Western Star range starting points

47X and 48X

47X is a versatile shorter-bonnet platform; 48X uses a set-forward front axle layout developed for Australian applications.

49X

49X is the high-output and high-GCM starting point with multiple cab and sleeper pathways, subject to application approval.

Series names group many wheelbases, axle layouts, engines, transmissions and cab configurations. Compare the exact Australian variant and completed vehicle.

What to check before requesting a quote

Fit the operating job

Confirm GCM approval, axle and sleeper layout, Detroit or available driveline specification, cooling, tare, trailer combination and Penske support.

Price the finished truck

Compare equivalent bodies, accessories, registration class, payload, warranty, service plan and delivery timing—not incomplete cab-chassis prices.

Map support and downtime

Confirm which branch can perform warranty work, workshop hours, mobile support, parts lead times and the contingency after a breakdown.
