PRESENTING THE CLASS 8 TRUCKS BUILT TO WITHSTAND WHATEVER THE DAY BRINGS.
Western Star has a long history of building Class 8 trucks that deliver more so you can do more. 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 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, over the road trucks, log trucks, boom trucks, dump trucks, mixer trucks and more. They are purpose-built trucks that can take on anything.
