Navistar announced that its International WorkStar vocational trucks will be available with the company’s 13L MaxxForce engine with selective catalytic reduction (SCR) emissions technology.

It is the fourth International heavy-duty model to switch to SCR since Navistar announced it would install the aftertreatment technology in its vehicles.

“With the launch of the WorkStar with our 13L SCR engine, we continue to make great progress in our engine transition strategy and customers are benefitting from our expanded product line-up,” said Bill Kozek, president North America Truck and Parts, Navistar. “We’re well positioned to continue our positive momentum and we are on schedule to complete the SCR transition in our remaining heavy-duty truck offerings by early August.”

Navistar offers its ProStar and now the WorkStar with the MaxxForce 13L with SCR while the ProStar, PayStar 5900 set-back axle and 9900i are all available with the Cummins ISX15 engine. The MaxxForce 13L will be available on additional models according to a schedule determined by volume and customer demand, Navistar said.
