Western Star 5700
Purpose-built for the bottom line.
When we decided to build a fuel efficient truck, we took that efficiency to the extreme. Every feature and component of this truck was refined to get maximum aerodynamics, efficiency and dependability. And we did it without sacrificing the kind of looks that let everyone know this aerodynamic truck is every bit a Western Star. Check out the features to get part of the story, then find your nearest dealer to get the rest.
Western Star 5700 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.
The Largest Door Openings
... in the industry. Makes 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 Fastners
Can be retorqued in the field as needed, unlike huck bolts. Grade 8 fasteners allow for equipment to be installed on the frame without having to cut off huck bolts with a torch (and damaging frame integrity).
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 Wiring
Laser etching and color coding ensures ability to troubleshoot wiring issues for the life of the truck.
Cab Insulation
Barium insulation is placed between the double walled steel cab. This increases the thermal and acoustic insulation of the truck. Our floor pads are nearly an inch 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 Rockers
Large waterproof switches are easy to operate with gloves on and are protected from water and salt which can create shorts.
Convex Gauges
Prevents glare and improves readability of gauges for added safety and less driver fatigue.
Suspended Pedals
Suspended brake and clutch pedals prevents objects from becoming lodged behind pedals.
Power Dist. 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 while working on fuses rather than accessing them in a cumbersome location.
Wiring Raceway
We put our body builder interface connector and transmission control unit in the cab and out of the elements. You'll find a bolt-in pass-through plate in the cab floor to eliminate unnecessary drilling, and a dedicated floor channel with an easy-to-remove top that provides plenty of room for you to run your own wiring.
Hinged Dash
Provides quick access to wiring for service.
Nodal Engine Warning
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.
