KYB Strut-Plus SR4751 Front Left Assembly

The KYB Strut-Plus SR4751 is a front left suspension strut and coil spring assembly built for Toyota applications that need OE-style ride height and handling restoration. It combines a KYB OE-restoring strut with a high carbon steel coil spring to help return the vehicle to factory specifications.

Compatible with select Toyota Corolla, Prius, Prius AWD-e, and Prius Prime models, this assembly is engineered around vehicle weight, corner weights, and ride height requirements. The KYB Strut-Plus SR4751 is a direct-fit solution for drivers replacing a worn front left strut assembly on a Toyota Corolla or Prius platform.

Product Details

KYB Strut-Plus is a product line focused on restoring original suspension geometry and ride characteristics with a complete strut-and-spring assembly. For SR4751, KYB pairs its restoring strut design with a coil spring developed for the vehicle’s attributes and corner weights, helping maintain the intended front ride height and steering response. As an OE supplier, KYB applies factory-oriented engineering to this Toyota Corolla and Prius front left assembly.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Can Address

• Front-end sag from a fatigued coil spring
• Uneven ride height on the left front corner
• Excessive bounce or reduced damping from a worn strut
• Loose or inconsistent steering feel tied to suspension wear
• Loss of factory ride control on Toyota Corolla and Prius models

Installation Notes

Fits 2019-2024 Toyota Corolla, front left. Fits 2016-2022 Toyota Prius, front left. Fits 2019-2022 Toyota Prius AWD-e, front left. Fits 2017-2022 Toyota Prius Prime, front left.

Verify the vehicle’s trim and suspension configuration before installation. Because this is a complete strut and spring assembly, it is suited for replacing the front left corner as a unit rather than transferring the spring from the old strut.

Quality Assurance

KYB manufactures OE-focused suspension components and builds the Strut-Plus line to restore handling, control, and ride height using application-specific engineering. SR4751 follows that approach for Toyota Corolla and Prius front left fitments.
