The JOST Fifth Wheel Fitting includes the locking bar used to engage the trailer kingpin and hold it in position. This component experiences significant mechanical movement during coupling and uncoupling, which may lead to wear or compromised fitment if not periodically replaced. The JOST SK3205-06 helps maintain kingpin engagement during transit to avoid unintended uncoupling or trailer movement.
