ARP Pro Series ARP2000 studs are precision centerless-ground, heat treated prior to thread rolling and machining, and nominally rated at 220,000 psi. Compared to OEM Torque-to-Yield (TTY) bolts, they provide a 40% increase in tensile strength. Threads are rolled to Mil-S-8879 specifications, and the black oxide finish helps protect against wear and corrosion.

Each kit includes hardened parallel washers to promote even load distribution and more consistent torque readings.
