They analyze the performance and quality of all the parts through a variety of laboratory and real-world test as well as virtual simulations, 3D modeling and in-house Dynamometer Testing. Additionally, 100% testing and inspection is performed for every Water Pump, Oil Pump, Synchronizer, Gear, and Cylinder-Head before parts are packaged and ready for sale.
