looking into a 4'' lift for my xj but im not real sure who has the "best" kit for what im looking for. This is my first time buying a kit instead of building a kit (like i did with the samis) Street manners is a big part and wheeling ability. Ive heard Rough Country's systems give a rough ride and they have terrible customer service. (hear say) Ive heard good things about Rusty's and Rubi Ex. but I want opinions from locals who have run different kits.
