57X Cab

Comfort while driving. Comfort when not.

Western Star’s focus on building  the most comfortable cabs possible continues with the 57X. Lightweight steel-reinforced aluminum cabs offer a host of features designed to reduce noise and increase comfort to keep driver’s efficient and safe.

57X Sleeper


Long days on the road are only possible when a driver has ample chance to rest and recharge. With that in mind, the 57X features a completely redesigned and upgraded drivers lounge. But most importantly, we’ve also made it customizable to address the priorities and preferences of each driver.


Features Include:

  • Pick your space – 60-inch Mid Roof, 72-inch Mid Roof or 72-inch Stratosphere High Roof
  • Optional driver’s loft features a two-seat dinette/ worktable that can be folded flat to allow a full-sized, Murphy-style bed
  • A traditional double-bunk option with an easily released telescoping ladder rated at 400 lbs.
  • Standard LED ambient lighting and dimmer switch on 72” raised roof models
  • Ample insulation, sound-deadening materials and new designs make it our quietest cab ever

  • Flat-panel TV bracket that swivels and can support up to a 26” screen
  • Larger microwave cabinet to accommodate standard appliances
  • Larger refrigerator with matching cabinetry or a customer-supplied refrigerator option
  • Wardrobe cabinet with four inches of additional hanging length
  • Multiple DC power outlets
  • A variety of powerful inverter and inverter pre-wire options for AC-powered products
