Westar ST-7985 Suspension Shock Absorber Mount - Rear
Rear Suspension Shock Mount for BMW
Westar ST-7985 is a rear suspension shock absorber mount built for select BMW applications from 2007-2015. It is designed to support proper strut movement, reduce road noise, and keep the strut and body secured together.
Key Features
- Provides a pivot point for suspension rotation to help maintain correct suspension dynamics
- Helps support steering response and reduce uneven tire and component wear
- Locks the strut and body together for secure rear suspension mounting
- Includes a noise-dampening design to reduce road vibration transfer into the cabin
- Made with application-specific materials and a protective finish for added durability
Product Details
This Westar suspension shock absorber mount is engineered for rear installation on BMW models that require a direct-fit mount for the shock/strut assembly. The ST-7985 is a practical replacement for worn or damaged rear strut mounts on vehicles such as the BMW X1, BMW 328i, and BMW 335i. This part cross-references Monroe Shocks & Struts (e.g., 907985) for the same application.
