Aluminum Clutch Drum w/ Bearing - No Piston

ALUMINUM - DRUM WITH BEARING - NO PISTON

ATI's aluminum drums are made of treated T-6 aircraft aluminum, eliminating the need for steel bushings and sleeves that can expand under heat and come loose, ultimately causing transmission failure.

• Equipped with Torrington bearings
• Triples clutch life
• Lowers ET

The Aluminum Advantage! Remember! The forward drum rotates at engine RPM at all times. The direct drum goes from spinning twice engine RPM in low gear to stopped on the 1-2 gear change and stopped to engine RPM on the 2-3 gear change. Aluminum weighs one-third the weight of steel. The
weight difference is a performance must...less abusive on the sprag and enhances clutch life greatly.
