Hi All,

I have a 2017 Z71 crewcab long bed Duramax. Found out my drivers rear shock is leaking after 23K miles. I’ve done some searching on here and on “Fans” and the recommendations seem to be for lifted trucks or off-road duty. I don’t go off-road with the truck, all on-road with some short distance towing (#5500 enclosed trailer). My hitch has leveling bars and anti-sway. I’ve read that people say the Z71’s ride is harsh, I don’t find that but that could be because of the blown shock or because I’m used to driving a 1999 K2500 diesel Suburban which is extremely rough. I don’t mind spending the money for good shocks but I definitely don’t want a stiff ride. I’ve used Bilstein’s before but always on cars where I wanted a stiffer ride. I’d like a comfortable ride but I don’t want something that feels like driving on marshmallows and will float all over the road.

I see Rock Auto has KYB GR-2/Excel-G’s and Monroe OE Spectrum for daily drivers as well as Rancho RS5000X’s for heavy duty. Don’t know if anyone has opinions on any replacement shocks. If people say the stock shocks are harsh then I assume the ACDelco’s are also going to be harsh.

Thanks,
Art.

I've used Rancho RS5000s, RS9000s, and Biltsteins on several trucks. Can't go wrong with any of them. I personally prefer the Bilsteins. They seems to be better material and I've never had any issues with the ride being too harsh.

FWIW
swapped out the rears at 1K miles because I didn't care for the way it handled with the factory shocks. It made a nice noticeable handling difference for the positive. Did the same thing on my last truck which was a Toyota with the same results although I used Rancho RS5000 on that vehicle. On the Colorado I used RS7000.

Go with Bilstein 5100s. They give you the flexibility to level your front end if you so desire. They are a little stiffer than factory and much stiffer than rancho shocks, but you get better body roll/ sway control as a trade off. If you are on road more than most days, I don’t think you can get a better riding shock for overall performance.
