Mazzulla Offroad

If you run Mazzulla Off-Road 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 Mazzulla Off-Road UCA Rebuild Kit is designed to restore your upper control arms to peak performance, ensuring durability and smooth operation.
