Wheel hop on my '94 Yukon 2Dr

[BradE]

Ok, I put some 20" USA Forged wheels on my '94 4x4 Yukon and needed to lift it approx. 2.5" to get clearance. Purchased a suspension lift with new torsion keys and blocks for the back leafs. Installed to specs, but now the front end is all over the place and bounces bad when I hit any little bump. I even installed new Rancho shocks for this truck in the front end, but not the back. The back already had brand new bilsteins installed 5,000 miles ago. I'm worried I'm going to ruin the front end if I keep driving it, so I'm looking for anyone with experience in this and the best way to fix it quick. Thanks for any and all replies!
