Fitment and specs
- Thread size: 1/2"
- Seat style: acorn (conical) seat
- Design: duplex acorn profile
- Confirm fit against the vehicles listed in the description above
Start every nut by hand for the first few turns so the threads engage cleanly, then snug them in a crossing star pattern and torque to your vehicle's factory specification using the torque reference chart. Re-torque after 50 to 100 miles of driving, since the seats settle once the wheels take load.
Common questions
How do I know these match my wheels?
These use an acorn conical seat, which is the tapered cone style. Conical, ball, and mag seats are not interchangeable, so check that your wheel's lug holes are the tapered cone type before installing.
How do I confirm my thread size?
These are cut for a 1/2" thread. Match it against a nut currently on your vehicle or the applications shown in the description above.
