Product Details
This is the Rock Krawler rear upper box kit for the 2007-2018 Jeep Wrangler JK, specifically designed for the 4.5 AX/X2 suspension system and a 6-inch rear stretch. This kit is a key component for serious off-road builds, allowing for significant suspension travel and articulation by reinforcing the frame where the upper control arms mount. It’s built to handle the stresses of extreme articulation and off-road abuse, ensuring your suspension stays connected and controlled when you need it most.
Rock Krawler is known for making well-built suspension components for Jeeps, and this box kit is no exception. It’s constructed from solid steel, providing a strong foundation for your rear upper control arms. The design accounts for the extended wheelbase achieved with a 6-inch rear stretch, which helps improve stability and traction on uneven terrain. Installing this kit involves welding to the frame, so it's a job for someone comfortable with fabrication or a professional installer. Proper installation is crucial for the integrity and performance of your suspension system.
When you're pushing your JK's suspension to its limits, especially with a significant rear stretch, reinforcing the frame is essential. This kit addresses that need directly, offering a robust solution for mounting your rear upper control arms. It's a critical piece for anyone looking to maximize their Wrangler's off-road capability and durability.
