Built the FFS waytrue, strong, and centeredfor trucks running the classic 86.5 pattern with a 121.4 mm hub bore. These billet adapters use 9/16 studs and are available in 1.5 and 2.0 thicknesses to dial in stance and clearance without changing bolt pattern. Machined from 6061-T6 aluminum billet.

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

Vehicle Fitment (YMM)

Exact-match spec: 86.5 (8165.1 mm) bolt pattern, 9/16 studs, and 121.4 mm hub bore.

Important notes on other 86.5 platforms: Older Ford F-250/F-350 (1998) commonly use 9/16 studs but a larger hub bore (126 mm), and older GM 2500/3500 commonly use a 116.7 mm hub bore. Those do not match this adapters 121.4 mm hub without rings and are not listed as exact fit here. :contentReference[oaicite:1]{index=1}

Always verify bolt pattern, hub bore, and stud size on your exact trim before ordering.

Key Features

• Precision 6061-T6 billet construction for strength and true runout
• Hub-centric to 121.4 mm for proper wheel centering
• 9/16 press-in studs for heavy-duty clamping force
• Same-pattern adapter: 86.5 86.5 (no bolt-pattern conversion)
• Available in 1.5 and 2.0 thickness options

Why these outperform generic spacers

Stronger than Cast Machined from 6061-T6 Billet

• 6061-T6 aluminum: Toughness and fatigue resistance suited for working trucks.
• True hub & wheel centering: Correct 121.4 mm piloting reduces vibration and shares load correctly.
• Precision machining: Tight runout/concentricity for highway-speed stability.
• High-strength hardware: 9/16 studs and matching nuts for robust clamping.
• OEM geometry preserved: Same-pattern 86.5 keeps correct mating alignment.

Install Notes

1. Verify fitment: Confirm 86.5 PCD, 9/16 studs, and 121.4 mm hub bore on your vehicle.
2. Confirm wheel bore: Ensure your wheel centers properly on the adapters hub lip (match hub/wheel seat styles).
3. Prep hub: Safely lift and secure vehicle; remove wheel. Clean hub face and bore of rust/paint/debris.
4. Test-fit adapter: Slide adapter onto hub; verify full, even seating (no gaps).
5. Secure adapter: Install nuts on factory studs; tighten in a star pattern to vehicle manufacturer 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, suspension, or fenders.
8. Re-torque: After 50100 miles, re-torque adapter and wheel nuts to spec; check periodically.

Follow the torque specs and seat style (cone/flat) required by your wheels and owners manual.
