My pickup engine went down being unable to pull a my gooseneck with a ball application I ordered your 4 in kinpin adapter for a gooseneck trailer as you can see in the pictures it pinned in perfectly with no trouble at all with your adapter im able to get my trailers moves while repairs are made and with it i'll just have to use the fifth wheel hitch for the pickup witch is much more easy to use than a goose ball 313920

Quality manufacturing. I have a 1989 gooseneck car hauler with a 4 1/2 inch OD square tube and I'm changing it over to a king pin. This is a 4 inch OD and it fits perfectly inside my existing tubing. The holes aren't the same size as my original 4 1/2 inch but that's an easy fix. I can't wait to be able to tow my 5th wheel and my car hauler without having to switch from king pin to gooseneck ?????? 299577

  • Recommended Square Tube Gooseneck to 5th Wheel King Pin Adapter
  • It sounds like you have a gooseneck like the Atwood Gooseneck Trailer Coupler AT75401. For an adapter to kingpin, I recommend the Bulldog Gooseneck-to-5th-Wheel Trailer Coupler Adapter - Inner Tube - Square - 30,000 lbs # BD0289650300 or the # KPG5-Q25-IP.

  • Fifth Wheel Adapter Options Other Than King Pin to Gooseneck Ball
  • The Wallace Forge 5th Wheel to Gooseneck Adapter # 2085295 is a great option for using a gooseneck trailer with a 5th wheel hitch.

  • Can a Gooseneck to 5th Wheel Trailer Coupler Adapter Be Used with Bolts Instead of Locking Pins
  • As long as the inner diameter of the outer tube on your gooseneck trailer has a 4" wide opening then the Gooseneck to 5th Wheel Trailer Coupler Adapter part # KPG5-Q25-IP will still work for you. We do not have anything specifically designed for your trailer but the adapters are very universal with just slight modifications. On the adapter there are four 7/8" diameter pre drilled holes for vertical adjustment. The adjustment holes can be secured by either a locking pin or bolt. If the...
