Westar ST-3911 Strut Mount Bushing

Westar ST-3911 is a suspension shock absorber / strut mount bushing built for rear and front applications on select Infiniti and Nissan vehicles. It supports suspension rotation, helps secure the strut to the body, and adds noise isolation for a quieter ride.

Key Features

• Provides a pivot point that allows the suspension to rotate within proper operating dynamics
• Helps maintain steering response and reduce tire and component wear caused by binding
• Locks the strut and body together for a secure mounting interface
• Includes a noise-dampening function to reduce road noise and vibration transfer into the cabin
• Built with application-specific materials and a protective finish for durability

Application Details
