Product Details
KYB Strut-Plus SR4277 is engineered as an OE-restoring front right suspension strut and coil spring assembly. KYB uses its original equipment supplier experience to match damping control and spring rate to the vehicle’s intended ride and handling characteristics. This part cross-references Monroe Shocks & Struts (e.g., 172530, 182530) for the same application. Compatible with 2008-2009 Ford Taurus, front right, and 2008-2009 Mercury Sable, front right. The SR4277 part number is a direct reference for shoppers comparing OE-style replacement options for these vehicles.
Common Issues This Assembly Can Address
- Front-end sag or reduced ride height
- Loose, unstable, or inconsistent steering feel
- Excessive bounce or poor body control over bumps
- Uneven suspension response on the front right corner
- Wear-related loss of original ride and handling balance
Installation Notes and Tips
Install according to the manufacturer’s instructions and replace the suspension strut and coil spring assembly as a complete unit. Verify front right fitment before ordering, and confirm that the vehicle is a 2008-2009 Ford Taurus or 2008-2009 Mercury Sable. Because this is a pre-assembled strut and spring unit, it is intended for professional suspension service and proper alignment after installation.
Quality Assurance
KYB designs Strut-Plus assemblies to restore OE-level ride height and handling control using application-specific components. The SR4277 is assembled in the USA and built with KYB’s OE-focused engineering approach for the front suspension.
