International Truck and Engine Corp is offering the new Cummins ISM 410-horsepower rating on International 8600 and 9000i Series vehicles. The ISM 425V-hp vocational rating is provided in the 5000i series vehicles. These engine ratings offer increased horsepower and 1,550 ft-lb of torque combined with a lightweight package of 2,190 pounds (dry weight).

The Cummins ISM is also equipped with Load-Based Speed Control, which manages available engine rpm based on changing operating conditions such as vehicle weight and terrain to optimize shifting. Another standard feature, Gear-Down Protection, encourages the driver to operate in top gear.
