Rock Krawler 2018+ Jeep Wrangler JL 2DR / JLU 4DR Pro Lower Long Arm (PB+J) - Front

This kit includes the front Pro Lower Long Arm components from Rock Krawler, designed for the 2018 and newer Jeep Wrangler JL 2-door and JLU 4-door models. These long arms are a key part of a suspension upgrade aimed at improving articulation and on-road handling for lifted Jeeps. The PB+J designation refers to the specific joint technology used, which offers a balance of flex and durability.

Rock Krawler is known for building robust suspension parts, and this long arm kit is no exception. The arms themselves are constructed from solid steel tubing, chosen for its strength and ability to withstand the stresses of off-road use. The PB+J joints are a notable feature, allowing for greater movement than standard joints while maintaining good control. This setup is intended to work with a Rock Krawler suspension system, often paired with their adjustable track bars and sway bar disconnects to achieve optimal alignment and performance. Proper installation is crucial for these components to function as intended and to ensure vehicle safety and handling characteristics are maintained or improved.

When installing this front long arm kit, it's important to follow the manufacturer's detailed instructions. This typically involves removing the stock lower control arms and installing the new long arms, which are longer and mount to a different location on the frame. This geometry change is what allows for improved suspension travel and better caster angles, especially when the vehicle is lifted. Ensure you have the necessary tools and consider having a professional alignment performed after installation to dial in the suspension settings for your specific Jeep.
