Restore the designed ride control and handling of your Mazda CX-9 with the KYB Excel-G Suspension Shock Absorber (MPN 3440112), a rear gas shock that drops in as a direct-fit replacement for the 2016-2018 Mazda CX-9. KYB is a world-leading supplier of shocks and struts to new-vehicle manufacturers, and the Excel-G is built on the same OE assembly lines with the same OE-quality components — calibrated to restore original, designed performance rather than change it, earning its OEA (Original Equipment for the Aftermarket) classification.
- Nitrogen gas-charged twin-tube design: includes every quality component found in KYB's global OEM products and is a preferred choice among professional technicians.
- Triple-lip fluid seal: designed to reduce the chance of oil and gas leaking out.
- Vehicle-specific damping valves: hand assembled in-house to help manage tire contact, steering response and body movement.
- Supports electronic safety systems: helps keep Electronic Safety Systems performing as designed by keeping the suspension working as the manufacturer intended.
Ride comfort matters, but restoring stability, stopping, lane-change responsiveness and handling is critical — the Excel-G is engineered for that purpose. Replacing worn rear shocks in matched pairs is recommended for balanced ride control.
