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: High Performance and Pro Series. They are both forged from aerospace alloy and heat treated prior to machining and thread rolling. Both feature an exclusive, flat, 12 point head design larger than stock shank diameter for increased strength and improved flywheel register. The popular High Performance series is rated at 180,000 psi, and the premium grade Pro series, originally developed for NASCAR Winston Cup competition are rated at 200,000 psi. Complete with washers and nuts where applicable.
