Expert Reply:

You will want to make sure that the inside diameter of 4 inches is the same, but the Bulldog BX1 Gooseneck Coupler # BD1289040300 has an outside diameter of 4-1/2 inches and will fit the standard gooseneck ball size of 2-5/16 inches. It is rated for 30,000 lbs, has a retracted height of 24-1/2 inches and has a vertical range adjustment of 8 inches. This gooseneck coupler also comes with a Limited 5-Year Warranty.

The square equivalent is the Bulldog BX1 Gooseneck Coupler # BD1289140300 which has a 30,000 lbs weight capacity as well. It has an Outer Tube measurement of 4-1/2 inches and a retracted height of 31 inches. If you are just needing a replacement Inner Tube you can use the Bulldog BX1 Gooseneck Coupler Inner Tube # BD1289210300 which still has the 4 inch measurement that you will want to double check.
