Far From Stock — Hub & Wheel-Centric Billet Adapter (8×6.5″ → 8×6.5″, 14×1.5 Studs, 116.7 mm Hub Bore / 121.2 mm Wheel Bore)

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

Engineered for vehicles with an 8×6.5″ (8×165.1 mm) bolt pattern and factory M14×1.5 studs. Hub-centric to 116.7 mm (vehicle hub) and wheel-centric to 121.2 mm (wheel bore) to keep both sides precisely piloted. This is a same-pattern adapter (8×6.5″ → 8×6.5″), not a bolt-pattern conversion. Machined from 6061-T6 aluminum billet.

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: 116.7→121.2 mm piloting reduces vibration and shares load correctly.
  • Precision machining: Tight runout/concentricity for highway-speed stability.
  • High-strength hardware: Premium studs and nuts spec’d to meet or exceed OEM grade.
  • OEM geometry preserved: Same-pattern 8×6.5″ keeps correct mating alignment.
Install Notes
  1. Verify fitment: Confirm 8×6.5″ (8×165.1 mm) PCD, M14×1.5 studs, and 116.7 mm hub bore on your vehicle.
  2. Confirm wheel bore: Ensure your wheels have a 121.2 mm (≈121.2–121.3 mm) center bore to seat on the adapter lip.
  3. Prep hub: Safely lift/secure vehicle; remove wheel. Clean hub face and center 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’s 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 50–100 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 owner’s manual.
