The Muncie SH Series Power Take-Off, part number SH8B-U6809-A1ZX or SH8BU6809A1ZX, is an air-shift-only PTO built for high-torque applications. It fills the gap between Muncie's TG and 82 Series, with an integral air shift design that keeps all air cylinder hardware internal. The 8-bolt cast iron housing mounts securely to the transmission without an exposed cylinder. Seventeen input gear sets cover most popular transmission configurations, and 12 output shaft options suit a wide range of pump types. Five available speed ratios let you match output to the demands of the specific application. Call us to confirm the correct configuration for your truck and pump setup.
