TH400 Alm Drum Assy Direct w/6-Clutches

The TH400 Aluminum Drum Assembly Direct with 6-Clutches from ATI Performance is designed for high-performance transmission builds and heavy-duty racing applications where reliability under extreme load conditions is essential. This component serves as a vital upgrade for builders seeking maximum holding power and precise engagement characteristics from their Turbo 400 transmissions.

Constructed from aluminum, this drum assembly offers significant advantages over factory steel alternatives, including reduced unsprung weight and improved thermal management. The six-clutch configuration enhances torque multiplication and holding power, minimizing slip and extending the lifespan of components during high-load cycles. Its direct-fit design ensures compatibility with existing TH400 internals, making installation straightforward.

This assembly is particularly beneficial for builders upgrading from cast-iron drums, as it allows for stronger launches and reduced slip. The superior heat-shedding properties of aluminum help prevent clutch fade, ensuring consistent performance during extended racing sessions or towing applications. Whether for a street beast, drag car, or truck platform, this assembly is a critical component for achieving optimal performance.
