Fitment and specs

  • Bolts to your 6x5.5" (6x139.7) hub so you can run 6x5" (6x127) wheels
  • 108mm step bore, check your hub diameter before purchase
  • CNC machined billet aluminum
  • Sold as a pair (2 adapters), lug nuts not included
  • Free US shipping

Make sure the hub face is clean and the adapter seats dead flat, then torque the adapter nuts in a star pattern to the value in our torque reference chart. Torque the wheel's lug nuts the same way once mounted. Re-torque both sets after 50 to 100 miles.

Common questions

Are wheel adapters safe?
Yes, when installed correctly. Seat the adapter flat on a clean hub, torque all hardware to spec, verify full thread engagement on every stud, and re-torque after the first 50 to 100 miles.

Will these fit my Tacoma or Tundra?
Yes, if yours is listed: the applications include the Tacoma 4WD 1995-2026 and Tundra 2000-2006, along with the GM trucks listed above. Just confirm your hub fits the 108mm step bore first.
