8 x 170mm to 8 x 170mm / 14 mm x 1.5 (Ford)

Far From Stock Billet Wheel Adapter (8170 8170, 141.5 Studs, 125 mm Hub Bore)

Must order two for a pair. Pricing is for one wheel adapter only.

Hub- and wheel-centric billet adapter designed for Ford Super Duty SRW trucks with an 8170 mm bolt pattern, M141.5 studs, and a 125 mm center bore. Same-pattern design (8170 8170) keeps OEM PCD while adding clearance or stance. Machined from 6061-T6 aluminum billet.

Vehicle Fitment (YMM)

Thread split reference: many 19992002 Super Duty trucks use M142.0; 2003+ commonly use M141.5. Center bore around 125.0125.1 mm is typical for SRW 8170 applications. Always verify your trucks specs.

Key Details

• Bolt Pattern: 8170 mm (vehicle) 8170 mm (wheel)
• Stud Size: M141.5 (see note above for 9902)
• Center Bore: 125 mm hub- & wheel-centric
• Application: Ford Super Duty SRW not for DRW (8200)
• Type: Same-pattern billet adapter (not a conversion)
• Material: Precision CNC-machined 6061-T6 aluminum billet

Why these outperform generic spacers

Stronger than Cast Machined from 6061-T6 Billet

• 6061-T6 aerospace aluminum: Excellent toughness and fatigue resistance for working trucks.
• Hub- & wheel-centric load path: Pilots at hub and wheel face to reduce vibration and distribute load evenly.
• Precision machining: Tight runout and concentricity for highway-speed stability.
• High-strength hardware: Studs and nuts specd to meet or exceed OEM grade requirements.
• OEM geometry preserved: Same-pattern 8170 8170 improves stance without altering mating angles.

Install Notes

1. Verify fitment: Confirm Super Duty SRW with 8170 pattern and M141.5 studs (2003+ typical).
2. Prep hub: Lift and secure vehicle; remove wheel. Clean hub face and center bore of rust/paint/debris.
3. Test-fit adapter: Slide adapter onto hub; ensure full, even seating with no gaps.
4. Secure adapter: Install nuts on factory studs; tighten in a star pattern to the manufacturers torque spec.
5. Mount wheel: Place wheel on adapter studs; install lug nuts and tighten in a star pattern to spec.
6. Spin/clearance check: Rotate by hand to verify no contact with calipers, tie-rod ends, or fenders.
7. Re-torque: After 50100 miles, re-torque adapter and wheel nuts to spec; inspect periodically.

Use fasteners that match your wheel seat style (cone/flat) and follow torque specs in your owners manual/wheel documentation.
