International WorkStar now available with Cummins ISB 6.7L engine

International Truck’s WorkStar vocational truck is now available with a Cummins ISB 6.7L engine. It is the second International vocational model to offer the engine as an option, joining the DuraStar, which has been available with the powerplant since December 2013.

“Adding the market-accepted Cummins ISB 6.7 (seen below at right) to our vocational line-up is a key part of our strategy to offer our customers the most comprehensive options of proven components in the industry,” said Bill Kozek, Navistar president, Truck and Parts. “The addition of the Cummins ISB6.7 to our WorkStar model provides customers with a winning combination of uptime, performance, productivity and durability.”

The WorkStar boasts multiple-frame rail options, a double-sided galvanized steel cab protected by an extensive five-step corrosion protection, and comes standard with the Diamond Logic electrical system.

It also features a hood and radiator package with available integral front frame extension and front engine power take-off (FEPTO) without requiring modifications to the radiator or horsepower restrictions. A roomy cab and both standard and high-visibility sloped-hood configurations for enhanced driver comfort and ease of operation are available.

The WorkStar is also available with Navistar’s proprietary 9.3L and 13L engines and a suite of traditional manual and automated-manual transmission offerings from Eaton and fully-automatic offerings from Allison.

The ISB, which is rated up to 325 hp. and 750 lbs.-ft. of torque, with higher ratings available for fire and emergency applications, features flexible horsepower and torque ratings for medium-duty applications.
