Bora 6×135 Wheel Spacers — Precision 70mm Bolt Pattern Fitment
Our 6×135 wheel spacers are precision-machined for Ford F-150, Expedition, and Navigator platforms requiring exact 70mm bolt circle spacing. Each spacer moves your wheels outward 1.5 inches per side, improving stance and clearing larger brake calipers or suspension components.
We machine every unit from billet 6061-T6 aluminum in our USA facility, then apply a mil-spec anodized finish that resists corrosion in salt, mud, and extreme weather. The hub-centric design maintains factory wheel bearing load distribution, while Grade 8 studs preinstalled at the factory eliminate loose hardware concerns. Every set ships with our lifetime structural warranty and detailed torque specifications for your vehicle.

Materials & Manufacturing Process
We machine every 6×135 wheel spacer from billet 6061-T6 aluminum bar stock at our Minnesota facility. This aerospace-grade alloy offers a 45,000 PSI tensile strength rating while remaining 65% lighter than equivalent steel spacers, reducing unsprung weight that affects handling and ride quality.
Our CNC milling process holds tolerances to ±0.001 inches across all critical dimensions — the 70mm bolt circle diameter, 87.1mm hub bore, and stud hole spacing. After machining, each spacer undergoes Type III hard-anodizing, creating a surface hardness of 70 HRC that resists trail damage, road salt corrosion, and brake dust staining. We verify bolt pattern accuracy with coordinate measuring machines before final packaging.
Fitment & Compatibility
Our 6×135 spacers fit 2004-2024 Ford F-150, 2003-2024 Expedition, and 2003-2024 Navigator models equipped with the 6-lug bolt pattern and 70mm pitch circle diameter. The 87.1mm hub-centric bore matches Ford’s factory wheel hub diameter, ensuring proper centering and eliminating the vibration common with lug-centric designs.
Before installation, verify your vehicle’s bolt pattern by measuring center-to-center distance between opposite studs. The 6×135 pattern shows approximately 135mm (5.31 inches) across the 70mm diameter bolt circle. Our spacers do NOT fit 6×139.7 (Tacoma/Tundra) or 5×135 (older F-150) patterns.
Installation Requirements & Torque Specifications
Installation requires removing your factory wheels, cleaning hub faces with a wire brush to remove rust or debris, then sliding each spacer onto the truck’s existing wheel studs. Thread the included lug nuts to 150 ft-lbs in a star pattern to secure the spacer to the hub, then mount your wheel onto the spacer’s studs using factory or aftermarket lug nuts torqued to your wheel manufacturer’s specification.
We include detailed instructions with photos showing proper lug nut tightening sequence and our recommended re-torque schedule: check lug nut tension after the first 50 miles, then every 5,000 miles or during tire rotations. Use anti-seize compound on stud threads (included in our hardware kit) to prevent galvanic corrosion between aluminum spacers and steel lug nuts.

6×135 Wheel Spacer Fitment Questions
Yes, our 6×135 spacers are precision-machined for the 70mm pitch circle diameter found on all 2004-2024 F-150 trucks equipped with the 6-lug bolt pattern. The 87.1mm hub-centric bore matches Ford’s factory wheel hub specification across these model years.
Verify your truck has the 6×135 pattern by measuring 135mm center-to-center between opposite wheel studs. Our spacers will NOT fit 5×135 (older F-150) or 6×139.7 (Toyota) patterns.
Most F-150 owners running 35-inch tires on stock or leveled suspensions choose our 1.5-inch or 2.0-inch spacers to prevent tire rub at full steering lock. The exact thickness depends on your wheel offset and tire width.
Measure from your current tire sidewall to the nearest fender or suspension component, then subtract your desired spacer thickness. We recommend maintaining 0.5 inches of clearance minimum. Our customer service team can help you calculate the right thickness for your specific wheel and tire combination.
When properly installed and torqued to specification, our hub-centric 6×135 spacers are engineered for daily driving, towing, and off-road use. The billet aluminum construction withstands the same loads as your factory wheels, and the hub-centric design maintains proper bearing load distribution.
We recommend re-torquing lug nuts after the first 50 miles and checking torque every 5,000 miles or during tire rotations. Follow your vehicle’s towing capacity limits — spacers do not reduce payload or towing ratings when installed correctly.
The 6×135 bolt pattern has a 70mm pitch circle diameter, which is the diameter of the circle passing through the center of all six wheel studs. You can verify this by measuring 135mm (approximately 5.31 inches) straight across from the center of one stud to the center of the stud directly opposite.
Alternatively, check your driver’s door jamb sticker or owner’s manual for the bolt pattern specification. Ford F-150, Expedition, and Navigator models from 2004-present use the 6×135 pattern with 70mm PCD, while older models may have different configurations.
Yes, our spacers accept Ford factory lug nuts on the wheel-facing studs. We include a separate set of lug nuts for mounting the spacers to your truck’s factory studs, so you’ll need two sets total — one to attach spacers to the hub, one to attach wheels to the spacers.
Factory acorn-style lug nuts work perfectly. If you’re using aftermarket wheels with different seat angles (cone vs. ball), verify your lug nuts match the wheel’s specifications. We stock aftermarket lug nut sets if you need a complete hardware upgrade.
Hub-centric spacers like ours have a precision-machined 87.1mm center bore that slides over Ford’s wheel hub, centering the spacer and transferring vehicle weight directly to the hub bearing. This replicates factory wheel mounting and prevents vibration.
Lug-centric spacers rely only on wheel studs for centering, which can cause vibration, premature bearing wear, and uneven load distribution. Our hub-centric design with the exact 70mm bolt circle ensures proper fitment and safe operation under all driving conditions.
Wheel spacers themselves do not automatically void your Ford warranty under the Magnuson-Moss Warranty Act — manufacturers must prove that an aftermarket part caused a specific failure to deny a warranty claim. However, if a wheel spacer installation error causes damage (improper torque, wrong bolt pattern), Ford may deny claims related to that damage.
We recommend keeping installation records, torque specifications, and our product documentation. Properly installed hub-centric spacers that maintain the correct 70mm bolt circle alignment do not affect suspension geometry or create conditions that would void coverage for unrelated components.
