8 x 170mm to 8 x 170mm / 14 mm x 2.o (Ford) Hub Centric

Far From Stock Hub & Wheel-Centric Billet Adapter (8170 8170, 142.0 Studs, 125 mm Bore)

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

Hub- and wheel-centric billet adapter for early Ford Super Duty SRW platforms using the 8170 mm bolt pattern, M142.0 studs, and a 125 mm center bore. Same-pattern design (8170 8170) maintains OEM geometry while adding clearance or stance. Machined from 6061-T6 aluminum billet.

Vehicle Fitment (YMM)

Tech notes: Early Super Duty (9902) commonly uses M142.0 studs; later (03+) changed to M141.5. SRW hub bore is typically ~124.9125 mm. Always verify your trucks stud pitch and hub bore.

Key Details

• Bolt Pattern: 8170 mm (vehicle) 8170 mm (wheel)
• Stud Size: M142.0 (early Super Duty)
• 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 the hub and wheel face to reduce vibration and spread load evenly.
• Precision machining: Tight runout and concentricity support high-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 M142.0 studs (9902 typical).
2. Prep hub: Lift/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 (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; check periodically.

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