Product Details

KYB Strut-Plus SR4514 is built to restore the handling and control characteristics of the rear suspension on the Toyota Prius. KYB uses OE-restoring strut technology and a coil spring developed around vehicle attributes and corner weights to help return ride height to OE specifications. As an OE supplier, KYB applies application-specific damping and side-specific construction to match the original suspension layout.

The Strut-Plus line focuses on complete strut and spring assemblies for drivers who want a direct replacement for worn rear suspension components. This part cross-references Monroe Shocks & Struts (e.g., 172394L, 182394L) for the same application.

What It Helps Address

• Rear suspension sag or reduced ride height
• Excessive bouncing after bumps
• Loose or unstable rear-end handling
