Common questions
What happens if I lose the key?
Extra duplex keys are available separately, and it is worth keeping a spare with the vehicle. A standard hex socket will not grip the spline drive, so the shop doing your rotations will need the key too.
How do I know the seat type is right for my wheels?
Match the nut seat to the seat machined into your wheel. Conical, mag, and ball seats are not interchangeable, so check the hardware coming off the wheel first or send us your wheel details.
