Billet Flexplate for use with 2017-2023 Duramax 6.6L L5P engines

The SoCal Diesel Billet Flexplate is a one-piece billet steel design, significantly stronger than the OEM stamped steel flexplate on 2017+ GM Duramax L5P engines. It prevents cracking, warping, or center failure common with stock units under increased torque, aggressive tuning, heavy towing, or high-load conditions. Balanced for a stock crankshaft, it ensures reliable torque transfer between the crankshaft and torque converter. This upgrade is recommended for tuned trucks, heavy towing, performance applications, and competition use, meeting SFI 29.3 specification (requiring replacement every 3 years for competition).
