The Prothane radiator insulators in black are intended for 1988–1998 Chevrolet trucks with big block engines and act as cushioning pads between the radiator and mounting points. They reduce vibration transfer and help prevent metal-to-metal wear at the mount interface. These color-coded insulators serve as direct replacements to maintain radiator alignment and minimize noise from chassis vibrations.
