Rock Krawler 2020+ Jeep Wrangler JLU 4DR 4.5in X Factor Pro Aluminum System

This Rock Krawler X Factor Pro Aluminum System gives your 2020 and newer 4-door Jeep Wrangler JLU a 4.5-inch lift, transforming its off-road capability. You get a complete package designed to handle demanding terrain, featuring a host of well-built aluminum components that reduce unsprung weight for improved suspension response. This system is engineered to provide a significant increase in ground clearance and suspension travel, allowing for larger tires and more aggressive off-road adventures.

The X Factor Pro Aluminum System is built with Rock Krawler's signature attention to detail. It includes their Pro Control Arms, which are crafted from high-strength aluminum for a strong yet lightweight setup. These arms are designed to correct caster and pinion angles after the lift, ensuring proper driveline geometry and improved on-road manners. The system also incorporates adjustable track bars to center the axles, preventing steering wheel shimmy and ensuring the vehicle tracks straight. Heavy-duty sway bar links are included to maintain proper sway bar geometry at the increased ride height, contributing to safer handling. The aluminum construction not only shaves weight but also offers excellent resistance to corrosion, making it a durable choice for off-road use.

When installing this system, you'll want to ensure you have the necessary tools for a comprehensive suspension overhaul. It's recommended to have a torque wrench to tighten components to manufacturer specifications. Because this is a significant suspension modification, it's also wise to consider upgrading your shocks and potentially your brake lines to match the new ride height and intended use. Rock Krawler's systems are known for their bolt-on nature, minimizing the need for welding or cutting, but always refer to the manufacturer's installation instructions for the most accurate guidance.
