softening up my ride

99 XJ 4.0 AX15 about 5 inches of lift

My Cherokee has about 5 inches of lift it currently has rusty's shocks and a 6 leaf pack in the rear it does great in turns and ive put car trailers with cars on the back and have gotten very little saggage but it rides like a brick would a different set of shocks like skyjacker N9000's soften it up a little bit? i would do a 5 leaf pack but i tow/haul alot.

i would first investigate the angles associated with your control arms and shackles. getting those set properly will help more than you might imagine.
