The ICON Vehicle Dynamics Tubular Upper Control Arm (UCA) Kit is a critical suspension upgrade for the 2001-2010 Chevrolet and GMC 2500HD / 3500HD. These arms are engineered to correct front-end geometry and caster after lifting or leveling, ensuring the vehicle can be properly aligned to maintain factory-like handling. This kit replaces the weak factory ball joints with ICON’s patented Delta Joint, providing significantly more articulation and nearly 50% more wheel travel when paired with ICON performance shocks.
