Rear Housing Support - Allison Transmission 2011-2019 Duramax
The Merchant Automotive transmission Rear Housing Support can help prevent the 4WD Allison transmission housing from cracking in the event of excessive driveline vibration. These vibrations can be caused by something as simple as a failing U-joint or as complex as a driveshaft imbalance from a dent or even a bend. Also remember that the transfer case itself is heavy and is only supported by being bolted to the back of the transmission, installing the Rear Support Brace provides additional support for trucks that are used off road and in harsh conditions where the weight of the transfer case alone can cause cracking and damage to the transmission case.
Features & Benefits:
- Peace of Mind: Installing the Merchant Automotive Rear Housing Support can keep the Allison transmission housing from cracking, potentially saving $1,000 or more to replace a transmission housing that is cracked or damaged from driveline vibration.
- Built to Last: Our Rear Housing Supports are fabricated in-house and precision welded using state-of-the-art robotic welding equipment at the Zeeland, Michigan Merchant Automotive facility. The support uses high-quality 3/16-inch plate steel that is precision laser cut to ensure exact fit on the transmission and transfer case within each truck. The plates are linked together with 7/8-inch 0.120-inch wall thickness DOM mild steel tubing for MAximum support backed by the Merchant Automotive Limited Lifetime Warranty.
- Easy to Install: The Rear Housing Support can easily be installed in your garage or driveway using basic hand tools and the factory bolts.

While you are improving the driveline stability with the Rear Support Brace consider installing the Merchant Automotive High Performance Motor Mounts and Polyurethane Transmission mount to really lock down the complete drivetrain solidly in the truck's chassis.
