8 x 6.5″ to 8 x 6.5″ – 121.4mm Hub Centric / 14mm x 1.5″ Studs (Ram)

Far From Stock Billet Wheel Adapter (86.5 86.5, 141.5 Studs, 121.4 mm Hub)

Built the FFS waytrue, strong, and centeredfor Ram HD trucks running the classic 86.5 pattern with a 121.4 mm hub bore. These billet adapters use 141.5 studs and are available in multiple 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)

Designed for 86.5 (8165.1 mm) bolt pattern, 141.5 studs, and ~121.4 mm hub bore.

Thread split: Earlier Ram HD (19942011) commonly used 9/16-18 studs on 86.5. This adapter is for M141.5 only.
Always verify bolt pattern, hub bore, and stud size for 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 on Ram HD hubs
• M141.5 press-in studs for heavy-duty clamping force
• Same-pattern adapter: 86.5 86.5 (no bolt-pattern conversion)
• Multiple thickness options to set stance and clearances

Why these outperform generic spacers

Stronger than Cast Machined from 6061-T6 Billet

• 6061-T6 aluminum: Toughness and fatigue resistance for real-work trucks.
• True hub & wheel centering: Correct piloting reduces vibration and shares load properly.
• Precision machining: Tight runout and concentricity for highway-speed stability.
• High-strength hardware: M141.5 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, M141.5 studs, and hub bore ~121.3121.4 mm on your truck.
2. Check wheel bore: Ensure your wheel centers properly on the adapters hub lip (match seat style cone/flat).
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 the 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 required by your wheels and owners manual.
