Bora 2-Inch Wheel Spacers 8×180 Bolt Pattern
Our Bora 2-inch wheel spacers are precision-machined for 8×180 bolt pattern trucks, delivering the perfect balance of stance enhancement and structural integrity. Engineered from aerospace-grade 6061-T6 billet aluminum in our USA facility, these 20mm spacers add one inch per side to push your wheels outward for improved stability and aggressive fitment.
Designed specifically for heavy-duty trucks running the 8-lug 180mm pattern, our spacers accommodate the demanding torque and load requirements of full-size pickups and work vehicles. Each set includes Grade 8 installation studs that exceed OEM strength specifications, ensuring secure wheel mounting mile after mile.
Whether you’re installing larger tires, leveling kits, or suspension upgrades, our 2-inch spacers provide the clearance you need while maintaining proper wheel geometry. We mill every spacer to within 0.001-inch tolerance for vibration-free performance at highway speeds.
- 2-inch (20mm) thickness per spacer adds 1 inch per side to track width
- 8×180 bolt pattern fits Chevy, GMC 2500HD, 3500HD (2011-present)
- 6061-T6 billet aluminum construction with natural corrosion resistance
- Hub-centric design with 124.9mm center bore for zero vibration
- Pre-installed Grade 8 wheel studs torqued to factory specifications
Engineering & Construction
We machine every Bora 2-inch wheel spacer from solid 6061-T6 aluminum billet using CNC equipment calibrated daily for dimensional accuracy. This aerospace-grade alloy delivers exceptional tensile strength while weighing significantly less than steel alternatives, reducing unsprung mass that can compromise ride quality and handling response.
Our manufacturing process begins with premium domestic aluminum stock that we verify for composition and hardness. Multi-axis CNC mills cut each spacer to precise specifications, including the critical hub-centric bore that centers on your truck’s axle hub. We then install hardened steel wheel studs using controlled interference-fit pressing that creates a permanent mechanical bond.
Fitment & Compatibility
Confirmed Vehicle Applications
Our 2-inch 8×180 spacers are engineered for 2011-newer Chevrolet Silverado and GMC Sierra 2500HD and 3500HD models equipped with dual rear wheels or single rear wheel configurations. The 8-lug 180mm bolt circle matches factory specifications for these heavy-duty trucks, while our 124.9mm center bore aligns with OEM hub dimensions.
These spacers also fit comparable years of Chevy and GMC chassis cab trucks, utility bodies, and commercial variants running the same axle specifications. Before ordering, verify your current wheel’s backspacing and confirm that pushing wheels outward one inch per side will not cause contact with suspension components, fenders, or body panels during full steering lock and suspension compression.
Installation Requirements
Each Bora 2-inch spacer installs between your truck’s brake rotor hub and wheel mounting surface using the factory lug nuts to secure the spacer to the hub. You then mount your wheel to the spacer’s pre-installed studs using the lug nuts we provide in each kit.
Proper installation requires torquing lug nuts to your vehicle manufacturer’s specifications in a star pattern across two separate stages. We include detailed torque specifications and tightening sequences with every order. After the first 50-100 miles of driving, re-torque all lug nuts to account for initial material settling.

Common Questions About Bora 2-Inch 8×180 Wheel Spacers
Wheel spacers themselves typically do not void manufacturer warranties, but any damage directly attributed to spacer installation may not be covered. We recommend consulting your dealership service department before installation if warranty coverage is a concern.
Our spacers meet or exceed OEM specifications for materials and manufacturing tolerances, and we’ve never received reports of warranty denials solely due to properly installed Bora spacers on stock suspension configurations.
No, our 2-inch wheel spacers come with Grade 8 wheel studs already installed and properly torqued. You’ll use your factory lug nuts to secure the spacer to your hub, then use the lug nuts we provide to mount your wheels to the spacer’s studs.
This dual-mounting system ensures proper thread engagement at both connection points without requiring any additional hardware or modifications to your truck.
With 2-inch (20mm) spacers installed on all four corners, your truck’s total track width increases by 4 inches—1 inch per side on each axle. This means each wheel moves outward 1 inch from its current position.
Measure from your current tire sidewall to the fender edge before ordering to ensure the additional width won’t cause contact with body panels during full steering lock or suspension compression. Most factory fender wells accommodate this width increase without rubbing on stock-height trucks.
We do not recommend stacking wheel spacers of any thickness. Each spacer is engineered as a complete mounting solution with integrated studs designed for single-piece installation between your hub and wheel.
If you need more than 2 inches of spacing, we offer thicker single-piece options including our 2.5-inch spacers that provide additional clearance while maintaining structural integrity and proper load distribution through a single component.
Yes, our 2-inch 8×180 spacers are compatible with aftermarket wheels as long as your wheels maintain the same 8×180 bolt pattern and have a center bore of 124.9mm or larger. Wheels with larger center bores will still mount correctly thanks to the lug-centric loading.
Verify that your aftermarket wheel’s backspacing allows sufficient clearance from suspension and brake components after adding 1 inch of spacing per side. Some deep-dish or highly negative offset wheels may require careful fitment verification.
Re-torque all lug nuts after the first 50-100 miles of driving to account for initial settling of the spacer against the hub and wheel mounting surfaces. After this initial check, inspect torque at each tire rotation service, typically every 5,000-7,000 miles.
We also recommend checking torque before and after any extended towing trips or off-road excursions where wheels experience higher-than-normal stress. Maintaining proper torque ensures safe operation and prevents premature wear on mounting surfaces.
Our anodized aluminum spacers require minimal maintenance beyond keeping them clean during regular wheel cleaning. Remove road salt, brake dust, and chemical residue with mild automotive soap and water to preserve the protective finish.
Periodically inspect the mounting surfaces for any signs of corrosion or wear, and apply anti-seize compound to hub surfaces and studs during wheel removal to ensure easy future service. The anodized finish provides long-term corrosion resistance without additional treatment.
