The Socal Diesel Flexplate replaces your stock 3 piece flexplate/flywheel assembly with a fully billet steel design. With increased torque from the engine, the stock assembly becomes vulnerable to cracking in the center which can lead to catastrophic failure. Protect your drivetrain with the HEAVY DUTY Socal Diesel Billet Flexplate.
Features:
-
Lighter and stronger than stock
-
SFI 29.3 approved for competition use
-
SFI certified flywheel flex plate is required on drag racing vehicles running 11.99 and quicker in the 1/4 mile and 7.49 and quicker in the 1/8 mile, or any vehicle exceeding 135 mph. It was changed in 2008 from the 29.1 SFI specification to the SFI specification 29.3 for automatic transmission flex plates for diesel applications. The new rules for the flex plate requires that the material cannot be a stamped metal as are many OEM and after market flex plates. To maintain the SFI specification 29.3 requirements, the flex plate must be replaced every three years.

Dmaxstore Note:

The stock bolts are torque to yield so they will need to be replaced when replacing the flexplate on your Duramax we would recommenced replacing the flexplate bolts with OEM replacements or our DmaxStore Performance Flexplate bolts.
