Ask a Question

This raised gooseneck ball model hitch is designed to tow a fifth wheel trailer with your standard pickup bed rails.

The lightweight "A" Frame elevates a 2-5/16" ball up to the height of a normal fifth wheel king pin. You then install the included adapter on your king pin and set the trailer on the ball like a gooseneck. The hitch pulls the trailer from the same position so you do not add any stress to the fifth wheel like gooseneck adapters.

    Option to Add Safety Chains:

    Although safety chains are not required for fifth-wheel connections, some states require safety chains for towing specifically on a ball. Some people may also feel more comfortable having this added safety measure, and they can easily be added to your truck.

    Our Safety Chains are built tough! They have been road-tested and meet all current requirements. They come with everything needed to install with your Ultimate Connection (Rail or Gooseneck version), creating a quick installation.

    NOTE: The two eyelet bolts replace the king pin coupler bolts that ship with the Ultimate 5th Wheel Connection (Rail and Gooseneck version).
