Toyota Supra GR A90 MK5 ARP 12pt Head Stud Kit

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 head bolts. Optimum design, enhanced reliability, and increased strength are the main attributes that separate these ARP head stud kits from the rest.
