The Muncie SH8S-S6807-E1EX (also referenced as SH8SS6807E1EX) is an SH8 Series air-shift power take-off built for high-torque truck applications. It mounts via an 8-bolt cast iron housing and uses an integral air shift design with no exposed air cylinder, keeping installation clean and reducing potential failure points. The unit supports 17 input gear sets to fit most popular transmissions, and 12 output shaft options to accommodate most common pump configurations. Five speed ratios are available across the series. Intermittent torque ratings reach up to 400 lb-ft (542 Nm) at the lower speed ratios, with continuous ratings up to 280 lb-ft (379 Nm). Available from Pro Gear and Transmission.
