Product Details

KYB Strut-Plus SR4223 is part of the KYB Strut-Plus line, a suspension solution built around OE-restoring components for vehicles that need a complete front corner assembly. For the Toyota Prius front right application, this assembly combines a KYB Excel-G strut with a precision-tuned coil spring to help return the vehicle to factory ride height and handling balance. The design supports the steering pivot function of the strut while helping maintain stability and predictable control in everyday driving.

This part cross-references Monroe Shocks & Struts (e.g., 172357, 182357) for the same application. The KYB SR4223 is a direct-fit choice for drivers and technicians looking for a Toyota Prius front right strut and coil spring assembly that matches the vehicle’s original side-specific configuration.

What It Helps Address

• Front-end sag or reduced ride height
• Loose, unstable, or uneven handling
• Worn strut performance that affects steering feel
• Noisy or tired suspension response over bumps
• Ride quality changes caused by aging spring and strut components

Installation Notes
