Description

The APR main studs are an upgrade over the stock factory bolts that may stretch over time.

Includes a set of ten, M10 ARP2000 main studs, a set of ten, M8 ARP2000 main studs, twenty 8740 chromemoly steel 12 pt nuts and a 1/2 oz. pack of ARP Ultra-Torque fastener assembly lubricant.

All 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 50% increase in tensile strength over the OEM main bolts.
