Product Details

KYB SR4457 is part of the Strut-Plus line, a product family focused on complete suspension strut and coil spring assemblies that restore factory ride height and handling balance. For the Mazda 3, this front right assembly combines a KYB strut with a vehicle-specific coil spring to match OE specifications more closely than a universal replacement. KYB’s OE supplier background is reflected in the application-specific damping and side-specific construction used in this assembly.

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

What It Helps Address

• Front-end sag or reduced ride height on the passenger side
• Loose, unstable, or inconsistent steering feel
• Excessive bounce or poor damping control
• Uneven suspension response after strut wear
• Restoration needs after replacing a worn front right strut assembly

Installation Notes

Fits 2010-2013 Mazda 3, front right. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify side, position, and vehicle year before installation to confirm correct SR4457 application for your Mazda 3.

Quality Assurance

KYB designs the Strut-Plus line to restore handling and control with OE-focused engineering, precision damping, and application-specific spring selection. The SR4457 is assembled in the USA and built as a direct-fit suspension service part for the listed application.
