ARP wheel stud

Running big rubber with big power? You want strong wheel studs. Running spacers? You need long wheel studs. They're even useful for autocrossers or anyone else who changes wheels often. They're longer than stock to allow the use of wheels with a thicker hub. 1.25" longer than stock, with a bullet end to ensure your lug nuts thread on straight even in the heat of competition. Open-ended lug nuts may be required.

NA6, NC and ND use a 0.507" knurl on the front and the rear.
NA8 and NB use a 0.507" knurl on the front and a 0.579" on the rear.

Sold individually, you will need 4 studs per wheel on an NA, NB or ND and 5 per wheel for an NC.

Installation note: it is tempting to use a lug nut to pull these into the hub, but ARP does not recommend that due to potential thread damage. It's better to press them in. Some applications will require you to remove the hub from the car for installation.
