The suspension, available in both 23,000 and 26,000 lb. per axle capacities, is available for the Kenworth C500, T440, T470, T800 and W900, said Alan Fennimore, vocational marketing manager.
“The ADZ is a nice addition to the Kenworth vocational product line with improved handling for tough challenges on the road and significant weight savings, which provides an opportunity to increase payload and improve operating efficiency," he said.
The ADZ suspension is designed for typical heavy-duty applications such as construction, loggers, fire, and emergency vehicles. It can also excel in severe-duty applications where heavy vertical loads, high gross combination weights, high torque drivetrains, high center of gravity loads, and significant off-road travel are expected, Kenworth said.
The suspension is engineered for independent single suspension mounting that allows for single, tandem or tridem axle truck or tractor applications. It was designed with a simplified lightweight V-rod construction that replaces the traditional track and torque rods and includes a new integral lower control arm module for improved roll stability for high center of gravity load vehicles.
Kenworth also announced that it is now offering a Cummins ISX11.9 with rear-engine power take-off (Repto) for select vocational applications.
“The use of the Cummins ISX11.9 with Repto can help eliminate the need for a front-mounted or transmission-mounted power take-off, and simplifies charge air cooler and radiator design requirements,” said Fennimore. “This latest product option for the Kenworth T800 and W900S models is especially well-suited for vocational applications such as concrete ready mix, construction, crane and cherry picker, mining and oil well field service, refuse hauler and packer, and wrecker service.”
The Cummins ISX11.9 with Repto is capable of 466 lbs.-ft. of continuous torque and a maximum rating of 520 lbs.-ft. of torque when used for intermittent load applications, Kenworth said.
