The Freightliner 114SD vocational truck features a set-forward axle with a standard 31-in. position or an optional 29.5-inch bridge formula configuration, and a set-back 48-in. setting for enhanced maneuverability. Front axle ratings are available up to 23,000 pounds, and heavy rear axle configurations for single axles are available up to 38,000 pounds. Tandem rear axle ratings range up to 58,000 pounds and tridem ratings are up to 69,000 pounds.
Western Star’s Class 8 vocational truck, the 4700, is targeted at dump, mixer, crane, roll-off, sewer-vac and plow applications. It is available in a set-forward and set-back configuration and features a 110-in. from bumper to back of cab. Engine options include a Detroit Diesel DD13, Cummins ISC or Cummins ISL.
Kenworth Truck Co.’s new T660 regional hauler configuration offers shorter wheelbases, tighter chassis packaging, enhanced maneuverability and weight savings, the company says. The new T660 configuration removes the standard under-cab chassis fairing and replaces it with a cab-mounted extension of the hood fender. This allows larger diameter 24.5-in. and 28.5-in. fuel tanks to fit under the cab.
The truck maker will also offer a new line of seats exclusively for the T700. The new Kenworth GT701, GT702, and GT703 seats offer an advanced air suspension system that can automatically adjust to the driver’s weight. It also offers an adjustable shock that provides drivers with various height adjustments.
All GT700 series seats offer optional heating, while the GT703 adds the option for cooling with premium leather covering. The GT703 also comes with an upper back adjustability feature that provides improved shoulder and neck support over various recline angles.
Dana’s new Diamond Series aluminum driveshaft joins Spicer steel U-joints to a new one-piece aluminum shaft, offering a driveshaft that is as strong as conventional designs, yet weighs up to 40 percent less, the company says.
Aimed at heavy-duty commercial trucks using two-piece steel driveshafts of 7.5 feet, the one-piece design — without the center bearing and one universal joint — reduces component wear, the company says. High-strength aluminum offers corrosion resistance. The driveshafts will be available late in the fourth quarter.
Aerodynamic enhancements to Mack’s on-highway Pinnacle can increase fuel efficiency by up to 12.5 percent, the company says.
