Common questions

Do I need the key for removal too?
Yes. The spline pattern only engages with the key, whether you are installing or removing, so keep it with your jack and spare tire tools. Extra keys are available separately if you want a backup.

How do I know these will seat correctly on my wheels?
Match both the 12x1.25 thread and the seat type your wheels are machined for. Conical, mag, and ball seats are not interchangeable, so verify the seat before ordering.
