The Muncie SH8S-M6509-E1PX (also referenced as SH8SM6509E1PX) is a Muncie SH8 Series air shift power take-off built for high-torque truck applications. The integral air shift design keeps the air cylinder fully enclosed inside the housing, eliminating exposed external components. The 8-bolt cast iron housing mounts solidly and accommodates 17 input gear sets, covering most popular transmission configurations. Five available speed ratios let you match output to the driven pump, and 12 output shaft options cover most pump types. At the top speed ratio, this SH8 Series unit is rated to 400 ft-lb intermittent torque and 280 ft-lb continuous torque at 1,000 RPM. Call us to confirm the correct ratio and output shaft configuration for your specific application.
