Westar ST-1921 Suspension Strut Mount - Front, Front Left or Front Right

Suspension Strut Mount for Front Applications

Westar ST-1921 is a suspension strut mount built for front-end service on select Chevrolet, Buick, Oldsmobile, and Pontiac applications. It is designed to support suspension rotation, secure the strut to the body, and reduce road noise and vibration transfer into the cabin.

• Provides a pivot point for the suspension to rotate smoothly during steering
• Helps keep suspension geometry within the correct operating range to support tire and component wear control
• Locks the strut and body together for a secure upper mounting point
• Includes a noise-dampening function to reduce vibration and road noise
• Built with materials selected for the specific application and finished to help extend service life
