Frequently Asked Questions

Do these fit my current wheels or do I need wheel spacers?

These are extended-length lug nuts designed to work with wheels that sit deeper in the hub or use spacers. Check your wheel hub depth and wheel offset before ordering—your wheel supplier can confirm compatibility.

How do I use the lock nuts in this set?

The set includes both standard and locking lug nuts. Install one lock nut per wheel (usually on one lug hole per wheel) and standard nuts on the remaining holes. The lock nut has a unique spline key pattern that prevents removal without the matching socket.

Can I install these with a standard lug wrench?

Standard lug wrenches won't grip spline-drive nuts. You'll need a spline-drive socket that matches the M12 spline pattern. Standard sockets will slip and damage the nut.
