73-80 GM P/U Radiator Support

The 73-80 GM P/U Radiator Support from Racing Power Co-Packaged is a bolt-on structural component specifically engineered for Chevrolet and GMC light-duty pickup trucks from the classic 1973–1980 model years. This essential frame-mounted assembly positions and secures the radiator assembly, protecting the cooling core from road debris and engine bay vibration while ensuring precise coolant flow pathways.

Manufactured from heavy-duty steel and finished to resist rust and corrosion, this radiator support features a rigid welded construction that maintains dimensional stability under thermal cycling and towing loads. It is designed to accommodate both original equipment radiator dimensions and modern aluminum cores, making it ideal for builders transitioning to high-efficiency cooling systems.

This component is essential for any C10, C20, K10, K20, or Blazer owner undertaking a cooling system refresh, frame-off restoration, or engine bay modification. Weighing 3.25 lbs, the support minimizes unsprung weight while providing the structural stiffness necessary to prevent radiator rattle and potential puncture failures that can compromise engine temperature regulation.
