Description

The Rock Krawler 2.5 Ultimate Adventure Mid-Arm System is engineered for Jeep Wrangler JLU 4XE owners seeking a complete, bolt-in suspension upgrade with exceptional articulation. This system is designed to enhance both on-road comfort and off-road performance through its durable construction and advanced components. It features 4 non-adjustable lower control arms and 4 fully adjustable upper arms, all equipped with 100% service-free Adventure Series joints that provide an impressive 70 degrees of misalignment. This design significantly reduces the inherent bind found in factory JLU control arms, optimizing suspension travel.
