DogBone Flexplate Bolt Kit for 2001-2025 6.6L Duramax

Replace your OE flexplate bolts with these 8740 chromoly fasteners from DogBone. Our bolts work perfect with Stock, SoCal, ATS, BD Diesel, and Goerend FlexPlates. These fasteners have a tensile strength of over 220,000psi and feature the same alloy as our proven successful head studs. Aside from excellent tensile strength, our threads are rolled after heat treat which provides a much higher quality thread and minimizes thread fatigue. This bolt is designed to match the length, size, weight and threads that will best benefit your application. 

Converting your Duramax over to chromoly bolts will greatly increase the clamping load on your flexplate. These bolts are a must on trucks with upgraded flexplates!
