MAXXFORCE 9 / MAXXFORCE 10

MAXXFORCE 9 / 10

The MaxxForce® 9 and MaxxForce® 10 are built on the same proven I-6 platform as Navistar’s legendary and industry-leading DT engine. This I-6 design grew from a big idea: bring to the mid-range diesel market traditional big bore features like wet-sleeve design and in-chassis rebuild capability. These two models, which bring increased 9.3-liter displacement by longer stroke, meet the requirements of more demanding applications.


MAXXFORCE 9 / 300-330 HP 860-950 lb. Torque

With a full range of automatic and manual driveline options and thousands of potential build configurations, MaxxForce® 9 is made to serve the broadest range of on-highway applications. Navistar engineers have carried forward the proven technologies and components of a time-tested platform like premium plateau-honed cylinder design, reinforced bearing-cap ladder and rugged single-box ECM.
