Peterbilt has selected the JOST JSK37 12” inboard air-slide fifthwheel as standard on its Model 579 Class 8 truck. The base of the new JOST JSK37 inboard slider is 23 pounds lighter than previous models allowing for increased payloads and higher profitability for fleets.
“We are pleased that Peterbilt has made the lightweight slider JSK37 standard on their Model 579 trucks,” said George Smith, senior account manager for JOST International. “In addition to the weight savings Peterbilt customers will realize, they will also experience other benefits of JOST fifthwheels that include ease of use, infinite adjustment possibilities, and reliability.”
JOST officials said their fifthwheels are the simplest and safest design in the market with only four moving parts. The positive coupling design ensures a true connection. Upon contact, the spring-loaded steel locking bar automatically slides into position securing the kingpin. JOST offers a five-year warranty on all of its durable cast ductile iron top plates.
JOST International is a global manufacturer of fifth wheels, landing gear, and king pins.
