Benefits and Features


  • Haul your materials faster with an accelerated travel speed.
  • Put more power to the ground with increased torque.
  • Enjoy greater productivity while using a more responsive Traction
    Control System (TCS).
  • Reduce tire wear with maximum by engaging TCS early in the slip.
  • Strong, predictable performance helps operators achieve the lowest cost per ton.


  • Up to 11% less fuel consumption.
