Bora 3 Inch Wheel Spacers – Heavy-Duty 10-Lug Hub-Centric Spacers
Our Bora 3 inch wheel spacers are precision-machined for trucks running 10-lug wheel patterns, delivering the aggressive stance and tire clearance you need for lifted heavy-duty pickups. Each spacer is CNC-machined from billet T6061 aluminum with a hub-centric design that eliminates vibration and ensures proper centering on your factory hubs.
We engineered these spacers specifically for Ford F-250/F-350, Chevy/GMC 2500/3500, and RAM 2500/3500 models. The 3 inch width pushes your wheels outboard to accommodate wider tires, aftermarket suspension, and larger brake kits while maintaining safe bolt engagement. Every kit ships with Grade 8.8 wheel studs pre-installed and corrosion-resistant anodized finish for years of reliable performance in all conditions.
- 3.00 inch thickness for maximum stance and tire clearance
- 10-lug bolt pattern (8x170mm, 8x180mm, or 8×6.5 depending on application)
- Hub-centric machined bore for vibration-free installation
- T6061 billet aluminum construction – lightweight and corrosion-resistant
- Pre-installed Grade 8.8 wheel studs with proper thread engagement
Precision Machining & Hub-Centric Design
Every Bora 3 inch wheel spacer is CNC-machined to aerospace tolerances, ensuring perfect fitment on your truck’s factory hubs. Our hub-centric design means each spacer features a machined pilot bore that mates precisely with your vehicle’s hub register, transferring vehicle weight through the hub rather than the wheel studs.
This hub-centric engineering eliminates the vibration and wobble common with lug-centric spacers. We hold dimensional tolerances under 0.002 inch across all critical surfaces, so your wheels sit perfectly centered every time. The result is smooth highway driving, even tire wear, and zero stress on your wheel bearings or suspension components.
Fitment Guide – 10-Lug Heavy-Duty Trucks
Our 3 inch wheel spacers are engineered specifically for heavy-duty pickups running 10-lug wheel patterns. Compatible applications include Ford F-250, F-350, and F-450 Super Duty trucks (2005-current) with 8x170mm bolt pattern, Chevrolet and GMC 2500HD and 3500HD models (2011-current) with 8x180mm pattern, and RAM 2500 and 3500 trucks (2012-current) with 8×6.5 inch pattern.
Before ordering, verify your truck’s specific bolt pattern and hub bore diameter. We offer application-specific versions matched to your exact factory specifications. The 3 inch width is ideal for trucks running 35-37 inch tires on leveled or lifted suspensions, providing the clearance needed to avoid rubbing during full suspension travel and steering lock.
Installation & Torque Specifications
Installing Bora 3 inch wheel spacers requires basic hand tools and attention to proper torque values. Begin by loosening your wheel lug nuts, raising the vehicle on a quality jack, and securing it on jack stands rated for your truck’s weight. Remove the factory wheel, clean the hub face thoroughly to remove any rust or debris, and test-fit the spacer to confirm proper seating.
Slide the spacer onto your factory hub studs and torque the factory lug nuts to manufacturer specifications in a star pattern. This secures the spacer to the hub. Next, mount your wheel onto the spacer’s new studs and install the lug nuts, torquing them to your vehicle’s recommended specification. We recommend re-checking torque after 25 miles, 50 miles, and 100 miles of driving to ensure proper seating and safety.

Common questions about 3 inch wheel spacers
Our Bora 3 inch wheel spacers are engineered specifically for 10-lug heavy-duty pickups including Ford F-250/F-350 (8x170mm), Chevy/GMC 2500/3500 (8x180mm), and RAM 2500/3500 (8×6.5 inch). We offer application-specific versions matched to your truck’s exact bolt pattern and hub bore diameter.
Before ordering, verify your vehicle’s bolt pattern and confirm that your aftermarket wheels have sufficient depth to clear brake calipers with the added spacing. The 3 inch width is ideal for lifted trucks running 35-37 inch tires.
Yes, hub-centric spacers like our Bora 3 inch models are significantly safer and perform better than lug-centric alternatives. Hub-centric design means the spacer’s machined bore fits precisely over your truck’s hub register, transferring vehicle weight through the hub rather than relying solely on wheel studs.
This proper load distribution eliminates vibration, prevents premature wheel bearing wear, and ensures your wheels remain perfectly centered during all driving conditions. Our hub-centric spacers are machined to tolerances under 0.002 inch for vibration-free performance.
Installation requires removing your wheel, cleaning the hub face thoroughly, and mounting the spacer onto your factory hub studs. Torque the factory lug nuts to manufacturer specifications in a star pattern to secure the spacer to the hub.
Next, mount your wheel onto the spacer’s pre-installed studs and torque the lug nuts to your vehicle’s recommended specification. Re-check torque after 25, 50, and 100 miles of driving. We include detailed instructions, torque specifications, and all necessary hardware with every kit. Professional installation is recommended if you’re unfamiliar with wheel removal procedures.
Quality wheel spacers like our Bora 3 inch models, when properly installed, do not void your truck’s factory warranty. The Magnuson-Moss Warranty Act prevents manufacturers from denying warranty coverage unless they can prove the aftermarket part caused the failure.
Regarding handling, our hub-centric spacers actually improve stability by widening your truck’s track width, lowering the effective center of gravity during towing and cornering. Many customers report improved highway stability and reduced body roll compared to stock wheel positioning.
We machine our Bora wheel spacers from solid T6061 aluminum billet, which offers superior strength and uniformity compared to cast alternatives. Billet construction eliminates the microscopic voids and porosity inherent in casting processes, resulting in consistent material density throughout the spacer.
Our billet spacers also allow us to hold tighter machining tolerances (under 0.002 inch) across all critical surfaces. This precision ensures perfect hub-centric fitment and vibration-free performance that cast spacers cannot match.
No, you use your factory lug nuts with our Bora 3 inch wheel spacers. Each spacer comes with pre-installed Grade 8.8 extended wheel studs that account for the spacer thickness while ensuring proper thread engagement with your existing lug nuts.
The pre-installed studs are engineered to provide safe thread engagement that meets or exceeds SAE standards. You’ll use your factory lug nuts twice during installation – once to secure the spacer to the hub, and again to mount your wheel to the spacer.
Installing 3 inch wheel spacers adds six inches to your truck’s total width – three inches per side on each axle. This increased track width provides the clearance necessary for oversized tires on lifted suspensions while improving stability during towing and highway driving.
Before installation, verify that the additional width keeps your tires within your fender wells or check local regulations regarding tire coverage if you’re running a more aggressive setup. The wider stance also improves cornering stability by increasing your truck’s footprint and lowering its effective center of gravity.
