Bora 2 Inch Wheel Spacers 8×6.5 | Premium HD Bolt-On Spacers
Our Bora 2 inch wheel spacers 8×6.5 are engineered for heavy-duty trucks running the classic eight-lug bolt pattern found on Chevy Silverado 2500/3500, GMC Sierra HD, and older Dodge RAM models. This two-inch spacer pushes your wheel centerline outward for a wider track width, delivering better cornering stability and an aggressive stance that fills the fender wells.
Each spacer is CNC-machined from T6-6061 billet aluminum for strength-to-weight efficiency. We include hubcentric rings matched to your vehicle's hub bore, eliminating vibration and ensuring proper wheel centering. The anodized finish resists corrosion from road salt and moisture, and every kit ships with hardened steel studs pre-installed for immediate bolt-on installation.
What makes this 2 inch spacer stand out
Materials & machining precision
Every Bora 2 inch wheel spacer 8×6.5 begins as a solid billet of T6-6061 aluminum, heat-treated to achieve optimal tensile strength. We machine each spacer on a five-axis CNC mill, holding tolerances within 0.001 inch to ensure flush contact against the hub face and even stud load distribution.
The anodizing process forms a hard oxide layer that resists salt spray, brake dust, and road grime. Hardened steel studs are press-fitted into the spacer body and secured with industrial-grade thread locker, eliminating the risk of stud loosening under load. The same engineering principles we apply to our 8×170 two-inch spacer for Ford Super Duty trucks carry over to this 8×6.5 variant, ensuring consistent quality across all bolt patterns.
Hubcentric fit & vibration elimination
Generic lug-centric spacers rely solely on wheel studs to center the wheel, which can introduce vibration at highway speeds. Our hubcentric design includes precision-machined rings that register against your vehicle’s factory hub diameter, transferring vehicle weight through the hub bore rather than the studs.
Installing the hubcentric rings
Each kit ships with rings sized for the most common hub bores in the 8×6.5 family. Slide the ring onto the spacer’s pilot boss until it seats flush, then mount the spacer to your hub. The ring remains captive between the spacer and your wheel’s center bore, maintaining alignment throughout installation. This approach mirrors OEM wheel mounting and prevents the wheel wobble that can occur with non-hubcentric alternatives.
Compatibility & load rating
The 8×6.5 bolt pattern appears on Chevrolet Silverado 2500/3500 (1999–2010), GMC Sierra 2500/3500 (1999–2010), and Dodge RAM 2500/3500 (1994–2011 for the 8×6.5 variant, before the switch to 8×6.5 on later models). This spacer is rated for axle loads up to 3,500 pounds per corner, suitable for stock and moderately lifted HD trucks.
Before ordering, confirm your wheel’s backspacing will clear brake calipers once the wheel is pushed outward by two inches. Wheels with deep dish or very low offset may contact suspension components. We recommend a minimum of 5.5 inches of backspacing for most HD truck applications when using a 2.0 inch spacer.

Common questions about our 2 inch 8×6.5 wheel spacers
Yes, the 8×6.5 bolt pattern was standard on Silverado 2500HD and 3500HD models from 1999 through 2010. Confirm your truck has eight lug nuts per wheel arranged in a 6.5-inch diameter circle. The spacer will mount to your factory hub using the existing studs, and your wheel will then bolt to the spacer's pre-installed studs.
Verify your wheel has adequate backspacing to clear brake calipers and suspension components once moved outward by two inches. Most factory and aftermarket wheels with 5.5 inches or more of backspacing will work without issue.
No, every Bora 2 inch 8×6.5 spacer kit includes hubcentric rings sized for the most common hub bores on Chevy, GMC, and Dodge HD trucks. The rings are precision-machined to fit the spacer's pilot boss and your vehicle's hub diameter, ensuring proper centering and eliminating vibration.
If you have an unusual hub bore size due to aftermarket hubs or axle modifications, contact us with your exact measurements and we can supply custom rings at no additional charge.
Re-check torque on both the spacer-to-hub nuts and the wheel-to-spacer nuts after the first 50 miles of driving. Aluminum spacers can experience minor settling as they go through heat cycles, which may reduce clamping force slightly.
Check again at 500 miles, then incorporate a torque check into your regular maintenance schedule every 5,000 miles or before any long trip. Always use a calibrated torque wrench and follow your vehicle's OEM torque specification, typically 140 ft-lbs for most HD trucks in the 8×6.5 family.
Yes, as long as the wheel has the correct 8×6.5 bolt pattern and sufficient backspacing to clear your brakes and suspension after being pushed outward by two inches. A wheel with very low or negative offset may contact the upper control arm or fender liner once spaced out.
Measure from the wheel's mounting surface to the inner barrel edge—this is your backspacing. Subtract two inches to simulate the spacer's effect. If the result is less than 4.5 inches, you may encounter clearance issues on lowered or heavily loaded trucks.
Our 2 inch 8×6.5 spacers are rated for axle loads up to 3,500 pounds per corner, which covers most stock and moderately modified HD truck applications including towing and light off-road use. The billet aluminum construction and hubcentric design distribute load evenly across the hub face, reducing stress concentrations that can cause cracking.
For extreme off-road use involving repeated high-impact landings or competition rock crawling, consult with us about your specific application. In most towing and trail scenarios, these spacers perform identically to OEM wheel mounting when properly installed and maintained.
Hubcentric spacers use a precision-machined ring that registers against your vehicle's hub bore, centering the spacer and wheel before the lug nuts are tightened. This transfers vehicle weight through the hub rather than relying solely on the studs, eliminating vibration and reducing stress on the wheel studs.
Lug-centric spacers have no centering feature and depend entirely on the lug nuts to align the wheel. This can introduce vibration at highway speeds and place uneven load on the studs, leading to premature wear or loosening. Hubcentric designs are the OEM-equivalent mounting method and are strongly recommended for daily-driven vehicles.
Wheel spacers are considered an accessory modification similar to aftermarket wheels. Most manufacturers do not void the entire vehicle warranty for spacer installation, but any failure directly caused by the spacers—such as suspension damage from improper fitment—may not be covered. Always consult your dealer before modifying a vehicle under warranty.
Spacers do not change suspension geometry or toe/camber settings, so wheel alignment is typically not required after installation. However, if you notice uneven tire wear or pulling after installing spacers, have your alignment checked to rule out pre-existing issues that may have been masked by the original wheel offset.
