Rock Krawler 4.5" ROCKZILLA COILOVER Long-Arm Suspension 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 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 sets up at approximately 4.5" of lift. Rockzilla 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 (518-270-9822). Lead times will apply.

The LITE (Front Coilovers w/ Rear Coil Combination) is ideal for those that want the adjustability and performance of coilover racing shocks up front, but still want to use their Wrangler to carry small loads or tow small trailers. There are two options for the Comp Systems you can choose from. The standard or Stage 1 System features 2 5/8" RRD Racing Coil Overs w/ Remote Reservoirs up front paired with matching 2 5/8" RRD Racing Shocks w/ Remote Reservoirs in the rear for a well tuned package. Or you can opt for the Stage 2 Comp System which will include Fast CD (Compression Dampening) Adjusters on the coilovers and rear shocks for an even greater level of tuneability.

The ROCKZILLA (Front and Rear Coilover Combination) is ideal for those that want the adjustability and performance of coil over racing shocks at all 4 corners. This combination maximizes the off road ability of your Gladiator and comes well tuned for the street.  Rear coil overs perform amazing off road, but do not take changes in loading conditions too well so towing or adding a lot of weight to the bed area is not optimal for rear coilovers. The standard or Stage 1 System features 2 5/8" RRD Racing Coilovers w/ Remote Reservoirs front and for a well tuned package. Or you can opt for the Stage 2 Trail Runner System which will include Fast CD (Compression Dampening) Adjusters on the coilovers for an even greater level of tuneability. 

Like all of our systems, amazingly tuned ride and handling is our number one priority! It is no different with our coilover systems. Coilovers add another level of tuneability for the vehicle owner to further enhance the ride, handling and off road performance to their liking. Install exceptional value, and be the foundation for every adventure whether it be on the Street or on the Trail with a Rock Krawler Coilover Suspension System! Thank you for considering Rock Krawler Suspension.
