Frequently Asked Questions
Do these work with my existing wheels?
Extended spline nuts fit most aftermarket and OEM wheels with M12 x 1.25 lug holes. Verify your wheel's lug hole pattern before purchase — confirm thread size and spline compatibility with your wheel manufacturer.
How tight should I torque these?
Refer to your vehicle's service manual for proper torque specification. Overtightening aluminum can strip threads; undertightening risks loosening. Use a calibrated torque wrench and follow manufacturer guidelines exactly.
Do these come with installation tools?
This set includes only the lug nuts themselves. You'll need a lug wrench or impact socket (typically 19mm or 21mm) and a torque wrench to install them properly on your wheels.
