TH400 Aluminum Direct Drum


ATI Performance Products, Inc. introduces its new TH400 Aluminum Direct Drum. Holding up to six clutches, this drum contains a new super duty sprag, which is good for a whopping 1,500 ft. lbs of torque.

Comprised of newly machined retainers, as well as inner and outer races, there are no cut down OEM parts. The aluminum drums are made of heat-treated aircraft aluminum. This eliminates the need for steel bushings and sleeves that can expand under heat and come loose, which would ultimately lead to transmission breakdown. As an added value, ATI confidently offers a full one-year warranty against sprag failure.

Log on to or call ATI at (800) 284-3433 to speak with a sales technician today to find the latest information on the Aluminum Direct Drum including all part numbers, accessories, product descriptions and prices.
