8 x 6.5" to 8 x 6.5" - 121.4mm Hub Centric / 9/16 Studs (Ram)
8 x 6.5" to 8 x 6.5" - 121.4mm Hub Centric / 9/16 Studs (Ram)
Far From Stock — Billet Wheel Adapter (8×6.5″ ↔ 8×6.5″, 9/16″ Studs, 121.4 mm Hub)
Built the FFS way—true, strong, and centered—for trucks running the classic 8×6.5″ 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.

- 1.5″ thick — 9/16″ studs

Vehicle Fitment (YMM)
Exact-match spec: 8×6.5″ (8×165.1 mm) bolt pattern, 9/16″ studs, and 121.4 mm hub bore.
| Make | Model | Years | Notes |
|---|---|---|---|
| Dodge / Ram | Ram 2500 / 3500 (SRW) | 1994–2011 | 8×6.5″ pattern, 9/16-18 studs, hub bore ≈ 121.3–121.4 mm. Best OEM match. |
Important notes on other 8×6.5″ 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 adapter’s 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: 8×6.5″ ↔ 8×6.5″ (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 8×6.5″ keeps correct mating alignment.
Install Notes
- Verify fitment: Confirm 8×6.5″ PCD, 9/16″ studs, and 121.4 mm hub bore on your vehicle.
- Confirm wheel bore: Ensure your wheel centers properly on the adapter’s hub lip (match hub/wheel seat styles).
- Prep hub: Safely lift and secure vehicle; remove wheel. Clean hub face and bore of rust/paint/debris.
- Test-fit adapter: Slide adapter onto hub; verify full, even seating (no gaps).
- Secure adapter: Install nuts on factory studs; tighten in a star pattern to vehicle manufacturer torque spec.
- Mount wheel: Place wheel on adapter studs; install lug nuts and tighten in a star pattern to spec.
- Spin & clearance check: Rotate by hand to verify no contact with calipers, suspension, or fenders.
- 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.
