I have a couple of cab mounts that are missing the bottom rubber piece. Is there a good aftermarket cab mount for these truck or do I jus go back with gm parts?

buy the new hydraulic mounts GM uses on the trucks now rides 200% better UPPER 25971031-need 2, LOWER 25791032-need 2, Washers 15854745 need 2 if yours are crap. You know maybe Henry can help order them up for you thru his GM slot. These take that axle wrap down alot which is great on the cement slabs and even racing some.

those are only ment for the rear cab mounts on extended and crew cabs, not ment for all the body mounts

there are some aftermarket poly urethan ones out there for our trucks but the people ive talked to say it makes vibrations easily transfred through to the cab and can cause annoying drones

Replace with OEM. I've broken lots of body mounts. I've used both poly and OEM and will always go back to the OEMs now.

They're for front and back those are GM #'s if you have to look to know something. It's from people who have done it and bought them. Christ!!!!!!!!!!!!!

chill the hell out dude. Those part numbers for those body mounts will not fit in any other location (maybe under the radiator support but that does no good) other than the rear on the 800 chassis. On the 900 i cant say. the hydro mounts are too damn wide to fit in any other location than the rear. plain and simple i know LOTs of guys too who have tried. Hell there is a big ass thread on DP as well. :rolleyes:.

So new hydraulic in the back and factory gm front? Only my front one is shot but I guess I should do them all.

its up to you. the main reason for the hydrolic body mount is for frame beaming as some call it (between 45-55 you can get a bad "hop" so to speak, same deal on bad freeways). the mount allows some up and down flex to keep the frame from transfering so much motion into the cab.

I will probably try the hydraulic ones and seen how that goes. Just to double check they only fit the rear?
