The Rock Krawler upper control arm is intended for 2020+ Jeep Wrangler JLU four‑door vehicles using a 4.5in X Factor X2 (No Limits) long‑arm suspension. It replaces the factory upper arm geometry to suit long‑arm travel and intended suspension articulation, serving as a key alignment and control link within the No Limits kit. Install with matching hardware and set alignment per Rock Krawler specifications.
