The Muncie A20-A1006-HX1BBPX or A20A1006HX1BBPX is a 10-bolt clutch shift power takeoff designed for Allison 3000 and 4000 Series transmissions. The shift cover rotates 360 degrees for flexible installation, and the pump flange is independently rotatable to accommodate a wide range of hydraulic pump positions. Tapered roller bearings extend PTO service life, and the increased output shaft diameter adds durability under sustained loads. The clutch pack design carries a single intermittent/continuous torque rating across three available housing arrangements. The unit is also compatible with the EX Drive shaft extension for applications that require additional reach. Call us to confirm the right configuration for your truck.
