The Muncie SH8S-U6809-P3EX or SH8SU6809P3EX is a heavy-duty power takeoff built around an integral air shift design that keeps the air cylinder enclosed within the housing, eliminating exposed external components. The 8-bolt cast iron housing provides a solid, high-strength mounting platform. Five speed ratios and 17 input gear sets give this unit broad transmission compatibility, while 12 output shaft options accommodate most pump types commonly found in vocational truck applications. Continuous torque ratings run from 228 lb-ft at the higher speed ratios up to 280 lb-ft at the lower ratios, with intermittent torque reaching 400 lb-ft. Call us to confirm proper fit for your transmission and pump configuration.
