Truck ratings for the ISL increased from 330 horsepower to 350, and torque rose nearly 9 percent from 1,150 lbs.-ft. to 1,250 lbs.-ft. The ISC now includes roller followers, like the ISL. Cummins simplified maintenance by eliminating the water-filter requirement and doubling the fuel-filter service intervals.
