Head Stud Kit

ARP head studs provide superior cylinder head clamping and reduced distortion and should be considered essential for every performance engine build. The manufacturing process involves centerless grinding of the blanks for near perfect concentricity and thread rolling after the heat treatment for significantly increased fatigue strength. 8740 Chromoly material has a 200ksi tensile strength and Custom Age 625+ is 260ksi.

Special order.
