The Muncie SH8B-U6807-A3PX (also referenced as SH8BU6807A3PX) is an SH Series air-shift power take-off built for high-torque truck applications. The SH Series fills the gap between Muncie's TG and 82 Series PTOs, and this unit features an 8-bolt cast iron housing for high-strength, straightforward mounting. The integral air-shift design keeps the air cylinder fully enclosed, protecting the mechanism from road debris and contamination. Five speed ratios cover a wide range of output requirements, and 17 available input gear sets make the SH Series compatible with most popular transmissions. Twelve output shaft options accommodate most common hydraulic pump types. Call us to confirm proper fit for your application.
