These Pro series flywheel bolt kits from ARP give you all that you need to bolt in your flywheel with confidence.
They're much stronger than OEM hardware, are forged from aerospace alloy, and are heat-treated prior to thread rolling and machining.
These bolts feature an exclusive, flat 12-point head design and a larger-than-stock shank diameter for increased strength and improved flywheel register.
