What does OEM truck parts mean?

OEM truck parts refer to parts manufactured by suppliers according to the requirements of truck manufacturers. These parts can only be provided to truck manufacturers and their authorized 4S stores. They are not allowed to be provided to other automobile factories or markets other than 4S. ‌‌

The basic meaning of OEM is branded production cooperation, also known as "OEM". Brand producers use their own key core technologies to design and develop new products and control sales channels, but their production capacity is limited, and they even have no production lines and factories. In order to increase production, reduce the risk of new production lines and win market time, brand producers entrust other manufacturers of similar products to produce through contract orders, buy out the ordered products at a low price and affix their own brand trademarks. This form of cooperation is called OEM, the manufacturer who undertakes this processing task is called OEM manufacturer, and the truck parts they produce are called OEM products‌.
