Silicone body mounts

it helped mine, but not really a night and day sort of thing. At this point,so many years later, just having any new mounts would probably be a huge upgrade, LOL.

I believe GM started using the hyd mounts on the LMM chassis but could be incorrect. I believe the TSB is from the 09-10 era. I recently helped a buddy one night after work put in new mounts on his 03 crew cab. He sourced the front four and I sourced the rear two from GM and he went with the hydraulic mount. It helped a bunch but like James said, there's only so much that can be done to account for the expansion joints in the freeway.

Not for crew cab. You click the button and add $175. I was pretty shocked.

Good catch, didn't notice that.
