Rock Krawler 07-18 Jeep Wrangler JKU 4DR 3.5in Adventure-X Pro Long Arm

The 3.5-inch lift height on this Rock Krawler Adventure-X Pro Long Arm system is achieved using a combination of progressive rate front springs and rear springs, paired with adjustable front and rear shocks. This setup is specifically designed for the 4-door Jeep Wrangler JKU models from 2007 to 2018, aiming to improve both on-road comfort and off-road capability. The long arm geometry is a key feature, intended to correct suspension angles and provide a more stable, predictable ride, especially when tackling challenging terrain or carrying extra weight.

Rock Krawler utilizes heavy-duty, fabricated steel components throughout this kit. The control arms are built with robust materials and feature adjustable heim joints, allowing for precise alignment tuning to match your specific driving needs and tire size. This adjustability is crucial for optimizing caster and camber, which directly impacts steering feel and tire wear. The system also includes a front track bar relocation bracket and a rear track bar, ensuring proper axle centering under the lifted vehicle. This attention to detail in geometry correction helps prevent common issues associated with lifting a Jeep, such as wandering or poor handling.

Included in this comprehensive kit are all the necessary components for a significant suspension upgrade. You'll find front and rear springs, adjustable shocks, front and rear long control arms, a front track bar relocation bracket, a rear track bar, and all the required mounting hardware. This system is engineered to accommodate larger tires, typically up to 37 inches, allowing for greater ground clearance and off-road performance. While this is a complete system, always refer to the manufacturer's installation instructions for specific details on torque specifications and any additional components that may be recommended for your build.
