Jeep JLU 4.5" X-Factor 392 Mid-Arm "No-Limits" System

The Rock Krawler Suspension JLU 4.5 inch X-Factor 392 "No-Limits" Mid-Arm System is a game-changer for Wrangler 392 owners seeking a comprehensive, bolt-in suspension solution. This system is designed to provide the best articulation and off-road performance on the market, thanks to its innovative features and durable construction. The "No-Limits" name is a testament to the system's ability to tackle any terrain with ease, thanks to the inclusion of specially designed sway bar links that work seamlessly with the factory electronic sway bar disconnect feature in the Rubicon Wrangler.

Key Features and Benefits

This system boasts an array of features that set it apart from other mid-arm kits. The X-Factor Series adjustable upper and lower control arms offer a total of 95 degrees of misalignment, significantly reducing factory control arm bind. This, combined with Pro-X Krawler Joints and Adventure Series joints, allows for precise tuning of caster and pinion angle front and rear. The system also includes Triple Rate coils for a comfortable on-road ride, while maintaining exceptional off-road articulation. Other notable features include spring correction seats, vehicle lean correction, and the ability to upgrade to the RK Longarm System. With Rock Krawler's industry-leading technical support and lifetime warranty coverage, you can trust that this system is built to last and backed by a company that stands behind its products.

Complete System and Installation

The Rock Krawler JLU 4.5 inch X-Factor 392 "No-Limits" Mid-Arm System includes everything needed for a complete installation, including front and rear adjustable control arms, sway bar links, track bars, and spring pads. The system is designed for easy bolt-in installation, making it accessible for both DIY enthusiasts and professional installers. With this system, you can expect improved rear roll center, enhanced on-road handling, and the ability to fit a variety of wheel and tire combinations. Whether you're driving on the streets, towing, or hitting the trails, this system is the foundation for every adventure, providing the ultimate combination of comfort, performance, and reliability.
