Replace the driver side (left) factory rear upper control arm mount with this Rust Buster OE-style repair part for the listed Chevrolet, GMC, and Cadillac applications. Heavy-duty 11-gauge steel provides the replacement mounting structure, and Class 10.9 upper arm mounting hardware is included. A load level sensor mounting hole and brake line pass-through retain provisions needed around the mount. Installation requires welding, and the fitment table separates the model-specific year ranges for accurate application checking.
