Product Details

The KYB Excel-G line is engineered to restore the vehicle’s original designed performance rather than change it. Built on KYB OE assembly lines with OE-quality components, the 3440014 rear shock is calibrated for the suspension demands of the Mazda CX-5 and Mazda 6. This part number 3440014 is an OEA-style aftermarket replacement that supports consistent ride control, braking stability, and lane-change response while working with the suspension geometry the vehicle was designed around.
