Unless your gonna do some serious wheelin get the hydraulic shocks. I got a set of nitro shocks with my Rough Country 4 inch lift kit and there wicked bouncy. like riding on a balloon. I think the hydr. units would be smoother. Also they said to scrap the boots, they just hold the crap in the boot and it sits there attacking the rod. If it's not there the stuff is easy to wash off.
