Engineered for Upfit.
The X-Series was created with Truck Equipment Manufacturers (TEMs) in mind. We designed the truck to ease body upfit for every type of truck including dump trucks, cement mixers, cranes, and engineered it with features to make it fast and simple to access wiring and add controls. All 49X technical details can be found in the Technical Resource Guide (TRG). For access to the TRG, log onto DTNAConnect.com.
The 49X chassis was designed to make it easier than ever to mount bodies for any application. The mid-chassis packaging offered on the 49X includes features that deliver clear back-of-cab to ensure more efficient body integration. Key mid-chassis packaging features include:
8-, 13-, and 23-gallon capacities — all mounted in the most forward position for consistent fill and fender gaps.
Standard battery box mounting inside the cab and under the passenger seat to optimize open frame space. Battery boxes can also be mounted between rails or frame-mounted.
Can be mounted below battery box, inside or below frame rail, or perpendicular to the frame. Aluminum air tanks are available for additional weight savings.
25-inch diameter with capacities from 60 to 150 gallons, and can be mounted either side fore or aft. 60-, 80- and 90-gallon rectangular left-hand fuel tanks with raised mounting available for belly plow applications.
Factory-installed split hydraulic/fuel tanks available to save upfit time and maximize frame space.
Updated standard air dryer mounting location clears up frame space behind the cab.
Western Star's proprietary CHEC Tools is the interface to the 49X's programmable controllers, enabling TEMs and dealers to view and modify electrical configurations on the 49X.
