Prothane 68-87 GM Small Block Radiator Insolators - Red

Prothane radiator insuators are designed for 1968 through 1987 GM vehicles with small block engines. These insuators are made from a durable red polyurethane material that helps absorb engine vibration, reducing noise and preventing stress on your radiator and mounting hardware. They are a popular choice for classic truck and car builds, like a 1975 Chevrolet C10 or a 1972 Chevrolet Chevelle, where reducing unwanted noise and vibration is key.

These insuators replace the stock rubber or plastic bushings that often degrade over time. The polyurethane construction offers improved resistance to heat and chemicals compared to rubber, ensuring a longer service life. Installation is straightforward, typically involving removing the old, worn-out bushings and pressing in the new Prothane units. This is a simple way to improve the overall feel of your classic vehicle.
