Rear spring sag

Antman1984 · Oct 12, 2018

Hey guys I have a 74 with the duff 3.5 monster kit suspension lift. My driver side rear sits like 1.25" lower than the pass side. It drives me crazy when I look at it. I think it is just a weak spring on that side, but trying to avoid spending 500 on a pair of new springs. Any ideas?

I know it is a lot of work but you could swap the rear springs from one side to the other and see what happens.

Yea I need to put new shackle bushings in anyways.

That's a good first step. If they need new bushings, then that's the perfect time.
If the lean stays the same, then on to check the radius arm alignment.

And if nothing works (you did check the body mounts and all that, correct?) you can still add a lift block of the appropriate size to your low side leaf spring.

Are you sure it's a full 1 1/4 inches? Have you measured between the frame rail and the top of the axle tubes on both sides? Just curious, since that is a lot of lean and yes, would bug just about anybody.

Good luck.

I ended up putting a 1/2 inch steel shim under that spring and it is level now.
