ARP Head Stud Kit for Mini Cooper S 1.6L Turbo R56 EP6 N12 N14 N16 N18

ARP Pro Series ARP2000 studs are centerless ground, heat treated prior to thread rolling and machining, and are nominally rated at 220,000 psi. These fasteners deliver a 40% increase in tensile strength over the OEM Torque to Yield (TTY) bolts. All bolts are precision centerless-ground and thread-rolled to Mil-S-8879 specs. Each utilizes a black oxide finish that protects them from wear and corrosion. All kits come complete with hardened parallel washers for even load distribution and accurate torque readings.
