A specific configuration involving a rugged transfer case, this setup positions the unit separately from the transmission. This separation is achieved via a connecting driveshaft. For example, in certain off-road vehicles, this arrangement allows for greater flexibility in drivetrain design and component placement.
This design offers several advantages, including increased ground clearance due to more adaptable positioning and reduced stress on the transmission. Historically, it has been favored in applications demanding extreme durability and adaptability, particularly in custom vehicle builds or those subject to rigorous off-road conditions.
