ARP's heat-treated 8740 chrome moly wheel studs are a much-needed replacement for any car engaged in oval track or drag racing competition. 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.
