I'm trying to fully understand what will happen when I install lowering keys. I'd like to bring down the front of my '97 K2500 about 2". But if I have it right, the torsion bars will pretty much stay the same distance from the ground, but the frame will drop toward them. Unfortunately it looks like there's not much more than 1" clearance between the frame and the bar right now. Is there something else that happens that would allow the frame to get lower? Thanks...
