The coupler tube for the Ultimate 5th Wheel Gooseneck Connection is the part that connects the Ultimate Connection with the gooseneck ball in the bed of the truck.

On some occasions, the standard coupler tube included with the Ultimate Connection is too short to connect to the gooseneck ball.

If you need to change the height of your gooseneck ball or the coupler tube length isn’t enough for a proper connection, you may need a replacement coupler tube to extend the connection of the Ultimate Connection so it can attach to the gooseneck ball. Refer to the Coupler Tube Chart to find the right size Coupler Tube.
