Re: 1991 C1500 2WD Coilover

Can any one help me with this plz
I'm getting the funds together to do coilovers on my truck also. There is a thread already on here about doing coilovers and someone posted about the setup he used on his truck. Uses QA1 musclecar coilover kits that utilize a tapered spring and mounts in place of your existing shocks. The top of the shock is a stud mount and the bottom is a bar mount just like the OE shocks. The spring uses the threaded coilover mount and the top uses the factory spring pocket. Should work pretty good, just trying to figure out what spring rate to use now.

If you're going all out race truck, do some 800lb fronts and 600lb rears. That'll be a VERY stiff ride, for a little softer and streetability, drop 200lbs off each of those values.

I've seen people running anywhere from 500# to 1000# on GMT800's. The 500-800# for 1/2 tons and 700-1000# for the HD trucks (duramax included).

If you want to save money, a rear sway bar and good shocks alone can make a huge difference to the handling in the rear. Plus you won't have to mess with track bars, even though they do help traction in general, it's just that they get expensive and/or time consuming to do.

I just added a sway bar from a C1500 Suburban...LOVE IT! (I got the links from a '90s F-expedition, [but recently discovered that pretty much the whole rear sway system from the Avalanche will fit the C1500 as well]). I currently have some AC Delco professional monotubes, but I ordered some Gabriel spring assist shocks (coilovers) to help keep the rear axle triangulated, and I'll be ordering some Aldan American 700# coilovers for the front soon. I'll let you know how it goes.
