T440 Medium-Duty Truck Specs, Features & Vocational Performance
For some lighter local or regional hauls, a Class 8 truck can simply be too much for the job. But, sometimes a medium duty truck just isn’t durable enough. Built on the same platform as the T470, the Kenworth T440 is a versatile medium-duty truck that delivers heavy-duty performance for regional haul, pickup and delivery, municipal, and vocational applications.
While this model was discontinued in 2021, its modern design and aerodynamic efficiency made it a favorite among drivers for its fuel economy, durable chassis strength, and proven rugged design.

Kenworth T440 Features
Rugged Chassis & Frame
The T440 is built around a rugged chassis to withstand the demanding workload of vocational applications. Its full-strength frame rails, heavy-duty crossmembers, and three-hole gussets give this truck a strong foundation for bodies, equipment, and chassis-mounted components.
Front-End Equipment
The Kenworth T440’s front end accommodates a variety of vocational equipment options. Its stamped stainless steel grille swings clear of front-mounted equipment, while the three-piece aerodynamic bumper helps to simplify installation and service around winches and PTO-driven systems. Additional bumper configurations included:
- Three-piece aerodynamic bumper
- Steel channel bumper
- Tapered steel channel bumper
- Optional bumper-delete configuration
The T440 was also available with a factory-installed PTO, providing more flexibility for specialized vocational equipment.
Lighting
The Kenworth T440 comes equipped with standard halogen projector headlights, with optional high-intensity-discharge (HID/Xenon) lighting available. Compared to standard lighting, drivers who chose HID lighting got better forward illumination during nighttime and low-light operations.
Cab & Interior
The T440 brought several driver-focused features from Kenworth’s heavier-duty truck lineup into a medium-duty platform. Extra interior features include:
- Quiet Cab package
- Remote keyless entry
- Power windows and locks
- Built-in workstation between the seats
- Adjustable telescoping tilt steering column
- Air ride cab
- Fully trimmed seating
- Kenworth Driver Information Center
Extended Day Cab & Sleeper Options
For drivers that required more interior space, the Kenworth Extended Day Cab added 6 inches of cab length and 5 inches of cab height compared with the traditional day cab. The T440 could also be configured with an air ride cab and a 38-inch Kenworth AeroCab sleeper for widespread versatility in overnight regional operations.

- Regional haul
- Pickup and delivery
- Municipal applications
- Construction
- Vocational applications
- Specialized equipment
- Straight-truck applications
- Tractor applications
- Natural gas fleet applications
