The Bonanza Trail and Four Wheel Drive- continued.

 “Low Range” is essentially another set of gears (contained within the transfer case) that slow the vehicle down while multiplying the torque (the force that causes things like axles to rotate) supplied by the engine.  This enables the vehicle to “crawl” over certain obstacles, or up steep, rocky grades.  It also enables the driver to control the vehicle’s speed more precisely, and it greatly amplifies the engine-braking effect when descending steep grades.  Why is that important?  Because it reduces the need for the driver to “ride” the brakes in order to keep the vehicle’s speed from building up.
