Product Details

KYB Strut-Plus SR4246 is engineered as a suspension strut and coil spring assembly that addresses the front corner of the vehicle as a complete unit. KYB, an original equipment supplier, builds this assembly around an OE-restoring strut and high-carbon steel coil spring selected to help return ride height within OE specifications. For drivers searching for a Toyota Prius front left strut assembly or a Prius Plug-In front left strut and spring replacement, this part provides a direct-fit service solution.

This part cross-references Monroe Shocks & Struts (e.g., 172689, 182689) for the same application.

What It Helps Address

• Front-end sag or uneven ride height
• Excessive bounce or reduced damping control
• Loose or imprecise steering feel from worn strut components
• Noise or harshness from a fatigued strut and spring assembly
• Restoration of OE ride and handling balance after suspension wear

Installation Notes

Fits 2010-2015 Toyota Prius, front left. Fits 2012-2015 Toyota Prius Plug-In, front left. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify side-specific fitment before installation, since this assembly is engineered for the front left position only.

Quality Assurance

KYB designs this Strut-Plus assembly using OE-based engineering and application-specific damping control to support consistent suspension performance. The part is assembled in the USA and built with components selected to match the vehicle’s original ride-height and handling requirements.
