I do not do any off roading. I just use the Jeep for pleasure riding on nice days. I don't mind a stiff ride as long as it does not toss me into the back seat as I am 66 years old.Check out any of the many posts in history and the result is the same. Stay away from Rough Country.
BDS, Rubicon Express (RE), Old Man Emu (OME) are the goto brands.
Tell us more of how you want the Jeep to ride, What you use it for, and budget. All will help you get what you want. There are also a few good custom builders Alcan and General Spring that are worth looking at, but I don't think they are as Jeep YJ saavy. JMHO.
