Prothane 7-1712 Radiator Support Bushings GM Big Block 1968-1987

The Prothane 7-1712 radiator support isolator kit provides a durable polyurethane upgrade for GM big block applications from 1968 to 1987. This four-piece kit replaces the factory rubber radiator mounting bushings with Prothane's high-performance polyurethane compound, ensuring long-lasting support and vibration isolation for your radiator.

Key Features:

• Four-piece complete radiator isolator/bushing kit
• Manufactured from Prothane's proprietary polyurethane compound
• Resistant to chemicals, oil, road salt, and weather elements
• Will not crack, harden, or deteriorate like original rubber bushings
• Direct replacement for worn or damaged factory radiator mounts
• Maintains proper radiator positioning and prevents excessive movement
• Designed specifically for GM big block engine applications

Unlike stock rubber isolators that deteriorate over time from engine heat and chemical exposure, these polyurethane bushings maintain their integrity and performance for years. This kit is ideal for restoration projects, performance builds, or simply replacing worn original equipment to prevent radiator damage and ensure proper cooling system alignment.
