The Muncie SH8 Series Power Take-Off, part number SH8B-U6809-P1ZX or SH8BU6809P1ZX, is an air-shift-only PTO built for high-torque applications on medium-duty trucks. The integral air shift design keeps the air cylinder fully enclosed within the housing, eliminating the exposed cylinder found on older designs. The 8-bolt cast iron housing mounts securely to the transmission and delivers the structural strength heavy-duty hydraulic installations demand. With 17 input gear sets available across the SH8 series, this unit fits most popular transmission configurations, while 12 output shaft options accommodate a wide range of pump types. Five speed ratios provide flexibility across different drive requirements. Call us to confirm the correct ratio and output shaft configuration for your specific application.
