Description

The Rock Krawler 3.5 X-Factor Pro Elite Coilover Mid-Arm 4XE System is specifically designed for Rubicon owners who want a complete system, bolt-in installation, and the best articulation of any mid-arm kit on the market. It features lower control arms machined from 2 inch x 3 inch billet 7075 Aluminum, and four other control arms machined from round 7075 Aluminum with X-Factor built in. The system offers 95 degrees of misalignment with Pro-X Krawler Joints and Adventure Series joints, allowing precision tuning of caster and pinion angle. No-Limits front sway bar end links pair with factory Rubicon E Disconnect for bind-free suspension travel. The Comp System (Front Coilovers w/Rear Coil Combination) is ideal for those who want coilover performance upfront but still want to carry small loads or tow small trailers. Stage 1 features 2 5/8 RRD Racing Coilovers w/Remote Reservoirs up front and matching 2 5/8 RRD Racing Shocks w/Remote Reservoirs in the rear. Stage 2 includes Fast CD (Compression Dampening) Adjusters on coilovers and rear shocks for greater tuneability.
