Dorman Suspension Coil Spring Insulator

The Dorman Suspension Coil Spring Insulator (also called a coil spring isolator, spring seat insulator or spring pad) helps cushion the coil spring where it meets the spring seat in the suspension. It is a replacement part for worn, cracked, hardened or missing insulators.

Key Features:

• Isolates the coil spring from the mounting surface to help reduce noise, vibration and harshness
• Helps prevent metal-to-metal contact between the spring and the seat, which can cause squeaks and clunks
• Made from durable rubber or similar resilient material to hold up to road conditions, temperature changes and ongoing suspension movement
• Helps the spring sit correctly for steadier ride quality and handling
• Designed as a direct replacement for the original insulator
