Anyone running a Superlift?

[Smallz72project]

I've got a 99 Gmc with the 6.5-7.5 in Superlift. It is a dual shock design, and the lower shock bushings are shot, but other then that everything looks to be in proper spec and working order. However something is just off with it, occasionally it feels like the front shifts from side to side and at times has an extremely bad death wobble. The torsion bars are maxed out yet the truck is not sitting level from side to side nor front to back. Just wondering if anyone else running this lift has had similar problems and what actions were taken to correct it.

So far I am not impressed with the setup. I am going to replace the shocks, get heavier duty torsion bars, install a steering stab. and also put ladder bars on the rear. It also has a three inch body lift, so I am going to put a Borgenson steering shaft with a vib. dampener. on it. If that doesnt seem to fix the situation I'm thinking about removing the lift and installing a Fabtech. But wanted to get some advice before I drop a ton of money into it for no apart reason. Thanks in advance guys. Keep truckin
