Product Description



Heavy Duty Truck Gearbox Drivetrain Parts FAST 12JSD240 Gearbox Transmission Assembly 



The FAST 12JSD240 Gearbox Transmission Assembly is a core component of the heavy-duty truck drivetrain system, responsible for transferring engine power from the clutch assembly to the rear axle. By changing different gear ratios, the gearbox controls torque output and vehicle speed, allowing trucks to operate efficiently under various road conditions and cargo loads. Designed for high-torque commercial vehicles, the 12JSD240 transmission adopts a 12-speed manual gearbox structure with twin countershafts, providing reliable power transmission for heavy-duty transportation applications. The gearbox works together with the clutch system, drive shaft, differential assembly and rear axle to complete the vehicle power transmission process. The 12JSD240 series is commonly used in heavy trucks such as SHACMAN and compatible HOWO platforms, especially vehicles used in logistics transportation, construction, mining and engineering operations.
