Jeff,

when I replaced mine, I went back with stock rubber mounts. I have Energy Suspension bushings everywhere except for body mounts. I didn't want to feel anymore vibrations in the cab than I do now. The stock rubber will absorb more of it than polyurethane. Of course, I would wait until someone who does indeed have poly mounts to reply before making a decision on what I would do.

One thing I do know for sure. When I replaced my motor and tranny mounts, it really added to what you felt in the cab. It sure makes it easier to feel the engine running. I rather like it though.
