6900 FEATURES AT A GLANCE

THREADED SPRING PINS

Greaseable threads prevent spring from moving side to side within the shackle. Our exclusive design threads the pins directly into the spring bushing providing much more stability, improved feel and overall handling.

THE LARGEST DOOR OPENINGS

…that make it easier and safer to get in and out of the truck.

FORGED STEEL DOOR HINGES

Internally mounted protection from the elements. Greater durability to prevent sagging — a common problem with piano hinges.

DOUBLE DOOR SEALS

Both the door and the cab have a weather seal that covers its perimeter. This double seal helps maximize the efficiency of our HVAC systems and provides a quieter ride.

GRADE 8 FRAME FASTENERS

Grade 8 fasteners allow for optional equipment to be installed on the frame, and retorqued in the field as needed.

WIRING STAND OFFS

Our wiring and air bundles are supported off the frame rail. This allows debris to pass behind the bundle, eliminating the possibility of abrasion which can lead to electrical and air failures.

LASER-ETCHED CHASSIS WIRING

Laser etching and color coding ensures ability to troubleshoot wiring issues for the life of the truck.

CAB INSULATION AND SOUNDPROOFING

Barium insulation is placed between the double walled steel cab. This increases the thermal and acoustic insulation of the truck. Our floor pads are thick which further improves the quiet ride of a Western Star.

IN-CAB BLOWER MOTOR

Protected in the cab rather than being on the firewall and exposed to elements.

MARINE-GRADE ROCKER SWITCHES

Large waterproof switches are easy to operate with gloves on and are protected from water and salt which can create shorts.

SUSPENDED PEDALS

Suspended brake, clutch and accelerator pedals are easy to clean, and prevent objects from becoming lodged behind pedals — a great safety feature.

POWER DISTRIBUTION MODULES

The PDM and fuses are easily accessed by removing a panel on the passenger side dash. This allows you to sit comfortably in the cab when working on fuses rather than accessing them in an exterior location.

TOW PIN

Integral to the front closing cross member, our towing pins withstand 65k lbs of line pull from a 45 degree angle. The centralized pin equalizes pulling force between the frame rails.

OUTBOARD CAB MOUNTS

Placed as wide as possible to maximize lateral stability. Provides a more comfortable ride on rough terrain and reduces body roll in turns.

HINGED DASH

Provides quick access to wiring for service.

REPLACEABLE GRILLE BARS

Bars can be replaced one a time rather than having to replace a complete grille.

NODAL ENGINE MOUNTING
Our power units are mounted on clutch housing instead of fly wheel housing which supports the power unit closer to the output shaft of the transmission where the torque is greater. This results in less frame flex and a better ride.

J-BRACKETS AND RIBBED STRAPS

Western Star fuel tanks ride on j-brackets and are held onto the bracket with steel straps that have ribbed isolators which increases the grip on the tank to prevent tank roll.

HONEYCOMB SLEEPER WALL

A polypropylene honeycomb material is sandwiched between two sheets of aluminum. This construction results in the strongest and lightest sleeper material in the industry. Airplane bulkheads use this same strong, lightweight construction.

RECESSED BOLT HEADS

A polypropylene honeycomb material is sandwiched between two sheets of aluminum. This construction results in the strongest and lightest sleeper material in the industry. Airplane bulkheads use this same strong, lightweight construction.
