This is what I did. I flipped the main leaf, added 2 more leafs for a total of 3 leafs, plus the overload spring. Also running a 1" block. I have 1" of travel before it hits the frame rail.
Also I should add I used late 60"s VW Bug rear shocks on the rear, and Isuzu pickup shocks on the front. And this is as low as I could go without cutting something on the truck. The front is 3 splines on the torsion bars, and no bump stops on the front or rear.
Other than new short shocks, and the blocks, this was free.
