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

Built with 1.75-inch OD x 0.250-inch wall DOM tubing, these rear lower control arms from Rock Krawler are made to handle the demands of a modified Jeep Wrangler JK. They are designed to correct suspension geometry, especially when lifting your vehicle, helping to improve caster and pinion angles. This is crucial for maintaining proper alignment and ensuring your Jeep drives predictably on and off-road.

The PB+J (Pro Built and Joint) system incorporates a combination of a high-misalignment spherical bearing on one end and a durable, serviceable Pro Joint on the other. This setup allows for a wide range of motion while also providing the strength and longevity needed for serious off-road use. The DOM tubing offers a strong foundation, resisting bending and damage from impacts. These arms are a substantial upgrade for any JK owner looking to fine-tune their suspension after a lift kit installation.

When installing these longer control arms, you'll want to ensure you have the necessary tools and a clear understanding of suspension alignment. Proper installation is key to realizing the full benefits of the corrected geometry. It's a good idea to have your alignment checked by a professional after installation to confirm everything is set to manufacturer specifications for your specific lift height.
