Product Description:

The RVGC Gooseneck Trailer Coupler allows you to pull your 5th wheel RV camper using a Gooseneck Hitch Ball without having to bolt on an adapter. It is a one piece product that bolts onto the existing bolt holes where the 5th wheel king pin box is mounted. Kingpin boxes give 4 inches of vertical adjustment by the trailer coupler. Most 5th wheel trailer manufacturers have adjustable whole patterns to allow you an extra 3″ of adjustment, which makes the total about 7″ of adjustment.

These RVGC kingpin boxes are available in standard and cushioned kingpin box models. The cushioned models have a cushion in the vertical tube and a horizontal cushion to help smooth your towing experience.

Product Installation:

Our kingpin boxes are fitted with premium “self-latching gooseneck trailer couplers” for the standard 2-5/16 gooseneck ball. These 5th wheel King Pin Boxes for a gooseneck hitch will replace your 5th wheel kingpin box on your 5th wheel trailer and are rated at 24,000 GVW towing capacity. Simply unbolt your existing king pin box and install the RVGC in the same bolt holes. The couplers latch when the trailer is lowered onto the ball. To uncouple, you simply pull a release cable located near the trailer jack handle. The couplers have a molded hitching guide for easy coupling. The couplers are precision cast of Chrome Vanadium Steel with a Stainless steel latching pin and a stainless steel spring. The couplers carry a V19 rating of 28,000 pounds and was tested to 42,000 pounds to gain this rating.

For an idea of where your coupler will be located using these kingpin boxes for a gooseneck hitch, you can measure your 5th wheel trailer from the center of the most forward and lower bolt hole (on the kingpin box of your trailer) measure forward 19-3/32 inch and down 26-11/16 inch to 31-3/16 inches. This will give you the location of the center and top of your gooseneck ball for your new kingpin box for a gooseneck hitch.
