Ford’s electronic shift-on-the-fly (ESOF) 4x4 system allows you to quickly move into and out of four-wheel-drive mode by turning a dial. This design consists of hubs that lock and disengage automatically through the transfer case. One of the main advantages of this system, which comes standard on vehicles like the Ford Ranger, is that you can shift into and out of 4x4 mode while moving.
The ESOF has three different settings.
- 2H (RWD) – This is the two-wheel mode, which powers only the rear axle. It is perfect for driving on dry pavements.
- 4H (High 4x4) – This mode transfers power to all four wheels for use in sand, mud, ice, and snow.
- 4L (Low 4x4) – This mode transfers power to all four wheels with additional gearing to multiply the torque, boosting traction on slippery surfaces. It is ideal for steep inclines, sand, mud, or when towing heavy loads.
