Bora 8×180 Wheel Spacers – 2.0-Inch Bolt Pattern Kit
Our 2.0-inch wheel spacers are precision-engineered for trucks running the 8×180 bolt pattern, including Chevy and GMC 2500/3500 HD models. Each spacer is CNC-machined from billet 6061-T6 aluminum, delivering the strength and corrosion resistance your heavy-duty truck demands.
These spacers push your wheels outward by exactly 2.0 inches per side, creating 4 inches of total track width increase. That translates to improved stability during towing, better cornering confidence, and the aggressive stance truck owners want. We include grade 10.9 wheel studs that exceed OEM specifications, plus all necessary hardware for a complete bolt-on installation.
Every Bora spacer undergoes multi-point inspection before shipping. We stand behind our wheel spacers with a lifetime structural warranty because we build them to outlast your truck.
- 2.0-inch (50.8mm) precise spacing per wheel for 4-inch total track width increase
- 8x180mm bolt circle matches GM 2500/3500 HD factory specs (14mm x 1.5 thread pitch)
- Billet 6061-T6 aluminum construction – 40% stronger than cast alternatives
- 106.1mm hub-centric bore ensures zero vibration at highway speeds
- Grade 10.9 hardened steel studs rated 150,000 PSI tensile strength
Materials & Manufacturing Process
We machine every Bora 8×180 wheel spacer from a single billet of 6061-T6 aluminum using computer-controlled precision equipment. This process creates a grain structure that runs continuously through the entire spacer, unlike cast spacers where porosity can create weak points.
The T6 heat treatment increases tensile strength to 45,000 PSI while maintaining the ductility aluminum needs to absorb road shock without cracking. Our Type II anodizing adds a 0.0007-inch protective oxide layer that’s harder than tool steel, so road salt and brake dust won’t corrode the mounting surface.
8×180 Bolt Pattern Compatibility
Confirmed Vehicle Fitment
These 2.0-inch spacers are engineered specifically for the 8-lug, 180mm bolt circle used on 2011-2023 Chevrolet Silverado 2500/3500 HD and GMC Sierra 2500/3500 HD trucks. The 14mm x 1.5 thread pitch matches your factory wheel studs exactly.
Our 106.1mm hub-centric bore pilots directly onto your truck’s hub, transferring vehicle weight through the machined aluminum rather than the studs. This design eliminates the vibration issues common with lug-centric spacers and maintains your truck’s factory ride quality.
Installation & Torque Specifications
Installation requires removing your existing wheels, mounting the spacer to your hub with the included studs, then reinstalling wheels onto the spacer’s extended studs. We recommend professional installation if you’re unfamiliar with wheel torque procedures.
Torque the spacer mounting nuts to 140 ft-lbs in a star pattern, then torque your wheel lug nuts to manufacturer specifications (typically 140 ft-lbs for GM HD trucks). Re-torque both after the first 50-100 miles as the aluminum seats against the hub surface.

Common Questions About Bora 8×180 2.0-Inch Wheel Spacers
Yes, our 2.0-inch spacers are engineered specifically for the 8×180 bolt pattern used on 2011-2023 Silverado 2500/3500 HD trucks. They’ll work with factory wheels and most aftermarket wheels designed for this bolt pattern.
Before installation, verify that your new wheel position won’t contact suspension components or fender liners at full steering lock. The 2.0-inch spacing pushes your wheels outward by 4 inches total (2 inches per side), so check clearance with your specific tire size.
Hub-centric spacers like our 8×180 model use a precision-machined center bore (106.1mm) that pilots directly onto your truck’s hub. This design transfers vehicle weight through the machined aluminum surface rather than the wheel studs, eliminating vibration and maintaining factory ride quality.
Lug-centric spacers rely on the studs to center the wheel, which can create vibration at highway speeds as the wheel tries to find its balance point. We use hub-centric design exclusively because it’s the engineering standard for heavy-duty truck applications.
No, you do not need longer lug nuts with our spacers. Each Bora spacer kit includes extended wheel studs that protrude through the spacer, providing full thread engagement for your existing lug nuts.
The included studs are grade 10.9 hardened steel rated at 150,000 PSI tensile strength – stronger than OEM studs. You’ll install the spacer to your hub using the mounting nuts we provide, then install your wheels onto the spacer’s extended studs using your factory lug nuts.
Retorque your spacer mounting nuts and wheel lug nuts after the first 50-100 miles of driving to account for initial settling as the aluminum seats against the hub surface. After that initial check, inspect and verify torque every 5,000 miles or during routine tire rotations.
If you frequently drive on rough terrain, tow heavy loads, or operate in extreme conditions, increase inspection frequency to every oil change. The medium-strength thread locker we include prevents loosening while still allowing removal for maintenance.
When properly installed and maintained, quality wheel spacers like our billet aluminum design do not cause measurable bearing wear. The 2.0-inch spacing does create a slightly longer moment arm on the bearing, but the increase is negligible compared to the bearing’s design tolerance.
Factory engineers build substantial safety margins into bearing capacity. The same bearings handle the stress of towing thousands of pounds, emergency braking, and pothole impacts – all of which create forces far exceeding what a 2-inch spacing change produces. We’ve never received a warranty claim for bearing failure attributable to our spacers.
Wheel spacers are legal for street use in all 50 states when properly installed with manufacturer-specified hardware and torque values. They’re considered a bolt-on suspension modification similar to aftermarket wheels or leveling kits.
Some states require that your tires remain within the fender line, so verify your local vehicle code if you’re running aggressive tire sizes. For commercial vehicles or vehicles subject to DOT inspection, consult your fleet manager, as some companies have internal policies restricting modifications beyond factory specifications.
Torque the spacer mounting nuts to 140 ft-lbs using a star pattern to ensure even seating. After mounting the spacer, torque your wheel lug nuts to your vehicle manufacturer’s specification – typically 140 ft-lbs for GM 2500/3500 HD trucks, but verify in your owner’s manual.
Use a calibrated torque wrench rather than an impact gun for final tightening. Impact guns can over-torque fasteners, stretching threads and creating safety issues. We include detailed torque sequences and specifications with every spacer kit.
