'72 C20 Lift

[Lefkada]

I have searched the forums and have called Rancho Lifts, Tuff County, 4 Wheel Parts, ORW and Moog, but still haven't found a good solution.

I have a '72 C20 (2WD LWB) with original, sagging front coil springs and sagging rear leaf springs. I'd like to get the truck 2-4" above stock height, but cannot find a method to do this. All lift kits I've found online are designed for 4x4's, which have front leaf springs, and I haven't found front coil springs with lift above stock height.

Has anyone found a solution to this? Sorry if this has been answered before.

Big Block camper springs[or one ton] with a spacer and rearched rear leafs?

[Lefkada]

It sounds like this will be the best option. Are there any big issues with using coil spacers?

When I did my front disc conversion on my 69 C20 I changed out the front springs. Never did anything with the rears. I installed some HD springs (P/N 2772074) bought from NAPA. Tires didn't rub at all. They were 285/70-17 tires with H2 Hummer wheels. The ride was a bit stiff, but hey it's a 3/4 ton truck. Here's a comparison of the springs:

The stock HD C20 springs are as follows:

Free Height: 12.94"
Spring ID: 3.68"
Spring Load Height: 10"
Design Load: 2950
Spring Rate: 1016
Wire Diameter: 0.812"

The springs I put on from C10, C20, C30 from 1973-83. They are as follows:

You could also use C30 mid '80's 1-ton springs, but I thought they would be too stiff. Those are:

Should help. Brought up the front end and leveled out mine.
