Prothane 7-1706-BL Rear Upper Coil Spring Isolators GM 1965-1995

The Prothane 7-1706-BL rear upper coil spring isolators are designed to replace worn or deteriorated factory rubber isolators on GM vehicles from 1965 to 1995. These high-performance polyurethane isolators provide superior durability and maintain consistent coil spring positioning for improved suspension performance.

Key Features:

• Manufactured from durable polyurethane material that resists deterioration, cracking, and compression
• Direct replacement for original equipment rubber isolators
• Maintains proper coil spring alignment and reduces unwanted spring movement
• Reduces squeaks and noise associated with worn rubber isolators
• Blue polyurethane construction for easy identification during installation
• Includes grease for proper installation and break-in

Prothane's polyurethane formulation offers significantly longer service life compared to original rubber components while providing better suspension feedback and handling characteristics. These isolators help restore proper suspension geometry and eliminate the sloppy feel caused by worn factory parts.
