Kenworth improves T600 specs

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.

Aluminum driveshaft

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.
