Frequently Asked Questions
Do I need to prep or clean the studs before installing these?
Yes — wipe the wheel studs clean of any rust or debris before threading these on. The grooved shank grips best on a clean surface, which ensures a secure fit every time.
Will these work with my factory wheels or are they only for custom setups?
These are built for wheels with deeper or offset designs where standard-length lugs won't reach far enough. If your factory wheels are shallow, standard-length nuts are a better fit. Measure your stud exposure before ordering.
What's the torque spec for these lug nuts?
Refer to your vehicle's service manual for the correct torque value — it varies by vehicle. The grooved shank prevents rotation during tightening, so you can apply proper torque without the nut spinning on you.
