If you run Dirt King upper control arms (UCAs) on your GM1500, Toyota, Lexus, or Ford truck, maintaining them is crucial for long-term performance. Over time, the rod ends (heims) and spherical bearings (uniballs) in your UCAs wear out, affecting handling, ride quality, and suspension articulation. Our Dirt King UCA Rebuild Kit is designed to restore your upper control arms to peak performance, ensuring durability and smooth operation.
