A new cab that’s just as tough as our expectations.

Truck cabs that set the standard for toughness, durability and comfort.

Constructed from a premium-grade aluminum and enhanced with steel reinforcements, the new X-Series cab was designed to meet the demanding requirements we’re always had for our cabs. Light, safe, strong and spacious so that it can help protect and retain operators while delivering greater payload and uptime for a variety of demanding applications including dump trucks, concrete mixers, log trucks and heavy haul.
