Overview

Established in 1967, the original groundbreaker

The Western Star 4900 not only delivers classic looks, it delivers legendary performance. Whether on the highway or in remote forests or mines, you can count on the 4900 day in and day out. And with our ability to deliver purpose-built trucks, a short talk with your dealer is the first step to getting the one you need. Guess customer service never goes out of style either.

Features

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.

LARGE DOOR OPENING

Makes it easier and safer to get in and out of the truck.

FORGED STEEL DOOR HINGES

Internally mounted to protect 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.

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

For fifth wheel applications, the closing cross member fasteners are recessed in the frame rail to eliminate the protrusion of a bolt head which can cause damage to trailers and the chassis. Closing cross members and frame rails are tapered with recessed bolts to give a smooth transition for trailers, and reduce the risk of chassis and trailer damage.

COPPER BRASS RADIATOR

Provides superior heat transfer and is repairable in the field. Bolted steel tanks are repairable and rubber-isolated frame mounts protect against twisting.

SEVERE SERVICE CAB OPTION

Extra gussets are welded into the cab to provide extra strength for severe service application.
