When additional horsepower and torque are added to your duramax, you run the risk of cracking the stock flexplate. Designed to handle up to 1500 ft/lbs of torque, the new Duramax Black Oxide coated flexplate is corrosion resistent to prevent hydrogen embrittlement, billet machined and precision balanced for ultimate strength. This flex plate is twice as thick as stock and has passed the stringent 29.3 SFI testing, making it legal for use in race sanctioning bodies specific to High Horsepower diesels. These units are a direct bolt-in and fit any OEM or aftermarket torque converter.

Only Replace the Weak Link! Unlike other manufacturers, we do not require the replacement of the entire flywheel assembly, which is costly and unnecessary. In fact, most flywheel-flexplate assemblies have too little axial thrust (the inability to flex), making them just as succeptable to cracking as a stock flexplate. Save $$ replacing only the flexplate and not the entire assembly.
