Bora 1 Inch Wheel Spacers – Precision-Machined Aluminum Adapters
Our 1 inch wheel spacers are precision-machined from aerospace-grade 6061-T6 aluminum to provide the ideal stance upgrade for your truck or SUV. These adapters push your wheels outward exactly one inch per side, creating improved handling stability and an aggressive appearance without rubbing.
We’ve engineered each spacer with a hubcentric design that maintains factory wheel bearing alignment, eliminating vibration at highway speeds. The bolt-on installation uses grade 10.9 hardened steel studs that exceed OEM torque specifications. With over 30 vehicle-specific bolt patterns available, we’ve refined fitment for Ford, Chevy, Ram, Toyota, and Jeep models to ensure perfect compatibility with your factory wheels and aftermarket rims.

Materials & Construction Standards
We machine every Bora 1 inch wheel spacer from solid 6061-T6 aluminum billet on CNC equipment with tolerances held to ±0.001 inches. This aerospace-grade alloy delivers a tensile strength of 45,000 PSI while weighing significantly less than steel alternatives, reducing unsprung mass that can slow steering response.
The black anodized surface treatment penetrates the aluminum to create a hardened layer that resists road salt, brake dust, and UV degradation. Our grade 10.9 steel studs are heat-treated and cadmium-plated, providing 150,000 PSI tensile strength that exceeds factory lug stud specifications. Each stud is pressed into the spacer body and secured with red thread-locking compound during assembly.
Fitment & Compatibility Across 30+ Applications
Our 1 inch wheel spacers are available in more than 30 distinct bolt pattern and hub bore combinations to match specific truck and SUV platforms. The most common configurations include 5×4.5 (Jeep Wrangler JK/JL), 5×5 (Jeep Wrangler TJ/YJ, Grand Cherokee WJ/WK), 5×5.5 (Ram 1500, older Ford F-150), 6×5.5 (Toyota Tacoma, Tundra, 4Runner, Chevy Silverado 1500), 6×135 (Ford F-150 2004-2014, Expedition), and 8×6.5 (Chevy Silverado 2500/3500 HD, GMC Sierra HD).
Before ordering, verify three measurements on your vehicle: bolt pattern (number of lugs × bolt circle diameter), hub bore diameter, and thread pitch (typically 12×1.5mm or 14×1.5mm for metric, 1/2-20 or 9/16-18 for standard). Our vehicle fitment guide cross-references year, make, and model to the correct spacer specification.
Installation Process & Torque Specifications
Installation requires basic hand tools and follows a bolt-on procedure that takes approximately 45 minutes per axle. Begin by lifting the vehicle on a level surface and supporting it with jack stands rated for the vehicle’s weight. Remove the factory wheel and clean the hub face with a wire brush to remove rust and debris that could prevent proper seating.
Slide the spacer onto the factory hub studs, ensuring the hubcentric bore engages the hub fully before threading on the included lug nuts. Torque these lug nuts to your vehicle’s factory specification (typically 80-140 ft-lbs depending on stud size) in a star pattern across three passes. Mount your wheel to the spacer’s outer studs and torque to the same factory specification.

Common Questions About Our 1 Inch Wheel Spacers
Your bolt pattern is determined by the number of lug studs and the diameter of the circle they form. Count your wheel’s lug holes, then measure from the center of one stud to the center of the stud directly across (for even-numbered patterns) or use our fitment guide which cross-references year, make, and model to the correct specification.
Common patterns we stock include 5×4.5 for Jeep Wrangler models, 6×5.5 for Toyota and Chevy half-ton trucks, 6×135 for 2004-2014 Ford F-150, and 8×6.5 for heavy-duty GM trucks. We manufacture spacers in over 30 different combinations to ensure precise factory fitment.
Our 1 inch spacers are compatible with factory wheels on most applications, adding exactly one inch of spacing per side for a two-inch total track width increase. Before installation, verify that your tire sidewall has adequate clearance to the fender lip and inner wheel well at full steering lock and suspension compression.
Most stock wheel and tire combinations have sufficient clearance, but vehicles with larger-than-factory tires or aftermarket suspension lifts should test-fit before final installation. The spacer does not change wheel backspacing, so if your current setup clears all suspension components, adding spacing will only affect outer fender clearance.
Yes, our wheel spacers are engineered for daily driving, highway use, and moderate off-road conditions when properly installed and maintained. We manufacture each spacer from 6061-T6 aluminum with a tensile strength of 45,000 PSI and use grade 10.9 hardened steel studs rated at 150,000 PSI tensile strength, exceeding OEM specifications.
The hubcentric design ensures proper centering on your vehicle’s hub rather than relying on lug nuts alone, eliminating vibration and maintaining factory wheel bearing alignment. We require re-torquing after the first 50-100 miles and periodic inspection at tire rotations to ensure long-term reliability.
One inch equals 25.4mm, so our 1 inch spacers provide slightly less spacing than a 30mm spacer. If you’re cross-shopping between metric and imperial measurements, note that 30mm equals approximately 1.18 inches, which would be closer to our 1.25 inch spacer option.
We manufacture spacers in both measurement systems to accommodate different regional preferences and OEM specifications. For most North American vehicles, our inch-based sizing (0.5, 1.0, 1.25, 1.5, 2.0 inch) provides standard increments that align with common fitment needs.
We do not recommend stacking spacers, as this practice introduces additional failure points and potential alignment issues. Each spacer is engineered as a single-piece solution with integrated studs torqued and secured during manufacturing.
If you require 2 inches of spacing, order our purpose-built 2 inch wheel spacers which are machined as a single component with appropriately longer studs. Stacking also creates excessive leverage on wheel bearings and can cause premature wear on suspension components.
Re-torque all fasteners after the first 50-100 miles of driving to account for initial settling and heat cycling. After this break-in period, verify torque at each tire rotation interval, typically every 5,000-8,000 miles depending on your vehicle and driving conditions.
Use a calibrated torque wrench set to your vehicle’s factory lug nut specification and follow a star pattern when checking. This periodic inspection takes only a few minutes per wheel and ensures long-term fastener security. Our installation instructions include vehicle-specific torque values for common applications.
Wheel spacers are considered an aftermarket modification, and vehicle manufacturers may evaluate warranty claims on a case-by-case basis. Federal Magnuson-Moss Warranty Act provisions generally prevent manufacturers from voiding entire warranties solely due to aftermarket parts, but they may deny coverage for failures directly caused by modifications.
To protect your interests, retain all installation documentation and ensure spacers are torqued to factory specifications. If a warranty claim arises, the manufacturer must prove the modification caused the specific failure. Many dealerships and manufacturers recognize properly installed wheel spacers as acceptable modifications that do not affect unrelated vehicle systems.
