Rock Krawler 2021+ Jeep Wrangler JLU 4DR (4XE) 4.5in X Factor Pro Aluminum System

Built from solid 7075-T6 aluminum, this Rock Krawler X Factor Pro system is designed to give your 2021 and newer Jeep Wrangler JLU 4-door, including the 4XE model, a 4.5-inch lift. This material choice is notable because it's strong and lightweight, which helps maintain your Jeep's on-road handling characteristics while providing the durability you need off-road. The system is engineered to work with the factory electronic sway bar disconnect, making it a practical choice for those who want to retain that feature.

The X Factor Pro system includes a range of components aimed at improving your Jeep's suspension performance. You get adjustable control arms, which allow for fine-tuning of caster and pinion angles after the lift is installed, ensuring proper alignment and drivability. The system also incorporates a front track bar relocation bracket and a rear track bar, keeping your axles centered under the body for stable handling. Rock Krawler is known for its well-built suspension components, and this system reflects that reputation with its robust construction and thoughtful design for the specific needs of the JLU platform.

When installing a suspension lift of this magnitude, it's important to consider other components that might be affected or are necessary for a complete setup. While this kit provides the core suspension lift, you may need to address brake line extensions, exhaust modifications, or driveshaft angles depending on your specific Jeep and intended use. Always refer to the manufacturer's installation instructions for a detailed guide and a complete list of recommended or required additional parts to ensure a safe and proper installation.
