KYB SA1005 Suspension Shock Absorber - Rear

KYB Excel-G Rear Shock Assembly

The KYB Excel-G SA1005 is a rear shock absorber and mount assembly built to restore original ride control, stability, and handling response. It is a nitrogen gas-charged, twin-tube design made on KYB OE assembly lines with OE-quality components for a direct replacement approach.

Compatible with rear suspension applications on the 2015-2019 Hyundai Sonata, 2016-2020 Kia Optima, and 2017-2020 Kia Cadenza, this Excel-G shock and mount assembly is a practical choice for drivers looking to return the vehicle to factory-style performance.

Product Details

KYB Excel-G is engineered to restore the vehicle’s original suspension behavior rather than alter it. For the Hyundai Sonata, Kia Optima, and Kia Cadenza rear suspension, the SA1005 uses the same type of OE-quality construction found on KYB OEM production lines. That makes it a strong match for owners who want consistent ride control, predictable lane-change response, and stable braking feel from a replacement shock assembly.

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

What It Helps Address

• Rear-end bounce or excessive oscillation
• Reduced stability during braking and lane changes
• Loose or unsettled ride feel over uneven pavement
• Worn rear shock performance on higher-mileage vehicles
• Loss of factory-style handling response

Installation Notes

Fits 2015-2019 Hyundai Sonata, rear; 2016-2020 Kia Optima, rear; and 2017-2020 Kia Cadenza, rear. Verify mount style, dimensions, and suspension configuration before installation. Because this is a shock and mount assembly, it can simplify replacement compared with rebuilding a worn rear unit, but proper torque procedures and alignment checks should still be followed after service.

Quality Assurance

KYB is a major OE shock and strut supplier, and the Excel-G line is built on the same production lines used for original equipment applications. The SA1005 is calibrated to restore designed suspension performance for the listed Hyundai and Kia rear applications.
