Application speci c designs for industry leading performance

Engine

The 777G is powered by the updated Cat C32 ACERT diesel engine.

• For the 777G, the engine and torque converter are producing 7% more usable torque giving the truck new performance levels and quick haul cycles.

• In addition, Part Throttle Shifting provides an automotive-quality ride.

Special Package Options
