The ISX 385 ST engine delivers 1,450/1,550 lb.-ft. of torque, and is designed with the SmartTorque feature, which automatically delivers an additional 100 lb.-ft. of torque in the top two gears of the transmission. It is designed for truck fleets looking for a higher-displacement engine in applications that do not require an engine brake.
