KYB Suspension Shock Absorber P/N:554367
Help restore the designed ride control and handling of your 2019-2023 Mazda CX-9 with the KYB Excel-G Shock Absorber (MPN 3440142), a rear-position gas shock built as a direct-fit replacement for the 2019-2023 Mazda CX-9 (see the "Vehicles it fits" section for the full application list). This KYB shock absorber is calibrated to bring back the vehicle's original, designed performance rather than change it — which is why the Excel-G carries the OEA (Original Equipment for the Aftermarket) classification and is a preferred choice among professional technicians.
KYB is a world-leading supplier of shocks and struts to new-vehicle manufacturers, and the Excel-G includes every quality component found in KYB's global OEM products.
