ARP’s heat-treated 8740 chrome moly extended wheel studs are a much-needed replacement for any competition car. These work great for Mk3, MK4, MR2's, and IS300's that require extended wheel studs. They have a tensile strength of 190,000 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.
