International brings back the PayStar name for 5000 Seriesmixer trucks. PayStar trucks feature a Cummins ISL engine with 330 horsepower. The engine's lightweight design and 12-inch frame provide a 7.5-percent payload increase to 10 yards for the PayStar 5500 model. The PayStar 5600 can haul 11 yards legally. For additional weight savings, the mixers use a McNeilus Revolution barrel, which weighs about 2,000 pounds less than other barrels, says International. Other features include a set-back axle for manueverability and load distribution, and an aluminum cab that resists corrosion and paint oxidation. Estimated list price: $147,000.
