My 99 ECSB Z71 is pretty low (compared to newer Z71s) even with 265x75r16 rubber. However, I've got the classic 2" lift block and two leafs/overload rear setup. Between the long leaf springs, lack of leafs, and the block I get a lot of wrap. And the rear is 1 3/8" higher than the front.
So, the plan is to remove the block and crank down the torsion bars. But, how much cranking can I get out of those torsion bars? Currently, the adjusters are threaded in about 2/3.
The GM part number for factory U-bolts on a 2wd 1/2 ton appear to be #15002781. Anybody happen to know the dimensions? I live in BFE.
Next, will factory length 4x4 shocks be short enough to deal with the 1.25" shorter overall shock length? It looks like it but I don't want to bottom out and tear off the girly bracket on the chassis.
I don't want to go too low as we see around 300" of snow each year here and the 12' of wheelbase already makes it a bit of a chore. I'm mostly out to level it and get a little better ride quality/stance with pipedreams of better fuel economy. It'd be nice to close the gaps in the wheelwells also since there is such limited wheel travel on these trucks but I'm not too worried about that. I have bags to keep it off the bumpstops when towing.
The truck tows a slightly modified version of this on a 20' car hauler periodically so putting it on the ground is not an option:
