20C WRANGLER JLU 4DR 4.5IN X FACTOR PRO ELITE ALUM SYS W/ PB+J LOWER MID ARMS

MIA's Description

The Rock Krawler 4.5" X-Factor PRO Elite "No Limits" Mid-Arm Diesel System is designed for Rubicon owners seeking a complete, bolt-in suspension system with superior articulation. It features lower control arms machined from 2" x 3" billet 7075 Aluminum, and other control arms from round 7075 Aluminum, all incorporating the X-Factor design. Adjustable upper and lower control arms with Pro-X Krawler Joints and Adventure Series joints offer 95 degrees of misalignment, reducing bind and allowing precise tuning of caster and pinion angles. "No Limits" front sway bar end links integrate with the factory Rubicon E-Disconnect for bind-free suspension travel. The system includes TRIPLE-RATE coils for excellent on-road comfort and off-road articulation, with correction pads to reduce spring bow. Track bar geometry corrections ensure perfect axle centering for optimal on-road handling. Designed for street, towing, and trail use.
