The Rock Krawler Rockzilla Lite System for the JLU is a state of the art suspension system designed for the ultimate in on road and off road capabilities. Rockzilla Lite features an independent 3 link front suspension with a double triangulated rear suspension. Instant centers and roll centers have all been greatly improved. What sets Rockzilla Lite apart from all the other systems on the market that are similar in style to Rockzilla Lite is, Rockzilla Lite requires absolutely no cutting holes in the tub for suspension mounting points or fuel cell relocation. There is no driving around smelling fuel inside the vehicle nor worrying about how to seal up the tub from the elements. This is a huge benefit to those looking to have an aggressive off road vehicle but maintaining civility inside for driving comfort. This is accomplished by incorporating a center mounted fuel cell that improves the vehicles center of gravity, rear double triangulated cross member and skid plate system for a perfectly smooth bottom in a JLU. The packaging of the Rockzilla Lite System in the JLU is second to none. Once installed the JLU looks like it came from the factory with Rockzilla Lite. Rockzilla Lite features massive 13" Travel 2 5/8 RRD Remote Reservoir Racing Coil Overs up front, 12.5" Travel 2 5/8 RRD Remote Reservoir Racing Shocks in the rear paired with tuned triple rate coil springs. Rockzilla Lite sets up at approximately 4.5" of lift. Rockzilla Lite is designed around axles that have a 70" WMS minimum, wheels that have 3.5" back spacing and 40" tall and 13.5" wide tires or functional equivalent. Once installed your JLU will become an off road Monster! Slight customization of the system is available for power train changes other than stock 2.0T and 3.6L V6 applications. Please discuss all your particular needs with a Rock Krawler Technician prior to order. Lead times will apply.
