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.

  • 2.0″ 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
  1. Verify fitment: Confirm 8×6.5″ PCD, 9/16″ studs, and 121.4 mm hub bore on your vehicle.
  2. Confirm wheel bore: Ensure your wheel centers properly on the adapter’s 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 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.

Surprisingly good!
Format: Paperback
I came into this with a certain amount of skepticism and was glad to read the author's candid remarks about learning about how she uses sound to help people out. McKusick does a good job of weaving together personal experiences, interactions with others and published scientific picture to give a complete view about how energy flows through us in much different ways then we are aware of or that we allow ourselves to investigate and explore. She has put in years to learn more about electricity, the connection of the body with sound and how pain can be an indicator of more than your physical body. Anyone with an open mind, even someone like me who's not a Deepak Chopra type of person, will take things away from this and will learn more about something they haven't heard about before reading this book. Good overall read!
