KC2203030231 Right Countershaft Assembly is an original factory part specially used for Sinotruk HW series transmissions, undertaking power transmission and torque bearing. Forged from high-strength alloy and reinforced by heat treatment, it features high structural strength, strong torsion and bending resistance, and is not easy to deform under heavy load. Internally assembled with precisely fitted gears, bearings and spacers, it ensures uniform meshing clearance, smooth transmission, low noise and stable operation. Made strictly per OEM size and process, it fits the right mounting position perfectly and can replace damaged parts directly. With vibration resistance, anti-loosening, rust and corrosion resistance, it is highly applicable for heavy-duty working conditions.

KC2203030231 Right Countershaft Assembly integrates drive gears, shaft body, bearings and positioning accessories, manufactured strictly in accordance with OEM precision technology. The material is treated by quenching and tempering to balance hardness and toughness, featuring wear resistance and fatigue resistance, avoiding looseness and tooth breakage under long-term bumpy and heavy-load operation. With strictly controlled coaxiality and tolerance, it matches perfectly with transmission housing and related parts for easy installation. The anti-rust surface resists oil and moisture erosion for long service life. It is stable and reliable for maintenance and replacement of Howo, Sitrak and other heavy-duty truck transmissions.
