The Muncie SH6S-U6809-P1EX or SH6SU6809P1EX is an SH Series air-shift power take-off built for high-torque truck applications. This PTO uses an integral air-shift design that keeps the air cylinder fully enclosed, eliminating exposed components. The 6-bolt cast iron housing mounts securely to the transmission, and the series supports 17 input gear sets to fit most popular transmissions. Five speed ratios are available across the SH Series, and 12 output shaft options accommodate most common pump types. At the 05 and 07 speed ratios, intermittent torque capacity reaches 400 ft-lb (542 Nm) at 1,000 RPM. Call us to confirm the correct ratio and output shaft configuration for your application.
