Frequently Asked Questions

Will these work with my existing socket wrench set?

Standard hex sockets won't fit — these use spline drive, so you'll need a matching spline socket. Most common automotive tool sets don't include them, so verify before ordering.

Do the lock nuts screw onto the regular lug nuts?

Yes. Install the spline nut first, then thread the lock nut on top to prevent vibration and loosening. Tighten both according to your vehicle's service manual torque spec.

Are these designed for track use or daily driving?

Aluminum lug nuts work for both. They're lighter for road and track, but aluminum can strip if over-torqued — stick to OEM torque specs and re-check periodically on high-vibration builds.
