The Muncie SH8S-M6509-A1KX or SH8SM6509A1KX is an SH8 Series air-shift power take-off built for high-torque truck applications. The integral air shift design keeps the air cylinder fully enclosed within the housing, eliminating exposed components. The 8-bolt cast iron housing mounts securely to the transmission, and the unit accommodates 17 input gear sets to cover most popular transmission configurations. Five available speed ratios let you match output to the application, while 12 output shaft options cover the most common pump types. Intermittent torque ratings range from 325 to 400 lb-ft depending on the speed ratio selected. Call us to confirm proper fit for your specific transmission and pump setup.
