correct, those screws will twist the torsion keys and load up the bars, this will bring just the front up. Too far will cause problems though with weaing out steering and suspension parts much faster.
The rear is lift blocks. Summit racing or jeggs is where I would start prices are good.
On my tahoe currenty I have the Kumho road venture MT (35x12.5) wheels are 17x9 atx artillery. Suburban runs a BFG AT (35x12.5) on a 17x8 ATX mojave.
The set up in my sig is a 17x8 mojave with a Procomp extreme AT 35x12.5
So what would you say is good to twist those torsion keys? 2inch should be the max? I really don't want to start replacing steering and suspension parts.. do you recommend this route or should I just buckle up and do the full suspension lift?
The problem with body lifts is the gap! for example:
Is there anyway to avoid this? or is this one this bad cause is more than 3inch?
