Rock Krawler 2021+ Jeep Wrangler JLU 4DR (392) 4.5in X Factor (No Limits) System

This Rock Krawler X Factor (No Limits) System for your 2021 and up Jeep Wrangler JLU 4-door, specifically the 392 model, gives you a 4.5-inch lift. What you get in this comprehensive package includes a full set of Rock Krawler's X Factor adjustable control arms, which are built for serious off-road use. It also includes the necessary shocks to complement the lift height, along with all the brackets, hardware, and sway bar links needed for a complete installation. This system is designed to provide improved articulation and ground clearance, making your Wrangler more capable when you take it off the pavement.

The X Factor control arms are a standout feature here. They're constructed from solid 1.75-inch OD x 0.375-inch wall DOM tubing, which is a very strong material that can handle the stresses of off-roading. These arms are fully adjustable, allowing you to fine-tune your suspension geometry for optimal alignment and performance, especially after a significant lift. The system also incorporates Rock Krawler's sway bar disconnects, making it easier to get maximum flex on the trail. The included shocks are chosen to work in harmony with the lift and control arms, providing a balanced ride both on and off-road.

When installing a system like this, you're looking at a significant suspension overhaul. It's a good idea to have a solid understanding of suspension components or to work with a trusted mechanic. Having the right tools, including a torque wrench and potentially a spring compressor, will be essential. This system is designed to be a complete solution, so you can expect everything you need for the lift and suspension geometry correction to be included in the box, allowing you to get your JLU ready for adventure.
