Detailed Description

Westar ST-3913 is a suspension strut mount designed for rear installation on select Audi models. By supporting the strut assembly and allowing controlled rotation, it helps maintain suspension geometry for stable steering response and reduced tire and component wear. This part number, ST-3913, is a direct-fit style replacement for applications that require a rear strut mount with noise isolation and secure body-to-strut attachment. It cross-references Monroe Shocks & Struts 903913 for the same application.

Westar focuses on using application-specific materials and a protective finish to support durability in everyday driving conditions. For Audi 100, Audi 100 Quattro, Audi 200, Audi 200 Quattro, and Audi S6 rear suspension service, ST-3913 provides the mounting and isolation functions expected from a replacement strut mount.

What It Helps Address

• Clunking or knocking from a worn strut mount.
• Excess road noise and vibration entering the cabin.
• Loose or inconsistent strut-to-body attachment.
• Suspension movement that can affect steering feel and tire wear.
