I was looking into cab mounts last week. I found some poly ones from Energy too. Mine are shot so I'll be replacing them very soon. Instinct tells me to go with the poly ones but I'll be waiting to hear results from the GM part.

Do you have a link for the GM ones?

Just found these from Prothane KMJ Performance::Polyurethane::Body Mounts::GM::96-06 Chevy Prothane Polyurethane Truck Body Cab Mounts

I wonder if any of our vendors can get any of these options? I see a possible group buy in the future.

From the GM campaign doc:
"New upper and lower mounts should be installed at the left and right rear cab position. The new LOWER mount is a two-piece design, meaning there is a rubber mount with a metal washer. Some models may use a one piece lower mount, meaning the rubber mount has a metal washer molded into it. If the vehicle has the one-piece lower mount design, washers (PN 15854745, Qty 2) will be needed to be used with the new lower mount."

Upper Mount = 25791031 replaced with 25994881 Qty 2
Lower Mount = 25791032 Qty 2
Washer = 15854745 Qty 2 (if needed)

Looks like you need both the Upper AND Lower, its just that the Upper has an updated part#.


I just ordered the Sulastics and will be putting them on tonight. But I'm all for an even MORE comfortable ride!

From what I've read, the lower mount and the washer is the same as what's already on there, just reuse them. I'll hopefully know for sure by the end of next week
