Rock Krawler 4. 5 Adventure X2 Pro Elite Coilover Long Arm Suspension System for Jeep Wrangler JLU (Gas Models) The Rock Krawler 4. 5 Adventure X2 Pro Elite Coilover Long Arm System is the ultimate in compromise between daily driver hard core off roader. The PRO Elite signifies you are entering the realm of PB&J (Pure Beef AND Jealousy) by purchasing a system that is outfitted with 4 Billet Aluminum CNC Machined Service Free lower control arms in a long arm length! This is as good as it gets; absolute strength, paired with a maintenance free peace of mind will have you blasting down any trail in America! The Adventure X2 systems combine the benefits of a full high clearance 4 link front suspension with a high clearance independent 3 link rear suspension. Say goodbye to greasing your joints, our service free long arm system is here to stay. In every single control arm, we have our Adventure Series joint center, which isolates harsh road vibrations equivalent to an OE bushing, includes high misalignment, and is fitted with a steel sleeve (that the bolt passes through) which rotates freely on a additional Teflon lined inner sleeve to insure that you are never chafing, twisting, or deforming the bushing material inside the housing as you blast through the mud, sand, sleet, salt, snow, dirt and dust. To finish it off, as you tighten your control arms into the mounts, the sleeve of the joint is engineered to be the buffer between the clamping force of a bracket, which means that as you tighten everything, you are not compressing the bushing. This all makes for an incredibly long lasting joint that never requires a drop of grease, and makes zero noise inside the housing. This is where conventional on road handling meets bad ass off road ability. With enhanced rear instant center (s) and rear roll center (s), X2 rear suspension geometry is the smoothest riding 3 Link suspension you can take down a trail or cruise across America in your Wrangler. The new high clearance axle mounts provide 4. 5 inch of ground clearance under the rear axle as compared to stock. The rear upper shock relocation brackets ensure you do not lose any shock or suspension travel. The combination of a full high clearance 4 link long arm front suspension and high clearance independent 3 link rear long arm suspension lets you dominate the streets and the trails. The front sway bar disconnects allow your suspension to work freely when you are offroad. The Comp System (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 Coilovers 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 Trail Runner System (Front and Rear Coilover Combination) is ideal for those that want the adjustability and performance of coilover racing shocks at all 4 corners. This combination maximizes the off road ability of your Wrangler and comes well tuned for the street. Rear coilovers 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!
