Single reduction axle has only one speed reducer to control the speed, while double reduction axle has a major speed reducer and a side speed reducing system. But how should we select regarding the difference between the two?

Due to the structure limit, single reduction drive needs bigger basin gear, which means the ground clearance will go smaller, resulting in the low passability. Double reduction axle resolve this conflict perfectly by installing a speed reducing gear between the axle shaft and the wheel. In this way, the basin gear of main speed reducer becomes smaller and the truck passability is improved. This is why double reduction axle could deal with more complicated road condition.
