What is the Western Star 49X?
Western Star’s 49X is a vocational truck family. Its catalogue includes a Power Hood configuration as well as the main 49X specification. That suffix should be recorded when checking cooling-package and body-layout requirements; two 49X listings need not describe the same build.
What matters in a comparison
For a 49X used in demanding work, obtain the actual application specification instead of choosing from the maximum engine rating. Describe load, site conditions, body operation and working hours to the supplier. Compare the complete build with the 47X if packaging or payload is important. Keep repairs to the work body separate from chassis maintenance in the budget so both are counted.
Questions to take to the supplier
- Which 49X hood and cooling configuration is fitted?
- What duty cycle was the truck specified for?
- Which body and chassis records are available?
