This is a great full suspension system for the XJ Cherokee that gives you 4.5" of lift and has everything you need to maintain proper suspension geometry. It includes new HD lower control arms that have soft ride rubber bushings at both ends that not only give you great flex but do an awesome job of absorbing road noise for a nice quiet ride. The front coil springs have a perfectly engineered spring rate that not only give you full articulation off road but also provide for a very stable handling suspension on road. These are matched with performance shocks that have valving designed to work perfectly with the coils to give a superb on and off-road ride.
The rear suspension utilizes a full length leave that installs under the main leaf of your factory leaf springs. These give additional arch to the factory leafs and are designed to perfectly increase their spring rate. These are used in conjunction with longer shackles that give the additional lift height and allow for full articulation. The benefit to using a longer secondary leaf along with a longer shackle, as apposed to using a full replacement lift spring is that you get more articulation and a much softer ride. Simply using an aftermarket leaf spring with the shorter factory shackle would give too stiff of a ride and would not provide full articulation.
The system includes all necessary hardware for installation, leaving for an easy bolt on install with basic hand tools. The system comes with grade 8 replacement leaf spring u-bolts, brake line extension hardware, HD shock pins, and longer front sway bar links with polyurethane bushings. You won't find a better performing 4.5" XJ lift kit with quality components for the money.
