The Electric-Shift-on-the-fly (ESOF) is typically installed in part-time four-wheel-drive off-road vehicles such as pickup trucks and rock-crawling automobiles. However, with a 16-bit/ 32-bit CAN -enabled Electronic Control Unit (ECU) that provides mechanism to select between 2WD and 4WD as well as between high and low gear ranges with an electrical switch, the ESOF provides a much more enhanced traction and stability over the Mechanical Shift Transfer Case. The ESOF is available in several variants.
Key Features
Part-time system allows driver to select two or four-wheel drive operation

HY-VO® Chain-driven output provides a quiet, four-wheel drive operation
Upper disconnect to chain stops unnecessary parasitic losses in two-wheel drive
Positive displacement oil pump and filter assures full lubrication when driving or towing while reducing maintenance needs
Helical gearing delivers a quiet, high & low range operation
Electric shift control simplifies selection of transfer case operating modes
Electromagnetic shift-on-the-fly provides smooth engagement of four-wheel drive at highway speeds
