ACDelco Upper Coil Spring Insulator

The ACDelco Upper Coil Spring Insulator (also called a coil spring isolator or upper spring seat insulator) sits between the top of the coil spring and the vehicle's mounting point. It helps keep the spring seated correctly. It also helps isolate the chassis from road noise and vibration.

Key Features:

• Rubber isolator construction helps absorb vibration and reduce noise transmitted through the suspension
• Helps keep the coil spring properly positioned and supported
• Helps reduce metal-to-metal contact between the spring and the mounting surface
• Helps maintain a smooth, comfortable ride and consistent suspension performance
• Backed by ACDelco, a trusted name in replacement parts for domestic and import vehicles

Replacing a worn, cracked, or hardened insulator can help restore ride quality and reduce suspension noise. Installing new insulators when you replace springs, struts, or shocks is a common practice. Choose the specific part number in this product line that matches your application.
