Bora 6×5.5 Wheel Spacers — 10mm Precision-Machined Aluminum
Our 10mm wheel spacers transform your truck’s stance while improving handling characteristics and tire clearance. Designed specifically for the 6×5.5 bolt pattern found on popular trucks and SUVs, these spacers deliver measurable performance benefits without compromising safety.
We machine every set from aerospace-grade 6061-T6 aluminum billet for exceptional strength-to-weight ratio. The hub-centric design ensures perfect wheel alignment and eliminates vibration at highway speeds. Each spacer undergoes multi-point quality inspection before it leaves our facility, and we back every set with our lifetime structural warranty.
Whether you’re fitting larger tires, achieving a more aggressive appearance, or correcting wheel offset after a lift kit installation, our 10mm spacers provide the precise solution. The anodized finish resists corrosion in all weather conditions, and our proprietary thread design prevents cross-threading during installation.
- 10mm thickness per spacer for 20mm total track width increase
- 6×5.5 (6×139.7mm) bolt pattern — fits Tacoma, 4Runner, Tundra, Frontier, Xterra, Silverado 1500, and more
- Hub-centric 108mm bore diameter eliminates wheel vibration
- CNC-machined from 6061-T6 aerospace aluminum billet
- M12x1.5 thread pitch with extended studs included
Precision Engineering & Material Selection
We start with certified 6061-T6 aluminum billet — the same alloy used in aircraft structural components. This material delivers tensile strength exceeding 45,000 PSI while maintaining the corrosion resistance essential for automotive applications. Our CNC machining process holds tolerances within 0.001 inch, ensuring perfect hub-centric fit every time.
The hub-centric design is critical to spacer performance. Our 108mm bore diameter matches factory hub specifications exactly, allowing the hub to carry vehicle weight rather than relying solely on lug nuts. This eliminates the vibration and premature bearing wear associated with lug-centric designs.
Installation & Torque Specifications
Tools Required
You’ll need a calibrated torque wrench, 21mm socket, jack and jack stands rated for your vehicle weight, and anti-seize compound. We recommend installing one wheel at a time to maintain three points of vehicle contact.
Step-by-Step Process
Clean the hub face and wheel mounting surface thoroughly with brake cleaner to remove any debris. Apply a thin coat of anti-seize to the hub face, then mount the spacer ensuring full contact. Install factory lug nuts and torque to manufacturer specifications — typically 85-100 ft-lbs for 6×5.5 applications. Mount your wheel to the spacer’s extended studs, then torque the included lug nuts to the same specification.
Vehicle Compatibility & Fitment Notes
Our 6×5.5 wheel spacers fit the bolt pattern used across multiple truck platforms. Toyota Tacoma (2005-present), 4Runner (2003-present), Tundra (2007-present), FJ Cruiser, and Sequoia all use this pattern. Nissan Frontier, Xterra, and Pathfinder share the same 6×139.7mm specification.
Chevy and GMC 1500-series trucks from 2007-2013 also run 6×5.5, though you should verify your specific model year. The 10mm thickness works exceptionally well on stock-height trucks or those with leveling kits up to 2 inches. For lifted applications exceeding 3 inches, consider our 1.5 inch spacers for optimal tire clearance.

What people are saying
Common questions about Bora 6×5.5 wheel spacers
Yes, our 10mm spacers install on any 6×5.5 vehicle without modifications. They fit between your hub and wheel using factory lug nuts to secure the spacer, then you mount your wheel to the extended studs. No drilling, cutting, or suspension adjustments required.
The 10mm thickness works on stock-height trucks and those with leveling kits up to 2 inches. If you’re running a lift exceeding 3 inches or tires larger than 33 inches, measure your fender clearance to ensure adequate space for the wider track.
No, we include a complete set of lug nuts with every spacer pair. The extended studs on our spacers require different lug nuts than your factory ones, so we provide properly-sized black oxide lug nuts threaded for M12x1.5 applications.
You’ll use your factory lug nuts to attach the spacer to your hub, then use our included lug nuts to mount your wheel to the spacer’s studs. Keep your factory lug nuts in case you ever remove the spacers.
Our 10mm spacers add 10 millimeters per side, increasing your total track width by 20mm (approximately 0.8 inches). This means each wheel moves outward 10mm from its current position.
The modest width increase provides noticeable stance improvement without pushing tires beyond factory fender coverage on most applications. You’ll fill out the wheel wells better while maintaining street legality in jurisdictions with track width regulations.
Most truck owners install our spacers themselves with basic tools. You need a jack, jack stands, 21mm socket, and torque wrench. The process takes 45-90 minutes depending on your experience level.
Follow proper torque specifications from our included instructions — typically 85-100 ft-lbs for 6×5.5 applications. We recommend having a professional shop install them if you’re not comfortable with wheel removal or don’t have access to a calibrated torque wrench, as proper torque is essential for safe operation.
Wheel spacers themselves don’t automatically void your factory warranty under the Magnuson-Moss Warranty Act. The manufacturer must prove that the spacer caused a specific failure to deny a warranty claim.
That said, if spacers contribute to a suspension or drivetrain failure, that specific repair might not be covered. We recommend keeping documentation of professional installation if warranty coverage is a concern. Our spacers meet OEM quality standards and we’ve never had a customer report warranty denial related to our products.
Re-torque all lug nuts after the first 50-100 miles following initial installation. This allows the aluminum spacers to seat properly against the hub face and the lug nuts to settle into their threads.
After the initial re-torque, check torque every 5,000-10,000 miles during regular maintenance or whenever you rotate tires. Also check torque after any off-road use, hard cornering events, or if you notice unusual vibration. Proper torque maintenance ensures long-term reliability and safety.
Yes, hub-centric spacers provide superior performance and reliability. Our 108mm hub-centric bore matches your truck’s factory hub diameter precisely, allowing the hub to support vehicle weight just like your factory wheel configuration.
Lug-centric spacers rely entirely on lug nuts to center the wheel and carry weight, which can cause vibration, uneven tire wear, and premature wheel bearing failure. The hub-centric design eliminates these issues by maintaining factory load distribution. You’ll experience smoother operation at all speeds with our hub-centric construction.
