The Muncie SH8S-U6813-P1ZX or SH8SU6813P1ZX is an SH8 Series air shift power take-off built for high-torque truck applications. It features an integral air shift design with no exposed air cylinder, an 8-bolt cast iron housing, and 17 input gear sets to fit most popular transmission configurations. Five speed ratios give this unit flexibility across a range of drive requirements, and 12 output shaft options accommodate most common pump types. Intermittent torque ratings across the five speed ratios reach up to 400 lb-ft at the 05 and 07 ratios, stepping down to 325 lb-ft at the 12 and 13 ratios. Continuous torque peaks at 280 lb-ft. Overall dimensions are 15.63 in. long x 13.38 in. wide x 11.63 in. tall. Call us to confirm proper fit for your application.
