Description

The Rock Krawler 4.5" X-Factor COILOVER Mid-Arm System is specifically designed for Sport and Sahara owners who want a complete system, bolt-in installation, and the best articulation of any MID-ARM kit on the market. It features industry-leading X-Factor Series adjustable upper and lower control arms with Pro-X Krawler Joints and Adventure Series joints, offering 95 degrees of misalignment to reduce factory JL control arm bind. The system allows precision tuning of caster and pinion angles front and rear. Provided track bar geometry corrections ensure perfectly centered axles for uncompromised on-road handling. The Comp System (Front Coilovers w/ Rear Coil Combination) is ideal for those who desire the adjustability and performance of coilover racing shocks up front, while retaining the ability to carry small loads or tow small trailers. This Stage 2 Comp System includes Fast CD (Compression Dampening) Adjusters on the coilovers and rear shocks for enhanced tunability. The system provides an amazingly tuned ride and handling, along with an additional level of tunability for vehicle owners to further enhance ride, handling, and off-road performance.
