Product Details
Rock Krawler is known for building some of the most robust suspension systems out there, and this X Factor X2 Long Arm system for the 2021 and up Jeep Wrangler JLU 4-door, specifically the 392 models, is a prime example. If you're looking to significantly upgrade your Jeep's off-road capability and on-road manners, especially for serious trail use, this kit is designed to make a big difference. It's engineered to provide 4.5 inches of lift while incorporating their advanced long-arm geometry, which helps to correct suspension angles and improve articulation.
This X Factor X2 system is built around Rock Krawler's durable components, including their stout long-arm brackets and heavy-duty control arms. The 'No Limits' designation means this kit is designed for maximum travel and articulation, allowing your tires to stay planted on uneven terrain. The long-arm setup moves the mounting points of the control arms further back on the chassis, which creates a more optimal angle for the arms and allows for greater suspension droop and compression. This translates to a more comfortable ride on rough trails and better control when you're pushing your Jeep to its limits. The kit is specifically tuned for the heavier 392 models, ensuring proper spring rates and damping characteristics to handle the extra weight.
When installing a system like this, it's important to understand that it's a comprehensive upgrade. The kit includes the necessary long-arm components, brackets, and hardware to transform your Jeep's suspension. While it's designed to integrate with your existing chassis, professional installation is recommended due to the complexity and the critical nature of suspension geometry. This system is a significant investment in your Jeep's off-road performance, offering a well-built solution for those who demand the best from their vehicle on challenging terrain.
