Prothane 68-87 GM Small Block Radiator Insolators - Black

These Prothane radiator insuators are designed for 1968 through 1987 GM vehicles with small block engines. They help to isolate the radiator from the chassis, reducing vibration and noise that can be transmitted through the vehicle. This is a common replacement part when rebuilding or restoring a classic GM truck or car, especially if the original rubber mounts have degraded over time.

Made from durable polyurethane, these insuators are built to last. They replace the stock rubber bushings that often crack or crumble, offering a more solid and long-lasting solution. The black color provides a clean, understated look under the hood. Installation typically involves removing the old, worn-out mounts and installing these new ones in their place, helping to secure the radiator properly and absorb road shock.
