On-Highway Drives MSC2® Multispeed Fan Drives

In the low-speed mode, the MSC2 draws significantly less horsepower than an engaged on/off fan clutch. This helps when hauling on steep inclines in moderate climates by increasing the horsepower available to the drivetrain. The MSC2's transition from low- to high-speed also creates less change in available horsepower than an on/off fan clutch.
