Kenworth’s T409 has been developed as a flexible and aerodynamic solution for maximum-length on-highway operation.

1. T409
DEFINING TOMORROW
AUSTRALIAN MADE. WORLD’S BEST.

2. Kenworth’s T409 has been
developed as a flexible and
aerodynamic solution for
maximum-length on-highway
operation.
With its athletic stance and
sweeping aerodynamic features,
the T409 is ideal for general
freight or tanker operations.
Offering up to 580 peak
horsepower, the T409
is the perfect truck for
maximum payload single
trailer and 26m B-Double
combinations with 36” sleeper.
TANKER AND GENERAL FREIGHT
DEFINING FLEXIBILITY AND VERSATILITY
A perfect truck for maximum payloads.

3. DEFINING CONTROL WITH STYLE
Designed to deliver maximum driver confidence.

4. THE WORLD’S BEST REST STOP
Superior levels of driver comfort and safety.
The best looking truck in
Australia also provides
superior levels of comfort.
Enjoy home away from home
comfort with “walk through”
sleepers that offer unsurpassed
levels of accommodation
comfort.
The T409 can be optioned
with any of Kenworth’s range
of traditional sleeper boxes.
Configurations range from
the IT flat roof 28” sleeper, an
aerodyne 36” to the luxurious
50” Aero design, offering
cupboards with hanging space,
full head room, ample storage
and optional second bunk.
Each integrated cabin/sleeper
has diamond pleated and
studded soft trim in a range
of colours and Kenworth’s
unsurpassed appointments.

5. DEFINING APPLICATION ENGINEERING
With its aerodynamic lines and class leading cooling
performance, the Kenworth T409 offers extra peace of
mind to transport professionals by reducing the drag
on their fuel dollars.

6. The T409 also sees the introduction of the Eaton “Ultrashift Plus” automated
transmission. This two-pedal transmission delivers significant improvements
in performance, superior acceleration and low speed manoeuvrability with
its revolutionary Electronic Clutch Actuation (ECA).
All Kenworth suspensions are of
the highest quality with proven
performance and reliability.
Unique to Kenworth is the eight
air bag AIRGLIDE suspension
system. Renowned for its
excellent ride and handling it is
popular across a wide range of
applications from general
freight to fuel haul.
REAR AXLE SUSPENSIONS
To get power to the ground,
we offer a selection of proven
drivetrain components for the
T4 Series from the best
suppliers available including
transmissions from Eaton,
coupled with drive axles from
Meritor and Dana.
DRIVETRAIN
Because Australia has some
of the toughest operating
conditions in the world,
Kenworth has been careful
to test maximum loads,
temperatures and humidity
across the extremes of
our continent.
This is why the class leading
cooling package minimises
engine fan cycling even in
the harshest conditions.
COOLING

7. Kenworth trucks can be built
to a variety of wheelbases with
components mounted onto the
frame to suit your needs.
We optimise the strength and
weight distribution of each
frame by locating the various
parts so that loads are evenly
spread and fuel tank capacity
can be maximised.
CHASSIS FRAME LAYOUT
At Kenworth we design our own
fuel and oil tanks. Engineering
tank packages for a variety of
applications delivers flexibility
to operators by offering multiple
fuel and oil tank combinations.
FUEL TANKS
RIGHT HAND SIDE UNDER CAB
IN CHASSIS RAIL
DIESEL PARTICULATE FILTER (DPF)
With the choice of 3 DPF locations, Kenworth
can work with you to find the most suitable for
your application.
No actions are required by the engine or the
driver during passive regeneration to keep the
filter clean.
Cummins’ testing in Australia has shown that
the maintenance interval to remove the ash will
be 500,000 kilometres in most applications.
Speak with you local dealer for further
information.
POST MOUNT
Aluminium tanks are standard for
weight saving, or you can select
steel tanks for severe applications.
Just another example of
Kenworth’s unmatched attention
to design, function and quality.

9. DEFINING SAFETY
It’s all about looking after the most important payload of all
ABS ANTILOCK BRAKING SYSTEM
Prevents wheel lock-up when the vehicle is over braked, often reducing stopping distances. Vehicles can retain directional stability
and steerability, even under emergency braking on slippery road surfaces. ABS also reduces the danger of jackknifing in the case
of vehicle combinations.
DTC DRAG TORQUE CONTROL
Prevents the driven wheels from compression locking on a slippery surface by raising engine revs to assist with vehicle stability.
ATC AUTOMATIC TRACTION CONTROL
Prevents wheel spin under acceleration as the drive torque exceeds the drive tyres to road surface adhesion. The ATC system
communicates with the engine ECU to reduce engine power or will apply the brakes to the drive wheels depending on the low
traction event.
ESP ELECTRONIC STABILITY PROGRAM
Helps to restore vehicle stability through the use of ABS, ATC, steering direction and vehicle directional stability information.
Steering angle, yaw, suspension pressure and brake application pressure sensors monitor the intended vehicle directional control
versus actual vehicle movement. ESP intervenes by applying individual wheel brakes, or reduced engine torque when required to
enhance vehicle stability. The system is compatible with multi trailer combinations.
TRM TRAILER RESPONSE MANAGEMENT
Electronic trailer brake actuation (for EBS compatible trailers only) for improved trailer braking response to assist with
reduced stopping distances.
ACB ACTIVE CRUISE WITH BRAKES
Helps assist with accident avoidance, by using on board computers and radar to engage the engine and wheel braking
systems if other vehicles on the road enter unsafe distances from the truck.
At Kenworth, protecting
the driver, vehicle, payload,
and other road users against
unexpected hazards has
always been a paramount
consideration.
Safety is built into every
T409 through Application
Engineering, a design
approach that also delivers
optimal payloads, reliability
and productivity.
With the addition of Kenworth
Electronic Brake Safety Systems
(EBSS) the result is not only
safety and proven productivity
gains through being engineered
to application, but enhanced
accident avoidance from the
comprehensive list of EBSS
options available.
