Product Description
The ATS 305-900-4248 Allison Billet Flexplate is a critical upgrade for 2001-2005 6.6L Duramax engines, designed to eliminate the common failure points found in factory flexplates. Built from high-strength billet material, this flexplate delivers superior durability and reliability under high horsepower and torque conditions.
The factory flexplate in Duramax applications is prone to cracking and failure, especially in trucks with performance tuning, heavy towing, or increased power levels. The ATS billet flexplate is engineered to handle extreme stress, providing a stronger connection between the engine and transmission while ensuring long-term reliability.
Ideal for both stock replacement and high-performance builds, this flexplate is a must-have upgrade when installing a performance transmission, torque converter, or increasing engine output.
