Review of Curt Gooseneck and Fifth Wheel Adapters C16210

Speaker 1: Today, we're going to take a look at the Curt X5 5th Wheel Base Rail adapter for the Curt Double Lock gooseneck trailer hitches. This has a 20,000 pound weight capacity.This adapter is designed to mount into your Curt gooseneck trailer hitch and it supplies these above bed base rails that are necessary for installing a 5th wheel hitch in your vehicle. This part is designed to work with the Curt Double Lock Flip and Store gooseneck hitch, part number 60607, 60615, 60620, and 60625.Let me just rotate this. I'm going to show you the round. Here's your round shaft that would drop into the Curt Double Lock Flip and Store gooseneck hitch. The Double Lock design is the one that has the dual pin locking system so once this drops in, you release the handle and the dual pins will lock it into place.These rails, once they're installed, they are compatible with Curt, B and W, Demco, Draw-Tite, Hidden Hitch, Husky, Reese, and Valley above bed 5th wheel trailer hitches.

Any of those will fit into these rails.This is a very fast, easy installation. Just drop the adapter into the round gooseneck ball hole. The dual pins will lock it into place. On the very ends under each, right over here, there are rubber pads to help prevent the rails from sliding in your truck bed.This adapter is a sturdy steel construction. Has a nice black carbide powder-coat finish to help resist corrosion and it is also cold-cured in a liquid Bonderite coating for superior durability and rust resistance.This part is made in the U.S.A.The specs again.

The gross towing weight capacity on this part is 20,000 pounds, but one note you do want to be aware that capacity is limited to the lowest grading towing component.But that should do it for the review on the Curt X5 5th Wheel Base Rail Adapter for Curt Double Lock gooseneck trailer hitches and this has a 20,000 pound weight capacity.
