Rock Krawler 3.5" X-Factor X2 "No Limits" Long-Arm Suspension System for Jeep Wrangler JLU (Diesel Models)
The Rock Krawler Suspension 3.5" X - Factor X2 "No Limits" 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 Term, "No-Limits" comes from the inclusion of our front sway bar links specifically designed for use with the factory electronic sway bar disconnect feature found standard in your Rubicon Wrangler! The sway bar links themselves come with factory sized hardware, a CNC machined billet aluminum center section, and Made in USA heim joints from FK bearing, once installed, just press the button and hit the rocks!
The Rock Krawler X2 Longarm System features an Independent 3 link design front & rear for maximum articulation and off-road performance. 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 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.
We 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, our "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 lets you dominate the trails. When we design a system, our 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.
