I installed Revshift 80a poly trans mounts two weeks ago and returned them in under 12 hours. The vibration was unbearable. And no I didn't tighten them too tight I went back and adjusted it multiple times even to the point of just finger tight. I was pretty surprised that even the softest poly would be like that, so I ordered new OEM ones with lifetime warranty for $5.95 each! I just had my 80a diff bushings in and they feel great! No added NVH at all. Finnegan what would you gauge the NVH to be like with poly engine mounts?
