The Muncie SH8S-U6807-M3EX is an SH Series power take-off built for high-torque applications on medium-duty trucks. This PTO uses an integral air shift design with no exposed air cylinder, keeping the installation clean and the shift mechanism protected. The 8-bolt cast iron housing mounts securely and handles demanding duty cycles. With 17 input gear sets available across the SH Series, this unit covers most popular transmission applications, and 12 output shaft options accommodate most common pump configurations. Five speed ratios give operators the flexibility to match pump speed to the job. Intermittent torque ratings reach 400 lb.ft. at the .05 and .07 speed ratios. Call us to confirm proper fit for your specific transmission and pump combination.
