Hey guys, so I just did a write up about installing GMT900 rear cab mounts onto my '96 c1500 to help with the ride quality. There was another guy on here that I remember mentioning the swap which got me interested in it, but I can't for the life of me find that thread anymore...so whoever you were, thanks for the suggestion...

its apparently a fairly common swap among the GMT800 diesel guys, but thought y'all might be interested in it, since I haven't heard of many GMT400's that have done it. here's my write up on it:

Ok so this only replaces the two rear mounts.. What about the other 4 mounts ?

The other 4 are a little different, in the GMT900's they still use the same front 4 mounts as our trucks do, its only the rear ones that are the updated ones. I'm not 100% sure on why they only changed the rear ones, but I think it might have something to do with adding too much play between the components mounted to the front of the cab/firewall/etc, which isn't an issue at the rear since nothing is mounted directly to the rear of the cab itself.

Thanks dude I miss read the write up at first that you replaced all 6 mounts with these new hydraulic mount... So basically replace the front four with new poly mounts and replace the rear two with these hydraulic ones?

yeah you can do that, I just used stock rubber mounts for the front 4, but poly ones would work. then the rear mounts with the GMT900 rears...

Do you have a link for where you bought the mounts?

I don't have a link, and I wouldn't recommend the place I got them from anyways, they sent different part numbers, sent obviously used items as 'new', had poor customer service, etc, had to go back and forth with them several times before I got the correct parts...its been a while, I can't even remember the store name off the top of my head.

as far as any other tips for a better ride, upgrading/replacing old shocks helps out a lot (especially if you're still using the original factory shocks, a shock lifespan is ~50k miles give or take), I like the bilstein 'comfort ride' series, they're not as stiff as the HD ones...your tires will also play a huge roll in how it rides.
