The Muncie SH8S-U6812-E3IX or SH8SU6812E3IX is an SH8 Series air shift power take-off built for high-torque truck applications. The integral air shift design keeps the air cylinder fully enclosed inside the housing, eliminating exposed components. The 8-bolt cast iron housing mounts securely to the transmission, and 17 available input gear sets allow fitment on most popular transmission models. Five speed ratios cover a wide range of output requirements, and 12 output shaft options accommodate most common pump types. Intermittent torque capacity reaches 400 ft-lbs at speed ratios 05 and 07, stepping down to 375 ft-lbs at ratio 09 and 325 ft-lbs at ratios 12 and 13.
