About this product
Pull your gooseneck trailer with a semi-tractor or pickup mounted fifth wheel. These adapters from PopUp have a standard sized king pin with a 10" round bolster plate and an 18" tube in either 4" round or 4" or 4 1/2" square. All are available in standard straight tube or offset 9" for more room between truck and trailer. Tough enough to handle up to a 24,000 lb trailer.
