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.
