ARP High Performance Series flywheel bolts are far superior to OEM hardware. They're forged from aerospace alloy and heat-treated prior to thread rolling and machining. They feature an exclusive, flat, 12-point head design and a larger-than-stock shank diameter, for increased strength and improved register.
