The one-piece cast iron housing delivers the same torque capacity as the 442 Series (250 lb-ft) while reducing potential leak paths. Shift type is wire/cable mechanical. Output is via a 1-1/4" round keyed shaft, with intermittent torque rated at 201-300 lb-ft (301-400 Nm). Internal parts are common to the Chelsea 442 Series, simplifying service. Available from Pro Gear and Transmission.
