first off, there is no such thing as a good ride quality for a modded cherokee. its bullsh/t and if anyone tells you different they are full of it. anytime you mod something, i don't care if its a freakin wheel chair its gonna ride different that what i did from the factory. so if you swap out stk for bigger coils and rear packs no matter what you think or spend its gonna be a different ride quality. period.
now, ive been running 6" SJ coils on my xj for five years. ive got acos set at min 1 1/4" on top and i love em. ive got the SJ 5" packs/1" shackles in back and after five years of beatings they are sagging but i don't baby my junk. after the first of the year im getting custom packs from national done cause im going bigger.
everyone that ive ever personally know, not second hand interweb bs has hated their rc lifts. ive seen coils sagging in a matter of months with lite wheeling. guess its just crappy materials, mfg, etc but ive never heard anyone 100% satisfied with a rc lift.
its not all about what ya spend. if your just getting sh/t to see red coils you should evaluate what your doing or just gets some rc's and get them powder coated and be a poser. no one says you have to get just one companies components either, i preach this all the time. you don't have to have just a SJ lift or rubicon express or so on. i got a smokin deal on my stuff back on 00 and its served me well but after repeated beatings im starting to part things out. after you wheel enough you'll grow out of components. i like my sj coils, will be replacing the rear packs, sometime next year im looking at a full traction set up to replace my SJ sub frame assembly as well. its been great im just looking to upgrade cause my wheeling style has moved from "ill do those 1 and 2 trails" to "sh/t its only a blk 4.5" and "sh/t its just a fender" "sh/t its just a rear door" and so on....
id say don't just get sh/t cause someone will think your cool, do your researching and talk to people in person with what your looking at buying. rather than a million opinions on the net you can actually see what that person runs and if they like it or not.
