It features an integral air shift design with no exposed air cylinder, housed in an 8-bolt cast iron body measuring 11.63 in. x 13.38 in. x 15.63 in. Five speed ratios and 17 input gear sets cover most popular transmissions, while 12 output shaft options accommodate a wide range of pump types. Intermittent torque ratings reach up to 400 lb-ft (542 Nm) at the highest speed ratios, with continuous ratings to 280 lb-ft (379 Nm).
