.5 used on newer Fords — so this is genuinely a 2004-2014 part, not a universal one.
The safety engineering is the story. These are forged, not cast, which resists fracture far better than brittle cast alternatives. The Grade 10.9 Dacromet studs are designed to deform under extreme stress rather than snap without warning — a critical margin for a 2-inch spacer that multiplies leverage on the hardware.
Its 87.1 mm hub bore centers the spacer on the axle, not the lugs, so reviewers point out a tight hub fit, less body roll, and stable highway turns. dynofit includes a 12-month after-sales service, which shows confidence in a part this heavy (18 pounds).
The Safety Case
- Forged 6061-T6 resists cracking where cast spacers fail.
- True hub-centric 87.1 mm bore eliminates wobble.
- Dacromet studs deform rather than snap under stress.
Before You Buy
- The 2-inch width often requires removing crash bars for tire clearance.
- Does not fit dually setups; verify your truck isn’t one.
Reach for this if: you have a 2004-2014 F-150 and want the widest possible stance with forged safety and real after-sales support.
Look elsewhere if: your truck is on factory tires and you don’t want to modify crash bars to clear them.
7. dynofit 1.5-Inch 6×5.5 Spacers
The 1.5-inch middle ground that gives GM trucks an aggressive look without the rub of a 2-inch spacer.
With a 78.1 mm hub bore, this forged set suits GM 1500 trucks and SUVs that run the 6×5.5 pattern. The 1.5-inch (38 mm) thickness clears control arms and adds width with less fender-line risk than 2-inch options. Owners on a leveled Silverado report it eliminates rubbing of 285/45/22 stock wheels completely.
The build is pro-grade: forged 6061-T6 aluminum, SCM435 steel bolts heat-treated to resist snapping, and ISO/DIN 10.9 certified studs. The military-spec black anodizing fights rust, and the CNC machining ensures a precise hub-centric seat. The forged 6061-T6 construction is claimed to be 40% tougher than cast alternatives.
Fit is the top praise by a wide margin, and owners describe holding up well through commuting, towing, and mountain off-roading. The recurring theme is that the 1.5-inch width is “just enough to make it look a little more aggressive” without changing the driving character. One owner needed to sand paint off the center bore for a perfect wheel seat, a minor fit note.
Balanced Aggression: The 1.5-inch width with a 78.1 mm hub-centric bore delivers the aggressive stance without the crash-bar headaches of a 2-inch spacer.
Durability Watch: A small number of shoppers say stud issues over time, so retorque at 50-100 miles and check periodically.
8. KSP 1.5-Inch 6×135 Spacers
A forged 1.5-inch set that bolts flush on modern F-150s and owners say beats the rest on quality.
For 2015-2025 F-150s, Expeditions, and Navigators running the 6×135 pattern, this KSP set is the quality benchmark. It’s forged from black anodized 6061-T6 aluminum with heat-treated 10.9 grade geomet bolts — hardware engineered not to break or strip under daily abuse. The 87.1 mm center bore with a lip gives that true hub-centric seat.
The spec detail that separates it: it’s laser-engraved with sizing and part-number info for easy identification, and the 24 super-strong open-ended lug nuts are included. The recommended torque is 85-95 ft/lbs, and thread locker ships in the box for secure fastening.
The owner feedback is emphatic — quality is the most-discussed point by a huge margin, and fit follows close behind. One owner running a 2.5-inch leveling kit confirmed these completely eliminated tire rubbing. Another specific note: the kit adds about 3 inches to the truck’s stance without pushing tires too far out of the wheel wells. That’s the balance buyers want.
The KSP Edge
- Forged, anodized, and CNC-machined to exact standards for a flush bolted fit.
- Laser-engraved sizing and open-ended lug nuts included.
- Owners confirm no rubbing with a 2.5-inch leveling kit.
The Small Gripe
- The included thread locker tube runs out before you finish all 12 studs.
- Not a fit for pre-2015 F-150s, which use M14x2.0 studs.
Best if: you have a modern F-150 and want a forged, precision hub-centric spacer with the strongest owner-quality consensus on this list.
skip it if: your F-150 is older than 2015 — you need the M14x2.0 thread version instead.
9. KSP 2-Inch 6×5.5 Spacers
The 2-inch, 108 mm hub-centric brute for full-size GM and Ram trucks that tow and haul serious loads.
When you need maximum width and the hub bore to match a full-size truck, this is the set. The 2-inch (50 mm) thickness is the biggest push-out in the 6×5.5 pattern, with a 108 mm hub bore standard for GM 1500, Tahoe, Yukon, and Ram 1500. The forged 6061-T6 aluminum with heat-treated 10.9 grade geomet bolts handles the load.
The real-world proof comes from owners pulling heavy loads: one dually owner uses these to run bigger tires and reports no problems after several heavy hauls. Another put about 3,000 miles on a set and found all studs holding torque perfectly at the recheck. These are the reliability notes that matter when you’re asking a spacer to hold up a loaded truck.
It’s lug-centric in the sense that the 108 mm bore is shared across many GM models, so the fit centers on the hub. KSP backs it with a “30-day refund, 12-month free replacement” service, and the set includes thread locker for fastening. Quality is the top praise, with fit close behind.
Built for Load: The forged 6061-T6 build and 10.9 grade studs are proven on heavy hauling, and the 108 mm bore matches full-size GM and Ram hubs.
The Trade-off: At 2 inches wide, plan for potential tire rubbing on stock fenders, and a few owners note small vibrations around 60 mph that balancing can address.
Understanding the Specs
Bolt Pattern (PCD)
This is the circle of lug holes, written like 6×5.5 or 6×135. The first number is the lug count; the second is the diameter of the circle in inches or millimeters. If this doesn’t match your truck’s hub, the spacer won’t sit flush and wheel studs will carry an unfair load.
Hub Bore and Hub-Centric Fit
The hub bore is the center hole. A hub-centric spacer has a lip that matches your axle hub exactly, so the weight rides on the center. A lug-centric spacer centers on the studs instead, which works but puts more stress on the hardware. For heavy trucks, hub-centric is the safer choice.
Stud Grade and Material
Most quality spacers use 6061-T6 aluminum, either forged or billet, which resists cracking. The studs are rated by grade: 10.9 is the standard, while 12.9 (like on the Richeer set) is a step stronger. Heat-treated studs resist stretching and snapping under load.
Torque and Retorque
Every spacer needs to be torqued to spec with a wrench, not an impact gun, to avoid over-stressing the studs. Plan to retorque after the first 50-100 miles, then check periodically. Skipping the retorque is the most common cause of spacer failure.
