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. Standard material is ARP2000 alloy with a 220ksi tensile strength. Custom Age 625+ is an optional high strength (260ksi) material for more demanding applications.

Usually ships in 2 to 3 days.
