Navistar International Corp. re-launched its International 9900i and PayStar 5900 SBA models at ExpoCam, Canada's National Truck Show.
The vehicles now feature the high-horsepower capabilities of the Cummins ISX15 engine with SCR.
Horsepower ratings range from 400 to 600, with 1,450 to 2050 pounds-feet of torque.
Customers can expect to see the same chiseled hood with a bevy of chrome options for the 9900i, while the heavy-duty PayStar 5900 features frame rail options and an aluminum cab.
Production of both vehicles began earlier this month and the company is now taking orders. The 9900i is available exclusively with the ISX15 engine, while the PayStar 5900 is also available with the MaxxForce 13 engine with SCR.
This announcement comes just four months after the first ProStar equipped with the Cummins ISX15 with SCR rolled off the production line.
