Q. Will polyurethane motor mounts cause my truck to vibrate more?

A. There is a myth that polyurethane components are harder than rubber. This comes from history, where there were different formulations and suppliers, as well as the intent to dampen the vibration in the higher horsepower and torque vehicles. Polyurethane can be formulated to be as soft or hard as rubber mounts. Rubber can age rapidly, and often cracks, crumbles, or distorts due to harsh road environments and conditions, thus affecting other driveline components. Polyurethane properties can be modified to address certain characteristics to fulfill application and customer's needs.

STEMCO GAFFTM polyurethane is formulated to each application and provides the best possible combination of hardness and resilience for Durability and Performance; historically, harder manufactured mounts would allow unwanted vibration. STEMCO GAFFTM polyurethane mounts have addressed these issues with no excessive vibration and provide better durability and performance.

    Jeff, every question here leads to a "myth" in your answers. Want to talk about myths? How about the myth that big OEs are meeting the mandates for RSD with viable solutions that aren't creating new problems for wheel-end components? It's not just the linings that lead to stopping power, and it seems this website only wants to promote that it's squarely on reman brakes.
