2023 Western Star 4900 EX

Dependability never goes out of style.

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.

Stretch your legs without ever stepping outside.

While most interiors out there feature sleepers that seem little more than afterthoughts, Western Star's all-new interior is planned with comfort, space and storage to spare. With four sleeper models, five roof heights and a high-quality walkthrough design, you can outfit your truck exactly how you want. Add to that a variety of ugraded material and color options and you have the kind of workplace you've always wanted. After all, it's your truck. It should fit you, not the other way around.

Features may include:

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.
