Much more reliable than factory bolts

  • NOTE1: UHL stands for Under Head Length of the bolt.
  • NOTE2: These high-performance items are not eligible for any further discounts or promotional pricing.

Flywheel/Flexplate bolts are an important bolt with regards to vehicle performance and safety. ARP manufactures the highest quality 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 chrome-moly 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 bolts have flat, 12-point heads with a larger shank diameter for increased strength and flywheel/flexplate register. Get the best, get ARP!
