Heavy-Duty Rear Housing Support for Duramax Allison Applications

The Sinister Diesel Transmission Rear Housing Support SDRHSDMAX0107 fits 2001-2007 GM Duramax LB7, LLY, and LBZ trucks equipped with the Allison automatic transmission. This support system reinforces the rear transmission housing on 4×4 trucks exposed to heavy driveline stress and vibration. It helps reduce the chance of transmission housing damage caused by worn driveline components. Additionally, it provides added drivetrain stability for demanding towing and performance applications.

Helps Prevent Transmission Housing Damage

A bad U-joint or damaged driveshaft can create severe driveline vibrations over time. Those vibrations can eventually crack the transmission housing and lead to expensive drivetrain repairs. Therefore, reinforcing the rear housing area becomes important for long-term durability. In addition, extra support helps reduce stress placed on the transmission during heavy use.
