Chrysler PT Cruiser Coil Spring Isolator - Rear - Prothane - Black - 01-03. This direct-fit rear insulator replaces worn factory pieces to restore ride comfort and cut suspension noise on 2001–2003 PT Cruiser models.

Designed for the rear coil spring perch, it cushions the spring, reduces harshness, and limits metal-to-metal contact for a tighter, more controlled feel. Ideal for maintenance or mild customization, it helps maintain proper spring indexing and consistent ride height. Durable construction handles road grime, heat, and repeated compression, providing predictable performance for daily driving or weekend projects.
