I currently have my bars adjusted 2 1/2 turns and I just ordered the Truxxx H3 Lift Kit. Should have it installed next week and I will provide feedback.

I just read the Truxxx report and while most of it is true that style of torsion key is not used in the H3. The H3 has a key bolt twice as big and doesn't force the end of the key up as in other gm's, It pulls the key down as you tighten the bolt. One thing I have noticed with the H3 is as you tighten the torsion bars the ride ends up getting rough...This is happening because the shock is "topping out". I cranked my torsion bars up 7 or 8 turns and untill my extended BDS shocks get here shimmed the shock lower in the mount so it is not "topping out. I also built a set of rear shackles that are 2 1/2 inches longer then stock to raise the rear and inch or so to match the front. In this pic I have the H3 with 315 Coopers, torsion bars cranked and shackles installed.
