Western Star

      The 4900EX with its extra-long nose is Western Star's principal large car, though other 4900s can be, too, if they want. The Stratosphere sleeper family for the 4900 series now includes 40- and 54-inch sizes as well as an 82-inch Ultra High model, joining existing 68- and 82-inch Stratosphere sleepers. All feature enough headroom for no-stoop standing in the cab and while walking into the sleepers.
      Other HD models: The 4900FA (with forward-set steer axle) and 4900SA (with a setback axle) complement the longer EX. The mostly off-road 6900XD, with extra-heavy-duty chassis and driveline components, is used principally in mining and oil field work.
      EPA '07 Diesels: As part of the Sterling organization (and therefore the Freightliner family), Western Star makes the Detroit Series 60 standard in its 4900FA and SA, with the MBE 4000 and Cat C13 and C15 as options. The 4900EX and 6900XD are standard with the S60 and available with the C15.
