Fits '07.5-'10 Allison 4x4 Transmissions. This support can keep your Allison four wheel drive housing from cracking in the event of a driveline vibration (bad u joint, dented or bent driveshaft).
Piece of Mind:
Drive line vibrations from a bad u-joint or other factors can put stress on the 4x4 transmission housing and cause it to crack. Replacing a housing can cost over $1000. Installing a rear housing support can keep your four wheel drive housing from cracking
Built to last:
Our Rear Housing Supports are fabricated in house right here at Merchant Automotive. Using 7/8 .120 wall DOM mild steel tubing for maximum support.
Easy to Install::
The support installs using the factory bolts. This brace can be easily installed in the driveway or garage .
Heavy Duty, Well Built, Easy Install, January 10, 2019 By Anonymous (Mount Clemens, MI)
Very well built, heavy duty just like the truck and transmission it'll be installed in, to protect. Very easy installation, driveway no problem, didn't even need to jack the truck up or drive up on ramps; though it'd probably make it even easier. This does nothing for power, performance, or fuel mileage, but for peace of mind driving around on these awful pothole-riddled Michigan roads, is where the benefit is achieved. It's very easy to see the amount of force that must be applied to the end of the Allison housing as the transfer case/driveshaft hangs off the end and with every bump, hole, drop out, etc., only adds to the force being exerted to the cast housing.
