Rock Krawler ROCKZILLA Long-Arm Suspension Upgrade Kit for Jeep Wrangler JLU
The Rock Krawler Rockzilla System for the JLU is a state of the art suspension system designed for the ultimate in on road and off road capabilities. Rockzilla 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 apart from all the other systems on the market that are similar in style to Rockzilla is, Rockzilla 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 System in the JLU is second to none. Once installed, the JLU looks like it came from the factory with Rockzilla. Rockzilla sets up at approximately 4.5" of lift. Rockzilla is designed around axles that have a 70" WMS, wheels that have 3.5" of back spacing and 40" tall by 13.5" wide tires. 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 (518-270-9822). Lead times will apply.
