The Muncie SH6S-S6807-M3SX (also referenced as SH6SS6807M3SX) is an SH Series power take-off built for air shift operation in high-torque truck applications. The SH Series fills the gap between the TG and 82 Series, offering an integral air shift design with no exposed air cylinder. The 6-bolt cast iron housing mounts to most popular transmissions, supported by 17 input gear set options. Five speed ratios and 12 output shaft options cover a wide range of pump types. Rated up to 76 intermittent HP at 1,000 RPM, with intermittent torque reaching 400 lb-ft depending on the speed ratio selected. Dimensions are 11.63 in. H x 13.38 in. W x 15.63 in. L. Available from Pro Gear and Transmission. Call us to confirm proper fit for your transmission and pump setup.
