Rock Krawler 07-18 Jeep Wrangler JKU 4DR 3.5in X Factor System

Rock Krawler is known for building some of the most robust suspension components for serious off-road use, and their 3.5-inch X Factor System for the 2007-2018 Jeep Wrangler JKU 4-door is a prime example. This isn't just a lift kit; it's a complete system designed to improve your Jeep's capability both on and off the pavement, allowing for larger tires and better articulation.

This X Factor system includes a host of well-built components. You get front and rear adjustable control arms, which are crucial for properly aligning your axles after lifting the vehicle. The system also features front and rear sway bar disconnects, making it easier to gain maximum wheel travel when you're out on the trail. Heavy-duty track bars are included to keep your axles centered under the Jeep, and the system also incorporates a rear extended brake line to accommodate the increased suspension travel. Rock Krawler uses solid steel construction for these components, ensuring they can handle the stresses of off-road driving.

When installing a suspension system like this, it's important to have the right tools and a solid understanding of suspension geometry. You'll want to ensure all components are torqued to manufacturer specifications. This system is designed to work with your Jeep Wrangler JKU's factory mounting points, making installation as straightforward as possible for a lift kit of this complexity. It's a comprehensive package aimed at giving your JKU a significant boost in ground clearance and off-road performance.
