Auto Metal Direct Radiator Mounting Panels

The radiator mounting panel is a crucial component that provides support and stability to the radiator in 1973-80 Chevy or GMC C/K pickup, Blazer, Jimmy, or Suburban models. This panel is located between the core support and the radiator—and is designed to ensure that the radiator stays securely in place while you're driving. Over time, the radiator mounting panel may become damaged due to exposure to the elements or from an accident, causing it to lose strength and stability. This can lead to the radiator shifting or bouncing while you're driving, which can result in serious damage to your engine. If you notice any signs of damage to your radiator mounting panel, it's important to replace it as soon as possible to avoid any potential problems. Auto Metal Direct radiator mounting panels are high-quality replacements for the original equipment on your vehicle. They're fabricated from steel with a protective black coating—and will provide the same level of support and stability as the factory part. The panels are also designed to be an exact fit for your vehicle, making installation quick and easy.
