Product Description
The REVMAX A1000-901 Billet Flex Plate is a heavy-duty upgrade designed for 2001–2016 GM 6.6L Duramax trucks equipped with the Allison 1000 transmission. Factory flex plates are known to crack, warp, or shear under high torque loads—especially in trucks used for towing or increased horsepower builds.
RevMax engineered this flex plate from precision-machined billet steel to provide significantly greater durability and strength than factory stamped flex plates. Whether your truck is a stock daily driver, tow rig, or high-performance diesel build, the A1000-901 flex plate ensures reliable power transfer between the engine and transmission.
By eliminating the weak points found in factory plates, this billet flex plate helps prevent drivetrain failures that can lead to complete loss of power to the transmission.
Key Features:
- Precision machined billet steel construction

FAQ
Why upgrade to a billet flex plate?Factory flex plates are stamped steel and prone to cracking under high torque or heavy towing. A billet flex plate provides significantly higher strength and reliability.
Will this work with stock Allison transmissions?
Yes. The RevMax A1000-901 is designed to work with factory Allison 1000 transmissions as well as built performance Allison units.
Is this recommended for tuned or high horsepower Duramax trucks?
Absolutely. Trucks running performance tuning or higher horsepower levels benefit greatly from a billet flex plate because the factory units often fail under increased torque loads.
Does this flex plate change engine balance?
No. The A1000-901 maintains the correct internal balance configuration required for the Duramax/Allison drivetrain.
Is installation difficult?
Installation requires removal of the transmission or engine depending on service method. Professional installation is recommended if you are not experienced with drivetrain service.
