Aluminum Transmission Drums
CNC manufactured in-house from 7075-T6 aluminum billet
because of the outstanding strength properties of the material. Reduces
weight from the transmission's rotating mass without compromising drum integrity. All
drums are designed to hold up to five standard-thickness clutches and are hard-coat
anodized for improved wear characteristics.
