Cab Mounts Question

[69sixpackbee]

I can't remember so please help an ol' boy here. Are C-10 cab mounts different from C-20 & 30's? I kinda remember this being said. Heres the dilemma. I have a set of Energy Suspension cab mounts (#3.4108G) that is for C10's The number for c-20's and 30's is different. Can these I have right now be used on a 3/4 ton cab?

Thanx

Yup they are different. IIRC the rubber that the cab sits on is the same but the rubber under the mount is bigger, I could be wrong on this though, it has been a few years since I replaced mine. You can buy the rubbers at your local GM dealer.

If memory is working, the 3/4 ton 2wd's, & the 4wd trucks had a taller cushion at the rear of the cab......swap the rear frame brackets, & you should be able to use the 1/2ton pcs for mounts(someone chime in if im off on this).....69L

yes the 1/2 and the 3/4 ton are different. the 3/4 ton rear mounts rubber bushings are about 2 inches taller. this is because the 3/4 ton frame rear cab mount brackets are lower on the frame. the front are the same.

Yes, the rubber on the bottom side of the bracket is taller on the 3/4 ton , & the 4wd trucks. It has to do with where the steel bracket is riveted to the frame......you can swap brackets/mounts, as long as you understand that 1/2 ton is different than 3/4 ton(rear brackets & cushions), & dont mix the pcs best of luck, L
