Cummins X15 & Endurant Powertrain

Power comes from the legendary 15.0L Cummins X15 rated at 450 horsepower. This engine was designed for fleets and owner-operators who demand dependable performance across a wide variety of freight applications. It delivers the torque needed to confidently pull heavy loads through mountain grades while remaining fuel efficient during long interstate runs.

The PACCAR Endurant 12-speed automated transmission keeps the engine operating in its optimal RPM range by making fast, intelligent gear changes. The result is improved fuel economy, smoother shifting, reduced driver fatigue, and lower operating costs compared to a traditional manual transmission.

3.08 Rear Axle Ratio

The efficient 3.08 rear axle ratio was selected to maximize highway fuel economy. By allowing the engine to turn lower RPM at cruising speed, it reduces fuel consumption, engine wear, and cab noise while still providing excellent pulling performance for today's freight demands.

AG400L Air Ride Suspension

Kenworth's AG400L air ride suspension delivers outstanding ride quality by reducing road vibration and shock. This not only minimizes driver fatigue but also helps protect valuable freight, making it one of the most popular suspension choices for premium over-the-road operations.
