Common questions
Why will my socket not grip these?
The duplex spline drive is designed to be turned only by the included key. Slip the key over the nut, then drive the key with a 3/4" or 13/16" socket or wrench. Extra keys are available separately.
How do I make sure the seat matches my wheels?
Check the seat machined into your wheel's lug holes. Conical, mag, and ball seats are not interchangeable, so match what your wheels currently use or ask us with your wheel details.
