Far superior to any other main bolt kit offered for use in competition engines, ARP main bolts are designed to meet the exacting standards and demands of professional engine builders. Forged from 8740 chrome moly, all bolts feature generous under-head radius and rolled threads for the utmost reliability. The threads are rolled after heat-treating, which makes them about 1000% longer fatigue life than most main bolts, which are threaded prior to heat-treating. Available in the popular High Performance Series, which at a nominal rating of 180,000 psi, is a premium replacement for OEM fasteners, or the 200,000 psi nominal rated Pro Series , application-specific main bolts with reduced wrenching head and are designed for use in competition applications. Parallel-ground, hardened washers are included with each kit

FLYWHEEL BOLTS

Flywheel and Flexplate bolts play an important role in the performance and safety of race cars and street machines alike. That's why the fastener experts at ARP have developed special bolts that are far superior to OEM hardware. ARP offers two styles of Flywheel/Flexplate bolts: The premium grade Pro Series, originally developed for NASCAR competition, has a 200,000 psi rating and the High Performance Series is rated at 180,000 psi. They are both forged from aerospace alloy and heat-treated prior to thread rolling and machining. Both feature an exclusive, flat, 12-point head design and larger than stock shank diameter for increased strength and improved flywheel register. Complete with washers and nuts where applicable.
