Torsion bar factory setup?

[stutaeng]

Hey guys, can anyone direct me to the source of the factory torsion bar set up for GMT-400 trucks? Namely, the "Z" dimension. I'm going to be rebuilding the front end of my K3500 soon. Is the setup the same for all the K-series? I've got the forged LCA if it matters.

The Haynes manual has a figure with the "Z" dimension for the GMT-800 trucks, but the manual for GMT-400 does not. I'm going to be buying that OTC torsion bar unloader because I also want to restore the factory ride height on my 06 suburban. The PO cranked the torsion bars to "leveled."

Here it is. The reference to 10906 and 20906 is a 1/2 and 3/4 ton Suburban.

If you change the ride-height, don't forget to aim the headlights, too.

Does this apply to any gmt400 1/2 ton?
