Rock Krawler 2020+ Jeep Wrangler JLU 4DR (Diesel) 3.5in X Factor System

The X Factor System from Rock Krawler is built around a set of heavy-duty, adjustable control arms. These arms are constructed from solid 1.75-inch OD x 0.375-inch wall DOM tubing, which is a strong material that can handle the stresses of off-road driving. This system is specifically designed for the 2020 and newer Jeep Wrangler JLU 4-door models equipped with the diesel engine, offering a 3.5-inch lift to accommodate larger tires and improve ground clearance.

Rock Krawler's X Factor System includes their proprietary Pro-Ride coil springs, which are engineered to provide a comfortable ride on the street while maintaining excellent performance when you leave the pavement. The system also features adjustable track bars and sway bar disconnects, allowing you to fine-tune your suspension geometry for optimal handling and articulation. The adjustable control arms are a key component, enabling you to correct caster and pinion angles after the lift is installed, which is crucial for proper driveline operation and steering stability.

Installation of this system is a significant undertaking, often requiring specialized tools and a good understanding of suspension components. It's designed to be a comprehensive upgrade, and while it includes many of the necessary parts for a complete lift, it's always a good idea to consult the manufacturer's installation guide for a detailed list of all required hardware and recommended procedures. This system is a solid option for those looking to significantly enhance their Jeep's off-road capability and on-road manners.
