Rock Krawler 07-18 Jeep Wrangler JK 2DR / JKU 4DR Arm Pro Lower Long (PB+J) - Rear

Rock Krawler is known for making some seriously tough suspension components for off-road vehicles, and these rear lower long control arms for your 2007-2018 Jeep Wrangler JK and JKU are no exception. If you're looking to dial in your suspension geometry, especially after adding a lift kit, these arms are designed to help you achieve better alignment and improved articulation. They are built to handle the demands of serious off-roading while also providing a more stable ride on the street.

These are the long-arm version, meaning they replace your factory short arms with longer ones. This change in length helps to correct the caster angle, which is crucial for proper steering feel and stability, particularly with lifts over 3 inches. The 'PB+J' designation refers to Rock Krawler's specific joint system, which is designed for durability and flexibility. The joints are well-built to allow for the suspension travel you need off-road without binding, while also offering a degree of self-centering to help keep your Jeep tracking straight.

When you're installing these, you'll be replacing the stock lower control arms at the rear of your Jeep. This is a common upgrade for JK owners who want to fine-tune their suspension's performance, whether for rock crawling or just a more predictable feel on trails. Because these are longer arms, they can help improve the suspension's ability to cycle smoothly over obstacles, reducing the chances of binding and improving overall traction. It's a solid option for anyone serious about getting the most out of their JK's suspension setup.
