Bora 2" Wheel Spacers 6×135 | 14mm x 2.0 Studs
Our 2-inch wheel spacers for the 6×135 bolt pattern are precision-machined from T6 6061 aerospace aluminum to deliver the aggressive stance F-150 and Expedition owners demand. Each spacer is hubcentric with a 87.1mm pilot diameter, maintaining factory wheel balance while pushing your wheels two full inches outward for improved track width and clearance for larger tires.
We engineer every set with twenty pre-installed 14mm x 2.0 thread pitch studs — ten per spacer — heat-treated to SAE J1199 Grade 10.9 standards. The studs extend 2.8 inches beyond the spacer face, providing secure thread engagement for factory or aftermarket lug nuts. Each spacer is mill-balanced to within 0.002 inches and anodized with a corrosion-resistant black finish that withstands salt spray and highway debris.
What makes the 6×135 2-inch spacers different
Material Engineering & Manufacturing Precision
We machine every Bora 2″ wheel spacer for the 6×135 pattern from solid T6 6061 aluminum billet using five-axis CNC equipment. The aluminum alloy undergoes solution heat treatment at 990°F followed by artificial aging at 350°F, yielding a minimum tensile strength of 45,000 psi and a Brinell hardness of 95.
Our manufacturing process holds machining tolerances to ±0.001 inches across the mounting face, ensuring flush contact with both the hub and wheel. The hubcentric bore is precision-turned to 87.1mm with a 0.0005-inch concentricity spec, eliminating vibration caused by lug-centric designs. Each spacer undergoes mill balancing before anodization — we remove material from non-critical areas until rotational imbalance measures below 0.002 inches, matching OEM wheel balance standards.
Stud Specifications & Thread Engagement
14mm x 2.0 Thread Pitch Requirements
The 6×135 bolt pattern uses a metric thread pitch of 14mm x 2.0, matching Ford’s factory stud specification for F-150 and Expedition models. We press-fit each stud into the spacer body with 0.001-inch interference, then apply red Loctite 271 threadlocker to prevent rotation under torque cycling.
Each stud extends 2.8 inches beyond the spacer mounting face, providing 1.1 inches of usable thread length for your lug nuts after accounting for wheel thickness. Ford recommends a minimum of 0.75 inches of thread engagement — our studs exceed this by 47 percent, ensuring safe clamping force even with thicker aftermarket wheels. We heat-treat all studs to SAE J1199 Grade 10.9 standards, delivering a minimum tensile strength of 150,000 psi and a proof load of 120,000 psi per fastener.
Fitment Compatibility & Installation Sequence
These 2-inch spacers fit any vehicle with a 6×135 bolt pattern and 87.1mm hub bore. Primary applications include 2004-2024 Ford F-150 (all trim levels), 2007-2024 Ford Expedition, and 2007-2024 Lincoln Navigator. The spacers are not compatible with 6×139.7 (6×5.5″) Toyota and Nissan patterns or the older Ford 5×135 pattern found on early Explorer and Mustang models.
Installation Torque Procedure
Install the spacer to the vehicle hub using factory lug nuts torqued to 150 ft-lbs in a star pattern. Mount your wheel to the spacer studs using factory or aftermarket lug nuts (14mm x 2.0 thread) torqued to 150 ft-lbs. Re-torque all fasteners after the first 50 miles, then inspect monthly for the first three months. We include red Loctite 271 with each set for optional application to the wheel-to-spacer interface — this is not required but recommended for track or off-road use.

Common questions about the 6×135 2-inch spacers
Yes, these spacers fit all 2023 F-150 models with the factory 6×135 bolt pattern and 87.1mm hub bore. This includes XL, XLT, Lariat, King Ranch, Platinum, Limited, Tremor, and Raptor trims. The spacers maintain the factory hubcentric fit and work with both stock and aftermarket wheels.
Verify your truck has the 6×135 pattern by measuring the distance between opposite stud centers — it should measure 135mm or 5.31 inches. All F-150 models from 2004 to present use this bolt pattern.
Torque the spacer to the vehicle hub at 150 ft-lbs using your factory lug nuts in a star pattern. Then torque your wheel to the spacer studs at 150 ft-lbs using lug nuts with 14mm x 2.0 threads.
Re-torque both interfaces after the first 50 miles of driving. Check torque monthly for the first three months, then every oil change thereafter. Use a calibrated torque wrench — impact wrenches can exceed the recommended torque and damage the studs.
Adding a 2-inch spacer effectively reduces your wheel offset by 50.8mm. A wheel with +44mm offset becomes -6.8mm offset after installation. A wheel with +20mm offset becomes -30.8mm offset.
For backspacing, subtract two inches from your current measurement. A wheel with 6.5 inches of backspacing becomes 4.5 inches of backspacing with these spacers installed. This moves the wheel mounting surface two inches farther from the vehicle centerline.
Yes, you can use factory Ford lug nuts on the spacer studs as long as they are the conical seat 14mm x 2.0 type. The studs extend 2.8 inches beyond the spacer face, providing 1.1 inches of thread engagement after accounting for typical wheel thickness.
Ford OEM lug nuts require a minimum 0.75 inches of thread engagement for safe clamping force. These spacers exceed that requirement by 47 percent. Do not use tuner-style lug nuts with a shank diameter larger than 14mm — they will not thread properly.
No, you do not need longer hardware. The spacers come with twenty pre-installed studs (ten per spacer) that extend 2.8 inches beyond the spacer mounting face. Your factory lug nuts thread directly onto these studs.
You use your factory lug nuts twice — once to attach the spacer to the vehicle hub, then again to attach your wheel to the spacer studs. Make sure your lug nuts are in good condition with clean threads before installation.
Yes, these spacers work with any aftermarket wheel that has a 6×135 bolt pattern and sufficient center bore clearance. The spacer's outer face has a 78mm register, so your wheel's center bore must be at least 78mm or larger.
The spacers are most commonly used with aggressive negative-offset wheels (+0mm to -25mm) that would otherwise sit too far inboard without spacers. They also work with high-positive-offset wheels (+40mm and higher) to bring them flush with the fender. Verify your wheel has 14mm x 2.0 lug nut holes.
Installing 2-inch spacers increases scrub radius by moving the wheel centerline outward while the steering pivot remains in the factory position. This creates slightly heavier steering feel at low speeds and increases steering feedback over uneven surfaces.
The wider track width reduces body roll and improves lateral stability during cornering and lane changes. Suspension travel and camber curves remain unchanged because the spacers do not alter ride height or control arm angles. Most drivers report improved highway stability with minimal change to parking-lot maneuverability.
