We supply OEM-brand fuel-system and engine components for Freightliner trucks and Detroit Diesel engines such as the DD13 and DD15 - fuel injectors, high-pressure pumps, turbochargers and actuators, EGR components, and sensors. We carry genuine parts from brands like Bosch and BorgWarner, many with fast US shipping. Heavy-duty parts are application-specific, so verify fitment against your engine model and OEM cross-reference before ordering.
