Mopar Lower Coil Spring Isolator Seat

The Mopar Lower Coil Spring Isolator Seat (also called a lower coil spring insulator or spring seat isolator) sits between the bottom of the coil spring and the spring perch. It cushions the contact between the metal spring and the suspension mounting surface.

Key Features:

• Isolates the coil spring from the spring perch to help reduce noise, vibration and harshness
• Helps prevent metal-to-metal contact and wear at the spring seat
• Holds the lower end of the coil spring in position
• Genuine Mopar part, engineered to original equipment specifications

Replacing a worn, hardened or damaged isolator seat during suspension service helps restore the original ride quality and keeps the suspension quiet. Select the variant that matches your application from the options on this page.
