Kenworth T680 Now Standard with JOST Fifth Wheel

The Kenworth T680 on-highway flagship is now standard with the JOST JSK37USB fifth wheel.

JOST’s simple mechanism allows infinite adjustments versus notched adjustments. Wear adjustment is easily maintained with a single adjustment screw. The ability to perform maintenance and minor rebuilds on the JOST fifth wheel – without removing it from the chassis – assures owners of Kenworth trucks the lowest possible cost of ownership with JOST now positioned as the standard offering for the Kenworth T680.

The JOST fifth wheel has a low 60-pound pull force handle, making operation easier for drivers. JOST offers a five-year warranty on all of its durable cast ductile iron topplates.
