ARP, a leader in fastener technology, has just released a new ARP2000 head stud kit for GM Duramax L5P diesel applications.
Part No. 230-4301 includes a set of 36 M12 ARP2000 studs, 12 M8 ARP 8740 chromoly intake valley bolts, 36 chromoly steel 12-point nuts, 36 parallel ground washers and a 1 oz. pack of ARP Ultra-Torque fastener assembly lubricant.
All ARP2000 studs are centerless ground, heat treated prior to thread rolling and machining, nominally rated at 220,000 psi tensile strength and are reusable as compared to the OEM Torque to Yield (TTY) head bolts. Optimum design, enhanced reliability and increased strength are the main attributes of ARP head stud kits.
