Mopar Performance Coil Spring Insulator

The Mopar Performance Coil Spring Insulator (also called a spring isolator or coil spring isolator) is a suspension component that sits between the coil spring and its mounting seat. It cushions the contact between metal surfaces. This helps limit noise, vibration and harshness (NVH) from the suspension and supports a smooth, controlled ride.

Key Features:

• Isolates the coil spring from the spring seat or chassis mounting point to reduce metal-to-metal contact
• Helps dampen road noise and suspension vibration
• Supports correct spring seating and positioning for consistent suspension operation
• Backed by the Mopar brand, the source of factory-original and performance parts for Chrysler, Dodge, Jeep and Ram vehicles
• Direct-replacement design that installs at the original spring mounting location

Worn, cracked or compressed insulators can cause clunks, rattles and uneven spring seating. Replacing them when you service the springs or struts helps restore ride quality and quiet operation. Choose the correct part number for your application from the available options.
