Flywheel and Flexplate bolts play an important role in the performance and safety of race cars and street machines alike. T
hat'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.
