Dual-Offset Transfer Case

Like its mechanical and electrical counterpart, the Dual-Offset Transfer Case (DOTC) is typically installed in part-time four-wheel-drive off-road vehicles such as trucks and rock-crawling automobiles as well as commercial vehicles. The DOTC is designed with a 16-bit/32-bit CAN-enabled ECU that enables selection between 2WD and 4WD as well as between high and low gear ranges through an electrical switch. The reduced propeller shaft angle achieved from the double-offset design makes it suitable to be offered as a 4x4 option on vehicles with a smaller wheelbase.

Key Features:
