Ultimate Duramax Flex-Plate Upgrade

The BD Diesel FleX-Plate is the gold standard for modified 2001-2011 Duramax 6.6L engines paired with the Allison transmission. Designed to withstand up to 1,500 lb-ft of torque, this unit is essential for anyone running increased power levels. Unlike stock units that are prone to cracking under high-torque loads, this forged steel replacement offers unmatched durability.

Engineered for Performance

  • High-Torque Capacity: Rated for up to 1,500 lb-ft of torque, making it perfect for towing or racing.
  • Forged Steel Construction: Twice as thick as the factory unit to eliminate flex and failure.
  • Corrosion Resistant: Features a black oxide coating to prevent hydrogen embrittlement and rust.
  • SFI Certified: Meets the safety requirements for competitive racing sanctioning bodies.

Whether you are building a dedicated drag truck or a reliable tow rig, the BD Diesel FleX-Plate ensures your power is transferred efficiently to the transmission. It is a direct, bolt-in replacement that works seamlessly with both stock and most aftermarket torque converters. With a focus on precision balancing, you can expect reduced vibration and improved overall engine longevity. Upgrade your Chevy Silverado or GMC Sierra with confidence by choosing high-performance parts from GGCRACING.
