The Rock Krawler Suspension 4.5" X - Factor X2 Long-Arm Diesel System is specifically designed for Wrangler owners who want to push their vehicle to its limits with hard core rock crawling. The Rock Krawler X2 Longarm System features an Independent 3 link design front & rear for maximum articulation and off-road performance. The 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 suspension provides adjustable anti-squat with "X2" rear suspension geometry with enhanced rear instant center(s) and rear roll center(s). As you drive the highways or the trails, the system feels stable, safe and strong whether you are running the stock drivetrain or pushing high horsepower through the chassis. They have built the X-Factor X2 system to be the toughest 3-Link setup on the market. At the frame connections of the lower control arms, the "Adventure Series" maintenance free joint is used to cut down on the amount of grease points and provide excellent vibration absorption and proper joint misalignment when off-road. The combination of high clearance long arms and 3 link suspension geometry let you dominate the trails. When Rock Krawler designs a system, their goal is to provide you with the most comprehensive solution and the best geometry, install exceptional value, and be the foundation for every adventure whether it be on the Street, In tow, or down a Trail! Thank you for considering Rock Krawler Suspension.

If building with a spare delete, we recommend dropping 1” in coil lift height for the rear.
If building an overland or heavily upfitted build in the back, we recommend upsizing 1” in coil lift height for the rear.
Recommend a new front C.V. driveshaft for all front shocks with max. extended length greater than 29"
