Overview

Westar ST-3909 is a suspension strut mount for select Mazda Protege applications. It is built to provide a stable mounting point for the strut while helping isolate road noise and vibration.

Fits 1995-1998 Mazda Protege, rear left. Part number ST-3909 is also referenced by several aftermarket brands for the same application.

Key Features

  • Provides a pivot point that supports proper suspension movement and steering response.
  • Locks the strut and body together for secure mounting.
  • Includes a noise-dampening design to reduce road vibration transfer into the cabin.
  • Made with materials selected for the application and finished to help extend service life.

Detailed Description

This Westar suspension strut mount is engineered for the rear left position on 1995-1998 Mazda Protege models. As a strut mount, it helps connect the strut assembly to the body while allowing the suspension to rotate as needed during normal operation. That function supports consistent suspension geometry and helps reduce uneven tire and component wear. The ST-3909 is a practical replacement choice when the original mount shows wear, noise, or reduced isolation performance.

Westar ST-3909 cross-references Monroe Shocks & Struts 903909 for the same application.

What It Helps Address

  • Clunking or knocking from a worn strut mount.
  • Excess road noise and vibration entering the cabin.
  • Loose or unstable strut-to-body mounting.
  • Suspension movement that no longer tracks smoothly.

Installation Notes and Tips

Verify the rear left fitment before installation on your Mazda Protege. Inspect the surrounding suspension components, including the strut assembly and related mounting points, for wear or damage before replacing the mount. Confirm that the replacement matches the vehicle position and application details listed for ST-3909.

Quality Assurance

Westar states that this mount uses high-quality materials and a protective finish intended to improve appearance and help extend service life.
