Far From Stock — Hub & Wheel-Centric Billet Adapter (8×180 → 8×180, 14×1.5 Studs, 125.6 mm Bore)

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

Hub- and wheel-centric billet adapter for GM HD trucks using the 8×180 mm bolt pattern, M14×1.5 studs, and a 125.6 mm center bore. Same-pattern design (8×180 → 8×180) maintains OEM geometry while adding clearance or stance. Machined from 6061-T6 aluminum billet.

Tech note: Many OEM hub-bore listings for GM 8×180 show ~124.1–124.2 mm. If your hub measures ~124.1–124.2 mm, use an appropriate centering ring to properly pilot to 125.6 mm for true hub-centric fit.

Key Details
  • Bolt Pattern: 8×180 mm (vehicle) → 8×180 mm (wheel)
  • Stud Size: M14×1.5
  • Center Bore: 125.6 mm (hub- & wheel-centric)
  • Application: GM 2500/3500 SRW (not DRW)
  • 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 both the hub and wheel face for smooth rotation and even load.
  • Precision machining: Tight runout and concentricity for high-speed stability.
  • High-strength hardware: Premium studs and nuts spec’d to meet or exceed OEM grade requirements.
  • OEM geometry preserved: Same-pattern 8×180 → 8×180 improves stance without altering mating angles.
Install Notes
  1. Verify fitment: Confirm vehicle is GM 2500/3500 SRW with 8×180 pattern and M14×1.5 studs.
  2. Measure hub bore: Check the OE hub. If ~124.1–124.2 mm, have the correct centering ring to pilot to 125.6 mm.
  3. Prep surfaces: Safely lift and secure the vehicle; remove wheel. Clean the hub face and center bore of rust/paint/debris.
  4. Test-fit adapter: Slide the adapter onto the hub to ensure it seats fully and evenly (no gaps). Confirm ring fit if used.
  5. Mount adapter: Install nuts onto factory studs; tighten in a star pattern to the vehicle manufacturer’s torque spec.
  6. Mount wheel: Place wheel onto 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. Road-check and re-torque: After 50–100 miles, re-torque all adapter and wheel nuts to spec; re-check periodically.

Follow your vehicle manufacturer’s torque specifications and use components that match thread type and seat style.
