ARP's heat-treated 8740 chromemoly wheel studs are a much-needed replacement for any car engaged in track or drag racing competition. 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 packaged in sets of 5 and are cadmium plated for extra durability.
