Mopar Performance Upper Coil Spring Isolator

The Mopar Performance Upper Coil Spring Isolator (also called an upper spring insulator or coil spring seat isolator) sits between the top of the coil spring and its mounting point. It keeps the spring seated and aligned. It also helps reduce noise, vibration, and harshness (NVH) in the suspension.

Key Features:

• Positions the coil spring at its upper mount so it stays aligned
• Isolates the spring from the chassis or strut mount to reduce road noise and vibration
• Built to Mopar specifications for fit, form, and function
• Designed to hold up to repeated compression cycles and exposure to the elements
• Fits the factory mounting points, so it works as a direct-replacement part

A worn, cracked, or compressed isolator can cause suspension clunks, rattles, and uneven spring seating. Replacing it restores factory-level ride quality and spring positioning. Choose the item in this product line that matches your application.
