The Muncie SH8S-M6512-A3EX or SH8SM6512A3EX is an air-shift-only power take-off from the SH8 Series, built for high-torque truck and vocational applications. Designed to fill the gap between the TG and 82 Series, it features an integral air shift design with no exposed air cylinder, an 8-bolt cast iron housing for strength and straightforward mounting, and compatibility with 17 input gear sets to fit most popular transmissions. Five speed ratios cover a wide range of drive requirements, and 12 output shaft options accommodate most common hydraulic pump configurations. At speed ratio 05 or 07, intermittent torque capacity reaches 400 lb-ft (542 Nm) at 1000 RPM. Call us to confirm proper fit for your transmission and pump setup.
