Much more reliable than factory bolts

Flywheel/Flexplate bolts are an important bolt with regards to vehicle performance and safety. ARP manufactures the highest quality flywheel/flexplate bolts on the market due to their attention in using outstanding materials and paying attention to the littlest details in manufacturing. The high-performance series of flywheel/flexplate bolts are made from 8740 chromoly steel and heat-treated so that they have a tensile strength in the 180,000 psi range—much stronger than factory bolts. The ARP "Pro Series" is made from premium-grade steel and heat-treated in-house to a 200,000 psi tensile strength with precision-rolled J-threads after heat-treat. All the ARP flywheel/flexplate bolts have flat, 12-point heads with a larger shank diameter for increased strength and flywheel/flexplate register. Get the best, get ARP!
