Rock Krawler 2018+ Jeep Wrangler JL 2DR 4.5in X Factor X2 Long Arm Suspension - Stage 1

This Rock Krawler X Factor X2 Long Arm Suspension System for your 2018 and newer 2-door Jeep Wrangler JL gives you a 4.5-inch lift, designed to significantly improve your off-road capability. This Stage 1 kit is the foundation for a serious suspension upgrade, focusing on the core components that change your Jeep's geometry for better articulation and on-road manners.

The X Factor X2 system utilizes long-arm technology, which means longer control arms that mount lower on the frame. This setup provides a more natural suspension arc, allowing for greater wheel travel and improved articulation over obstacles. The kit includes Rock Krawler's proprietary X Factor adjustable lower control arms, which are built from solid 1.75-inch OD x .375-inch wall DOM tubing for exceptional strength. These arms feature Rock Krawler's R-Flex™ adjustable control arm joints, offering a wide range of motion and durability. You also get the necessary mounting brackets and hardware to integrate these long arms into your Jeep's chassis. This system is designed to work with your Jeep's factory transfer case, but it's recommended to pair it with an aftermarket driveshaft for optimal performance and to prevent binding, especially at full suspension compression.

Installing a long-arm suspension system is a significant undertaking that requires careful attention to detail. While this kit is designed to be a bolt-on installation, it does involve modifying your Jeep's frame to mount the new brackets. It's a well-built system that transforms your JL's suspension geometry, offering a noticeable improvement in both off-road performance and on-road comfort compared to stock or basic lift kits. For the best results and to ensure proper alignment, professional installation is often recommended.
