X-SERIES

When you change an industry, there's only one way to follow it up.

Change it again.

Presenting the Class 8 commercial vehicles built to withstand whatever the day brings.

 

Western Star has a long history of building Class 8 commercial trucks that deliver more so you can do more. And we upped that commitment in 2020 with the 49X, possibly the best vocational truck ever built. Then our drive to deliver more reached a new level with the new 47X. Now, with the new 57X we’ve taken that commitment to the road.

 

Combined, the X-Series family of trucks breaks new ground in safety, durability, technology and versatility for heavy haulers, log haulers, over the road tractors, boom trucks, dump trucks, mixers and more. They are purpose-built trucks that can take on anything.
