Rock Krawler 3in X Factor Suspension System - Stage 1

The Rock Krawler JT 3.0 inch X Factor Mid Arm System was specifically designed for those who want a complete bolt-in installation, maximum articulation from a mid-arm kit and the durability and off-road performance you expect from Rock Krawler Suspension. The X Factor Series adjustable lower control arms offer a total of 90 degrees of misalignment.

Rock Krawler’s industry leading triple rate coils give you 3 inches of lift and improves the on-road ride over the factory linear rate springs. All Rock Krawler JT systems includes two rear spring seats, as well as the corresponding two front spring pads. The provided track bar geometry corrections, both front and rear, lets you perfectly center the axles so there is no compromise in on-road handling.
