Polyurethane transmission mount?

[Spastik Monkey]

Has anyone swapped in a poly tranny mount? I'm looking to stiffen up the driveline a bit, I usually start here on my other builds. I can't find any info on the 6 or 8 speed mount.

I put poly bushings on street cars to stiffen them up. On a truck though if you're doing off-road I would think you would want the truck to articulate more freely as everything is moving around on uneven terrain.

 

I do not off-road so put on swaybars and Bilsteins that help keep it flat thru turns. Not sure i'd go for poly trans bushings though.
