Spring forensics

[N2TRUX]

Lets start by clarifying the lean. Almost every 73-87 GM truck that left the GM plant had a lean of some sort. The later years "seem" to be less, but it was still common.

With that clear, I feel your issue was compounded by a spring that was improperly seated. If it were me, I would cut half a coil and see what happens. If you seat them properly and still have some lean, cut a 1/4 turn less on the low side and try again.

The concern over advertisers saying 1-2-3" of drop addresses the issue of springs being old and sagging. If you have a set of really worn spring and add an aftermarket lowering spring you might only see 1 or 2" of drop. If you have springs that haven't sagged much you might get a full 3" of drop.

My experience has been it's better to cut a spring in smaller increments to get the the drop you want. It requires more work, but its a lot easier than trying to add a piece back on the end of a spring thats cut too much.
