riding rough is not inherent with a jeep, only a jeep porely built. everything affects everything. anyone who points to one certain thing would be wrong. bolts, bushings, springs, shocks, wheelbase, etc etc. before spending money take the shocks off and see what it rides like. most all lift kit shocks suck. if it still rides rough then its time to work with bushings and springs. i disagree with most. i can get an awful spring to ride smooth even a rough country. anyone who takes a springpack out of the box and slaps it on as is, is selling himself short. ive got a set of BDS springs that are the worst by a far margin ive ever seen. i have a jeep on procomps and you can push down on the front bumper and it will sink several inches. it rides very smooth. the BDS equipped jeep i can jump up and down all day on the front and it wont budge. make sure your bushing system is designed not to bind and moves freely by hand even when torqued to factory specs. most if not all will nat be able to do this without some work. make sure you have the proper lube in them. some will cause premature hardeing and binding of the polyurethane. make sure the clamps on the leaves are not bend down tight from the factory. lubricate between the leaves. i use full length teflon liners.
