It also uses a pair of dual-locking jaws to completely wrap the kingpin and ensure a secure vehicle-trailer connection. To make the Q25 even quieter, it comes with three grease fittings and a polyethylene lube plate for optimum lubrication. Constructed from strong carbon steel and rigorously tested for safety in accordance with SAE J2638, the Q25 5th wheel hitch is the ideal extension for your full-size pickup truck.
