Download Product Data Sheet
The Mechanical-Shift Transfer Case is typically installed in part-time four-wheel-drive off-road vehicles such as trucks, rock-crawling vehicles. It allows the driver to select 2WD versus 4WD as well as high versus low gear ranges by means of a mechanical lever based on road conditions to provide optimum traction and stability while driving.


  • Part-time system allows driver to select two- or four-wheel drive operation.
  • Lightweight construction reduces total vehicle weight to enhance fuel use efficiency.
  • HY-VO® Chain-driven output provides 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. Reduces maintenance needs
  • Helical gearing delivers quiet, high- & low-range operation
  • Single lever shift control simplifies selection of transfer case operating modes
