I don't know if anyone else has had this problem, but my truck bounces a little bit as I go down the road, its because its a RCSB 4wd with Z71 package. I know it has Billstine shock in the back, but does anyone know a way to fix it without puting weights in the back? I am thinking about replacing the shocks? I like the rancho's that you can adjust for ride, but I don't know if that will fix the problem or not, suggestions???
