What does JOST do?

JOST designs, manufactures, and supplies safety-critical systems for trucks and trailers. Their products include fifth wheel couplings, landing gears, ball bearing turntables, king pins, container locks, and truck and trailer axles.

Where are JOST products manufactured?

JOST operates two manufacturing plants and distribution centers in the United States, where they design and produce fifth wheels, landing gear, kingpins, and turntables for the road transportation market. JOST landing gear and kingpin product lines are made in the company’s Grand Haven, Michigan facility, while the fifth wheel product line is manufactured in its Greeneville, Tennessee headquarters.

How do you identify a JOST fifth wheel?

Identifying a JOST fifth wheel typically involves examining key features distinctive to JOST products. First, look for the JOST fifth wheel’s unique red identification tab, which includes the item's model and assembly numbers. You may also check for the JOST logo or branding, often prominently displayed on the fifth wheel's casting or housing. Lastly, it’s important to note that JOST fifth wheels have unique design elements, like patented locking mechanisms and grease-free technology.

What are the most commonly replaced parts of a fifth wheel?

The most commonly replaced JOST fifth wheel parts include the kingpin and the wear plate. The kingpin, which connects the tractor and trailer, experiences wear over time due to the constant coupling and decoupling of vehicles. It can become corroded or damaged, leading to decreased performance and safety concerns. The wear plate, positioned on the fifth wheel's top surface, also undergoes regular wear and tear, as it endures the weight and friction of the trailer.
