The Muncie SH8S-U6813-E1PX or SH8SU6813E1PX is an air-shift power take-off from Muncie's SH8 Series, designed to bridge the gap between lighter and heavier PTO families in high-torque truck applications. The integral air shift design keeps the air cylinder internal, eliminating exposed components on the housing. Mounting uses an 8-bolt cast iron housing that fits a wide range of transmission openings, supported by 17 input gear set options covering most popular transmissions. Five speed ratios are available, and 12 output shaft configurations accommodate the most common hydraulic pump types. Torque ratings vary by speed ratio, reaching up to 400 lb-ft intermittent and 280 lb-ft continuous at ratios 05 and 07. Call us to confirm proper fit for your application.
