Protect Your Allison Transmission from Hidden Driveline Stress

If you drive a 2007.5-2010 Silverado or Sierra 2500HD or 3500HD with the 6.6L Duramax LMM, you know your Allison 4x4 transmission is built to handle serious torque and towing. But even the toughest transmission can suffer damage over time, especially if your driveline develops vibrations from a bad u-joint or a slightly bent driveshaft. The Merchant 10195 Transmission Rear Housing Support is designed to prevent those vibrations from cracking the rear housing of your transmission. It acts as a stabilizing brace, adding strength to one of the most vulnerable points in your drivetrain. Whether you haul heavy loads or spend weekends on the trail, this simple upgrade offers the peace of mind that your transmission is better protected.

Engineered for Durability and Easy Installation

Merchant designed this support to bolt directly onto your existing transmission setup without complicated modifications. It comes with recommended torque specs—35 ft-lbs at the transmission and 27 ft-lbs at the transfer case—so you know exactly how to install it correctly the first time. Once in place, it helps keep everything aligned and stable, reducing the risk of housing cracks caused by vibration or flex. This is a must-have if you’ve already dealt with driveline issues or just want to prevent future damage. Whether your truck works hard on the job site or plays hard on the weekends, this rear housing support helps ensure your Allison stays in one piece, mile after mile.
