ARP Pro Series Flywheel Bolt Kit [M11 x 1.5] (CHEVROLET 90° V6 & 305-502 V8 w/ 1 Piece Rear Seal)

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.

NOTE 1: All flywheel and flexplate bolts listed below are Pro Series 200,000 psi rated bolts unless noted otherwise.
NOTE 2: The thread size of metric fasteners is listed using international designations. For example, “M10” indicates a 10mm thread size.
