Detailed Description

This Westar coil spring insulator, part number ST-7993, is a suspension component used in rear upper fitments on the Chrysler Sebring, Dodge Stratus, Dodge Avenger, Mitsubishi Eclipse, and Mitsubishi Galant. Its function is to reduce noise and vibration transfer while helping the suspension maintain proper operating dynamics. For buyers searching for a Westar ST-7993 replacement or a coil spring insulator for Chrysler Sebring rear upper suspension service, this part addresses a common wear point in the spring and strut assembly.

Westar positions this product line around application-specific materials and a protective finish that supports longer service life. The design also serves as a pivot point for suspension rotation, which helps preserve steering feel and reduce uneven tire and component wear. If you are replacing a worn ST-7993 insulator on a Dodge Stratus or Mitsubishi Eclipse, matching the listed position is important for correct installation and function.

What It Is Used For

• Eliminating squeaks, rattles, and vibration from worn suspension isolation parts.
• Restoring proper spring seating and suspension movement.
• Reducing metal-to-metal contact in the strut assembly.
• Addressing looseness or noise in rear upper suspension service.

Installation Notes and Tips

Verify the vehicle year, make, model, and rear upper position before installation. Compare the removed part to the new ST-7993 coil spring insulator to confirm shape and mounting points. Because this part works within the suspension assembly, inspect related components for wear during service and replace any damaged parts as needed.
