Common questions

How many locks go on each wheel?
The usual setup is one lock per wheel in place of one standard bolt, so this 4-piece set covers a full vehicle.

Do lock bolts have to match my existing bolts?
On the fitment basics, yes: 12x1.5 thread, a conical seat, and a shank length that suits your wheels, which is 23mm on this set. Conical, ball, and mag seats are different shapes and do not interchange, so match the seat to your wheel.
