ARP Pro Series ARP2000 studs are centerless ground and heat treated prior to thread rolling and machining, with a nominal rating of 220,000 psi. These fasteners provide a 40% increase in tensile strength compared to OEM Torque to Yield (TTY) bolts. All bolts are precision centerless-ground and thread-rolled to Mil-S-8879 specifications, featuring a black oxide finish that protects against wear and corrosion.

Each kit includes hardened parallel washers for even load distribution and accurate torque readings.
