ARP Wheel Stud Kit 2.5in Length 5 Pack Most Subaru Models

ARP’s heat-treated 8740 chrome-moly wheel studs are a much-needed replacement for any car engaged in autocross, track, or drag racing. They have a tensile strength of 200,000 psi and are able to easily handle the tremendous acceleration shock loads (shear) and lateral forces (elongation) found in racing. The studs are sold in packs of 5 and are cadmium plated for extra durability. Nuts not included.

Note: An extended stud such as this is a necessity if you will be running a slip-on spacer of more than 5mm, as these are roughly more than 3/4" longer than the OEM Studs.
