Gooseneck Trailer Coupler Inner Tube Only with 4 Inch Diameter

Published 04/04/2014

Question:

Hello The inner tube dimensions displayed for this product are the same for the outer tube. I only need the inner tube, with a 4inch diameter. Is that the true dimension of this product???

The 4-1/2 inch diameter is correct. The gooseneck coupler # BD0287690300 is not designed to fit inside of another tube because it is meant to be welded directly to a trailer. So it was built with the 4-1/2 inch diameter all the way down.

For a 20K inner tube only that does fit inside another tube and has a 4 inch diameter we have # BD0287610300 and # BD1289170300. We also have other capacities, each with a 4 inch diameter outer tube that I have linked for you. The only one in the list without a 4 inch outer diameter is # BD0287690300.
