Westar ST-3906 Suspension Strut Mount - Front Left

Westar ST-3906 Front Left Strut Mount

Westar ST-3906 is a front left suspension strut mount built for direct replacement on select Toyota and Lexus applications. It supports strut movement, secures the strut to the body, and helps isolate road noise and vibration for a more controlled ride.

Key Features

• Provides a pivot point for the suspension to rotate while maintaining correct steering geometry and helping reduce tire and component wear
• Locks the strut and body together for a secure upper mounting point
• Includes a noise-dampening design to reduce road noise and vibration transfer into the cabin
• Built with materials selected for the specific application and finished to help extend service life
• Direct-fit suspension strut mount for front left installation
