ARP Dodge Cummins 5.9L 24V (all same length studs) head stud kit

ARP head studs, made from Custom Age 625+ material (260,000 psi tensile strength), prevent cylinder head lifting under high combustion pressures. Kits include heat-treated chrome-moly steel 12-point nuts and parallel ground washers. Studs are manufactured in ARP's Santa Paula, CA plant, with threads rolled after heat-treat for optimal fatigue strength and centerless ground for concentricity. Broached ends facilitate easy installation and cylinder head removal in tight spaces. ARP also offers ARP2000 (220,000 psi minimum) head stud kits for Dodge/Cummins, Chevy Duramax, Ford 7.3L Powerstroke, and 6.0L Powerstroke.
