| • | A two speed rear axle shift switch |
| • | A two speed rear axle shift control valve |
A two speed rear axle shift motor mounted on the rear carrier engages a shift fork. The shift fork selects the range chosen by the driver.
The two speed rear axle shift motor is powered by one of the following ways:
| • | Electric |
| • | Air operated |
The shift fork will perform one of the following functions:

Two possible gear ratios may come from the same gear axle.
