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

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

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

Hub- and wheel-centric billet adapter built for Ford Super Duty SRW trucks using the 8170 mm bolt pattern, M141.5 studs (see thread note below), 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)

Thread note: Many 19992002 Super Duty models use M142.0 wheel studs. This adapter is supplied/configured for M141.5 (common on ~2003+). Always verify your trucks stud pitch before ordering.

Key Details

• Bolt Pattern: 8170 mm (vehicle) 8170 mm (wheel)
• Stud Size: M141.5 (see thread note for 19992002)
• 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: Centers at the hub and wheel face to reduce vibration and distribute load evenly.
• Precision machining: Tight runout and concentricity for 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 your truck is Super Duty SRW with 8170 pattern.
2. Confirm thread pitch: Check a lug nut. ~2003+ typically M141.5; 19992002 often M142.0. Order the matching adapter hardware.
3. Prep: Lift and secure vehicle; remove wheel. Clean hub face and center bore of rust/paint/debris.
4. Test-fit adapter: Slide adapter onto hub; ensure full, even seating (no gaps).
5. Secure adapter: Install nuts on factory studs; tighten in a star pattern to the vehicle manufacturers torque spec.
6. Mount wheel: Place wheel on adapter studs; install lug nuts and tighten in a star pattern to spec.
7. Spin/clearance check: Rotate by hand to verify no contact with calipers, tie-rod ends, or fenders.
8. Re-torque: After 50100 miles, re-torque adapter and wheel nuts to spec; check periodically.

Follow your owners manual/wheel makers torque specs and seat style (cone/flat) for all fasteners.
