The Muncie SH8B-U6807-A1CX (also referenced as SH8BU6807A1CX) is an SH8 Series power take-off with an integral air shift design that keeps the air cylinder fully enclosed inside the housing. The 8-bolt cast iron housing mounts securely on most popular transmission applications, with 17 input gear set options and 12 output shaft configurations to match common pump types. Five speed ratios are available across the series, with intermittent torque ratings up to 400 lb-ft and continuous ratings up to 280 lb-ft depending on the ratio selected. The SH Series fills the gap between lighter and heavier PTO lines, making it a practical choice for high-torque vocational truck applications.
