11-16 LML 6.6L Duramax Sun Coast Billet Flex Plate

Eliminate the weak link of the factory flex plate in your 2011-2016 GM 6.6L Duramax with the Sun Coast A1-BFP-3 Billet Flex Plate. Designed as a direct replacement for the factory flex plate, this billet flex plate features a one-piece design and is a must-have in high performance applications. The flex plate is bolted to the crankshaft, and the torque converter is bolted to the flex plate. Engine torque is transferred to the flex plate, then to the torque converter before reaching your transmission. On modified engines, the horsepower and torque levels can easily destroy the factory flex plate. 


  • Billet Flex Plate
  • Increased Strength

Note: A 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.

Part Number: A1-BFP-3
