Flexplate Bolt Fastener Kit

For over three years, DHD fasteners have been setting the benchmark for quality, performance and value. Don't be fooled by inferior late arrivals to the fastener market.

Replace your OE flexplate bolts with these 8740 chromoly bolts (45mm) from DHD. 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, the threads are rolled after heat treat which provides a much higher quality thread and minimizes thread fatigue. This bolt kit 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 flywheel. These bolts are a must on vehicles with upgraded flexplates. Replaces OE Bolt 11610965.
