1. High bearing capacity: Satisfy the vehicle’s two driving requirements on high carrying capacity and high-speed driving, and increase the carrying capacity by more than 30% under the same road condition;
2. Low oil consumption: Under the same cargo capacity, it will save more than 10% of average oil consumption for every 100km compared with the common rear axle, and is characterized by stronger economical efficiency; 
3. Strong grade ability: The five-star auxiliary box product, which effectively improves the grade ability, is characterized by easy climbing and small losses of engine; 
4. Long service life: The five-star auxiliary box product, which adopts the motorized technical configuration between the engine and rear axle, will effectively reduce the losses of engine power during the transmission process and decrease the power loading of engine, thus prolonging the service life of engine for more than 1 year; 
5. Good stability: The strong power output of five-star auxiliary box product is connected by reinforced driving shaft and rear axle, which makes the operation of rear axle more stable and decreases its loading and abrasive wear, thereby cutting the failure rate of rear axle.
