The hallmark of the Kenworth T600 tractor trailer is an aerodynamic design that could save up to $ 25,000 a year in fuel, depending on past mileage, according to the Kenworth Truck Company. Owned by Paccar, Kenworth manufactures medium duty and heavy duty trucks and received the Clean Air Excellence Award in 2009 from the US Environmental Protection Agency.
Engine sizes for the Kenworth T600 tractor trailer range from 11 to 15 liters and support up to 600 horsepower. Front axle ratings range from 12,000 to 14,600 pounds. Rear axle ratings range from 23,000 to 46,000 pounds in tandems. The truck is designed for online, regional and bulk transportation, and for pickup and delivery.
The Kenworth T600 fits the Class 8 heavy duty Paccar MX with a B10 design life of one million miles. The 380-485-horsepower engine has 1,450 to 1,750 pound-feet of torque and a 12.9-liter displacement. The engine warranty is two years or 250,000 miles. The engine has a rigid CGI head and block, in-block camshaft, floating oil pan, rear gear train location, and integrated balance. High pressure fuel injection uses unit injection pumps, reaching 36,000 psi at the tip of the injector. Paccar offers on-highway truck protection plans for three to five years and up to 500,000 miles.
The Kenworth T600 features an AG130 front air suspension system that can be specified in a 12,000 or 13,200 pound configuration. The AG130 uses two airbags per side to support 75 percent of the vertical load. Standard shocks have a one-piece bush. A valve controls both grade and height. The truck features a 64-inch front spring, as well as 8-bag suspension and cab-bed suspension. The saddle paddle mount functions as a U-bolt saddle, spring clamp, lower air attachment, shock mount, height control link mount, and shock pad. The AG130 system is available on the T600.
