Frequently Asked Questions
Will these work with my factory wheel studs?
These are M12 x 1.25 threaded β they'll mate with factory studs of that size. The extended length is designed to work without modification, but verify your vehicle uses M12 x 1.25 threads before ordering.
Do I need a special socket to install these?
Spline style lugs require a matching spline socket β don't use a standard hex socket. Grab the correct spline tool before install to avoid stripping the nut.
How do the locks actually work?
The integrated locking feature resists vibration-induced rotation. Torque them to your vehicle's factory spec β the lock mechanism engages under normal fastening pressure and holds through normal driving conditions.
