Bora 2 Inch Wheel Spacers 8×170 – Heavy-Duty Truck Wheel Spacers
Our 2 inch wheel spacers for 8×170 bolt pattern trucks deliver the aggressive stance and clearance you need for larger tires and custom wheel setups. Precision CNC-machined from T6-6061 billet aluminum in the USA, these wheel spacers are engineered specifically for Ford Super Duty F-250, F-350, and F-450 trucks with the 8×170 bolt pattern.
Each spacer extends your wheel track width by a full 2 inches per side, providing improved stability and accommodating wider tires without rubbing. We designed these spacers with hub-centric rings to eliminate vibration and maintain factory wheel balance. Every set includes hardened steel studs that are grade 10.9 or higher, pre-installed and torqued to exact specifications.
Our 2 inch 8×170 wheel spacers meet or exceed SAE J2530 standards and come with our lifetime structural warranty. Whether you’re building a show truck or need functional clearance for off-road tires, these spacers provide the precise fitment and durability you expect from Bora.
- 2 inch (50.8mm) spacer thickness for 4 inches total track width increase
- 8x170mm bolt pattern – fits Ford Super Duty F-250, F-350, F-450 (1999-2004)
- 125mm hub bore with precision hub-centric rings included
- T6-6061 billet aluminum construction – CNC-machined in the USA
- Pre-installed grade 10.9 hardened steel studs with 14×2.0 thread pitch
Precision Engineering & Manufacturing Standards

We machine every Bora 2 inch wheel spacer from solid T6-6061 billet aluminum blocks using multi-axis CNC equipment at our facility in the USA. This heat-treated aluminum alloy provides exceptional strength-to-weight ratio while resisting the constant stress cycles wheel spacers endure.
Our manufacturing process includes precision boring to achieve tolerances within 0.001 inches for the hub-centric rings. This tight tolerance eliminates the vibration and wobble common with lower-quality spacers. Each spacer receives mil-spec Type II anodizing for a durable, corrosion-resistant finish that stands up to road salt, brake dust, and harsh weather conditions.
Fitment & Compatibility Information

These 2 inch wheel spacers are engineered specifically for trucks with the 8x170mm bolt pattern, which includes Ford Super Duty F-250, F-350, and F-450 models manufactured from 1999 through 2004. The 125mm hub bore matches factory specifications for these vehicles.
Before installation, verify your truck has the 8×170 bolt pattern and that your wheels have sufficient clearance inside the barrel. Each spacer adds 2 inches of offset per wheel, creating 4 inches of additional track width total. This spacing typically accommodates tires up to 35-37 inches depending on your suspension setup and wheel backspacing.
Installation Requirements & Torque Specifications

Each set of Bora 2 inch wheel spacers for 8×170 trucks includes everything needed for professional installation. We pre-install grade 10.9 hardened steel studs with 14×2.0 thread pitch and apply industrial-grade thread locker at the factory. The kit includes premium lug nuts specifically sized for use with our spacers.
Installation requires standard hand tools including a torque wrench, socket set, and jack stands rated for your vehicle weight. Clean the hub face and wheel mounting surface thoroughly before installation to ensure proper seating. We recommend applying a thin layer of anti-seize compound to the hub face before mounting the spacer.

Questions About Bora 2 Inch Wheel Spacers 8×170
Our 2 inch wheel spacers are designed specifically for Ford Super Duty F-250, F-350, and F-450 trucks manufactured from 1999 through 2004 with the 8x170mm bolt pattern and 125mm hub bore. Verify your truck’s bolt pattern and hub bore before ordering.
These spacers add 2 inches of offset per wheel, creating 4 inches of total track width increase. Check that your wheels have sufficient inner barrel clearance and that your fenders can accommodate the wider stance.
Adding 2 inches of spacing per side pushes your wheels and tires outward by that amount, which typically allows you to run tires that are 2-4 inches wider than stock depending on your wheel backspacing. Most customers use our 2 inch spacers to accommodate 35-37 inch tires without rubbing.
Actual clearance depends on your specific suspension setup, wheel offset, and tire width. We recommend test-fitting after installation to verify clearance through full steering lock and suspension travel.
Yes, our 2 inch wheel spacers are engineered for heavy-duty truck applications including towing. We manufacture them from T6-6061 billet aluminum with pre-installed grade 10.9 hardened steel studs that exceed OEM strength specifications.
Each spacer meets SAE J2530 performance standards and is tested to withstand loads far beyond typical vehicle requirements. Many of our customers use these spacers on work trucks and towing rigs without issues. Proper installation and torque maintenance are essential for safe operation.
Yes, when using 2 inch wheel spacers you’ll need lug nuts that are compatible with the exposed stud length. Our spacers come with pre-installed studs, and we include the correct lug nuts for mounting your wheels to these studs.
The included lug nuts are specifically sized to provide proper thread engagement without bottoming out. Always use the lug nuts provided with our spacer kit or verify compatibility if using aftermarket lug nuts.
Re-torque all spacer and wheel mounting fasteners after the first 50-100 miles of driving following initial installation. This initial re-torque accounts for any settling that occurs as the spacer seats against the hub and the wheel seats against the spacer.
After the initial re-torque, check fastener torque during regular tire rotations or any time you remove the wheels. If you frequently drive on rough terrain or use your truck for towing, inspect torque more frequently as part of your maintenance routine.
We do not recommend stacking wheel spacers as this practice compromises safety and creates multiple potential failure points. If you need more than 2 inches of spacing, we offer thicker single-piece spacers designed to provide that spacing safely.
Our 2.5 inch wheel spacers for 8×170 trucks provide additional clearance in a single precision-machined unit. Using one properly engineered spacer of the correct thickness is always safer than stacking multiple thinner spacers.
Hub-centric wheel spacers like our 2 inch 8×170 model use a precision-machined center bore that matches your vehicle’s hub diameter. This design centers the spacer on the hub itself rather than relying on lug nuts for centering, which eliminates vibration and maintains proper wheel balance.
Lug-centric spacers center only on the lug studs, which can create vibration and uneven load distribution. Our hub-centric design with tight tolerances (within 0.001 inches) ensures smooth operation and proper load transfer through the hub as the vehicle manufacturer intended.
