Prothane GM Radiator Support Bushings Small Block

Prothane GM radiator support bushings are polyurethane radiator insulators. They replace worn, cracked or collapsed factory rubber radiator mounts. They hold the radiator securely in place and help absorb vibration and road shock. They are also sold as radiator support insulators or radiator mount bushings.

Key Features:

• Polyurethane construction: Resists deterioration from oil, grease, road chemicals and weather. Original rubber tends to soften and break down with these.
• Better durability than rubber: Holds its shape over time, so the radiator stays supported and positioned.
• Vibration control: Cushions the radiator against engine and chassis movement, reducing stress on the core and mounting points.
• Direct-replacement design: Replaces the factory radiator support bushings, so installation is straightforward with basic hand tools.

Prothane specializes in polyurethane suspension and chassis bushings. This radiator support bushing line is a long-lasting upgrade over stock rubber for restoration, street and performance builds. Choose the variant that matches your application from the options on this page.
