Low Range (Reduction Gear)

Low range is an extra reduction gear in a 4WD transfer case that multiplies torque for steep or difficult terrain.

What is Low Range (Reduction Gear)?

It roughly halves speed in each gear and doubles torque. It is used for crawling, steep descents and towing off-road. Shifting usually requires stopping or slowing down. Low range also gives better engine braking on steep descents, so the brakes need less work. Some systems only shift in neutral, others shift on the move at low speed. Hill descent control often works best together with low range.

How it works

A second gear set in the transfer case reduces the output speed.

Why it matters for your car

Do not drive fast in low range. Follow the engagement procedure in the manual.
