Add extra keys from accessories on the right, if needed.
Fitment and specs
- Thread size: 12x1.25 (12mm stud, 1.25mm thread pitch)
- 6-spline tuner style drive, turns only with the matching spline key

Start every nut by hand a few turns to avoid cross-threading, then tighten in a star pattern using the spline key and a torque wrench set to the spec in our torque reference chart. Skip the impact gun on the final pass to protect the black finish. Re-torque after 50 to 100 miles of driving.
Common questions
Will these fit my vehicle?
They fit studs threaded 12x1.25, and the match must be exact, so a 12x1.5 stud will not work. Seat type matters just as much: conical, mag, and ball seat wheels each need their own lug style, so check what your wheels require or ask us before ordering.
What if I lose the spline key?
Each set includes one key, and extra keys are sold separately. A standard socket will not grip the spline pattern, so keep a spare key with your jack or in the glovebox.
