My SkyJacker 4. 5" is in need of some shocks, and maybe a bushing or 2. Perhaps I'm getting old but this thing rides like crap. Like I can feel every crack and crevice in the road. I'm not bouncing all over the place so I think the shocks aren't completely shot, and I'm not sure if I want to put any more money in it or return it to stock (with 2" level kit). Any suggestions?
