Description If you are needing to replace the tranny mount on your 4wd 1st Gen, don’t replace it with another soft squishy rubber mount that will flex and quickly fatigue. Replace it with a reinforced polyurethane one! We have run these mounts for over a decade in our trucks (including higher horsepower trucks) and can vouch for the durability and quality of the mount. They handle the twist of high output Cummins engines like a champ! Comes with two upper and lower mounts, and two bushings. Be sure to get a set of our poly engine mounts too!
