The All-New 49X

SIMPLY THE BEST TRUCK WE’VE EVER BUILT.

WESTERN STAR TRUCKS have always been built to deliver more. More durability, more dependability and more value. And with the all-new 49X, we’ve taken that commitment even farther. This is a truck that breaks new ground both on the jobsite and in how the job gets done.

It breaks new ground in safety, in strength, in technology, in reliability and in what it means to build the world’s toughest truck. It’s a truck born from hard work, with a heritage of performing in a world of unforgiving conditions, just like the people who own them. That’s why we believe you don’t just buy a Western Star, you earn it. So, whether you’ve owned Western Star for years or never have before, it’s time to own the next Western Star.

IT’S TIME TO BREAK NEW GROUND WITH THE ALL-NEW 49X.

BUILT WITH ONE GOAL IN MIND

We spent half a decade designing and engineering the all-new 49X to be the best vocational truck on the market. Period. To achieve that, the 49X had to meet seven benchmarks we established at the start of the project. And we put it to the test to make sure it delivered on every one of them.
