Excel-G Product Line

The KYB Excel-G line is calibrated to restore the vehicle’s original suspension behavior rather than change it. Built on KYB OE assembly lines with OE-quality components, this line is commonly selected for commercial-duty service where consistent damping and predictable control matter. Part number 343484 follows that OE-style approach for rear suspension service on the Mercedes-Benz Sprinter 2500.
