The Muncie SH8S-U6812-E3EX or SH8SU6812E3EX is an 8-bolt SH Series power take-off built specifically for high-torque, air-shift-only applications. Muncie positioned the SH Series to bridge the gap between its TG and 82 Series units, giving fleets a dedicated option where torque demands exceed lighter-duty PTOs. The integral air shift design keeps the air cylinder enclosed within the housing, eliminating the exposed cylinder found on some competing designs. With 17 input gear sets available across the series, this PTO fits the most widely used truck transmissions, and 12 output shaft options cover the majority of common hydraulic pump configurations. The 8-bolt cast iron housing simplifies mounting and holds up in demanding service environments. Call us to confirm the correct configuration for your specific transmission and pump setup.
