KIRKLAND, Wash. — Kenworth Truck Company now offers selected Jost International fifth wheels as published options on new Kenworth trucks.
Jost fifth wheels have been previously available in the aftermarket through participating Kenworth dealers in the U.S. and Canada. Jost also has been the standard fifth wheel for years on trucks manufactured by DAF, PACCAR’s European truck manufacturer.
“One key reason that fleets and owner/operators are specifying the Jost fifth wheel is the safety and reliability of the locking mechanism,” said Rich Carroll, Jost International vice president of sales and marketing. “The coupling design has some unique features that help indicate to the operator the Jost wheel is properly coupled. With only four moving parts, the Jost fifth wheel offers a positive locking mechanism, ease of operation and requires less maintenance.”
The wheel’s cast ductile iron top plate features a cushion ring. The ring is designed to protect the wheel’s throat during coupling and reduces friction between the top plate and trailer king pin, according to Carroll. In addition, the wheel can be rebuilt in less than 30 minutes without having to remove the wheel from the truck. This results in significant maintenance savings over the vehicle’s life as compared to older competitive designs. Jost fifth wheels also feature an easier-to-pull release bar.
Kenworth also offers a low-lube Jost model that is designed for mated tractor-trailer combinations, such as beverage and tanker applications.
