I have an 03 Tahoe 4wd , I lowered it with unknown trailblazer lowering springs and turned keys in front. As it is now it rides like ******, it sways really bad from side to side when riding over minor bumps. I have purchased the spohn panhard bar and shock extenders but have not installed yet. Any ideas on what makes it sway from side to side? It seemed to sway a little with eibach springs to , they just don't go low enough. As it sits now it's about 2" lower in front and 4-5" in rear. I will be doing free travel mod tomorrow as well as installing spohn panhard bar. Looks like someone changed shocks before I got it and put rancho shocks on it. Any recommendations on shocks from local parts stores I can use ?
