Product Details

KYB Strut-Plus SR4011 is part of the Strut-Plus line, a KYB product family focused on complete suspension strut and spring assemblies that simplify replacement while maintaining OE-style ride and control characteristics. This rear assembly is built for 2000-2007 Ford Taurus, rear, and 2000-2005 Mercury Sable, rear. It is designed to restore suspension geometry, support proper ride height, and help maintain predictable handling after the original rear strut assembly has worn out.

This part cross-references Monroe Shocks & Struts (e.g., 171616) for the same application.

Common Problems This Part Can Address

• Rear-end sagging or uneven ride height
• Excessive bouncing or poor damping control
• Reduced stability during braking, cornering, or lane changes
• Clunking or worn suspension feel from a deteriorated strut assembly
• Loss of steering and chassis response caused by worn rear suspension components

Installation Notes and Tips

Install SR4011 on the rear suspension only for the listed applications. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions, and verify that the vehicle is properly supported before removal. Because this is a pre-assembled unit, it is intended to reduce the need for spring transfer during installation. Always confirm vehicle year, make, model, and rear position before ordering.
