Rear Shock Assembly for Mazda CX-5

Restore rear suspension control on the 2019-2023 Mazda CX-5 with the KYB Excel-G Shock and Mount Assembly, part number SA1012. This nitrogen gas-charged, twin-tube rear shock is built to return original ride control, stability, stopping response, lane-change feel, and handling balance.

Excel-G OE Replacement Design

KYB Excel-G is the brand’s OE replacement line for drivers who want factory-style performance rather than a changed ride character. The SA1012 is built on KYB OE assembly lines and uses OE-quality components calibrated to restore the vehicle’s original suspension behavior. KYB is also a supplier of shocks and struts to new vehicle manufacturers, which is reflected in the Excel-G approach to fit and function.

Detailed Product Overview

The KYB SA1012 is engineered for the rear of the Mazda CX-5 and is a practical choice when the goal is to restore suspension response after wear. Its OE-style calibration helps bring back consistent damping, which supports predictable braking, cornering, and body control. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Can Address

• Rear-end bounce or excessive oscillation over bumps
• Reduced stability during lane changes and highway driving
• Soft, loose, or inconsistent rear suspension feel
• Uneven damping response from a worn shock absorber
• Noisy or degraded rear shock assembly performance

Installation Notes

Verify rear fitment on the 2019-2023 Mazda CX-5 before installation and compare the original shock dimensions, mount style, and stroke length to the SA1012. Because this is a shock and mount assembly, it is suited to direct rear suspension replacement where the listed mount configuration matches the vehicle.

Quality Assurance

KYB manufactures Excel-G on the same OE assembly lines used for original equipment production and calibrates it to restore designed suspension performance. The SA1012 is built with OE-quality components and follows KYB’s OE replacement standards for the rear suspension of the Mazda CX-5.
