The Muncie SH8 Series power take-off, part number SH8S-U6813-E3PX or SH8SU6813E3PX, is an air-shift-only PTO built for high-torque truck applications. It carries an 8-bolt cast iron housing for straightforward mounting and structural strength. The integral air shift design keeps the air cylinder enclosed, eliminating the exposed cylinder common on older designs. With 17 input gear sets, it covers most popular transmission configurations, while 5 available speed ratios and 12 output shaft options give it broad compatibility across common hydraulic pump types. Torque and horsepower ratings vary by speed ratio, with intermittent ratings reaching up to 400 lb-ft and 76 HP at 1,000 RPM. Call us to confirm the right configuration for your application.
