The Muncie SH8S-U6813-A1BX (also referenced as SH8SU6813A1BX) is an air-shift-only power take-off from Muncie's SH Series, built for high-torque applications that fall between the TG and 82 Series in capacity. The integral air shift design eliminates the exposed air cylinder, keeping the unit compact and protected. An 8-bolt cast iron housing simplifies mounting and adds structural strength. With 17 input gear sets available across the series, this PTO accommodates most popular transmission configurations, and 12 output shaft options cover the widest range of hydraulic pump types. Five speed ratios give the installer flexibility to match pump requirements. Call us to confirm proper fit for your specific transmission and output shaft needs.
