Features may include:

  • Heaviest Duty Muffler Guard
  • Heaviest duty exterior muffler protector shields expensive components. Reduces repairs, maintenance, and downtime.
  • Mirrors
  • Well positioned, large mirrors for best rear visibility. Motorized and heated mirrors are available.
  • Ideal Cab Height
  • The tallest, widest cab and door combination in the industry ensures no more ducking and twisting.
  • Best Cab Insulation
  • Premium cab insulation and matting. Superior noise and temperature insulation. Greater operator comfort. Lots of room for maintenance and also easy access from side door for under dash diagnostics/maintenance.
  • Heaviest Duty Bumper
  • Heaviest duty bumper protects driver, cab, and rest of chassis in the event of a collision. Reduces repair and maintenance costs.
