JKU 4.5 Inch X Factor X2 Pro Elite Long Arm 4 Door Model

The Rock Krawler Suspension JKU Wrangler 4.5 inch X - Factor X2 PRO Long-Arm System is the ultimate in compromise between daily driver/hard core off-roader. PRO derives from having a set of PB&J (Pure beef and jealousy) Billet aluminum lower control arms. These arms are custom machined in-house, built using a solid square stock bar of billet aluminum and engineered to quite literally, handle any abuse you can throw at them. The X - Factor X2 systems combine the benefits of a full high clearance independent 3 link front suspension with a high clearance independent 3 link rear suspension. This is where conventional on road handling meets bad ass off-road ability. Our proprietary design utilizes a double adjustable front and rear upper control arm that upsizes the factory hardware to 14mm, 2 3/8" mounting width and 1" Pro Krawler joints at each end. The arm itself is a chromoly solid steel arm meant to carry all the forces of the suspension. The rear system uses our tried and true independent 3 link conversion with X2 rear suspension geometry with enhanced rear instant center(s) and rear roll center(s). The new high clearance axle mounts provide 3.5” 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 independent 3 link long arm front suspension and high clearance independent 3 link rear long arm suspension lets you dominate the streets and the trails.,/p>
