Fifth Wheel to Gooseneck Adapter

Say your truck has a gooseneck hitch for towing your horse trailer, but you want to go camping with your new fifth wheel. You could outfit your truck with a new fifth-wheel hitch that attaches to your existing gooseneck hitch, but that means having to move a heavy, bulky hitch into and out of your truck bed all the time.


You could also purchase an adapter that bolts onto your trailer's existing pin box. But adding a new component to your setup can keep your pin box from working how it was designed. King pin adapters can create a stiff ride and can even strain your fifth wheel's frame by adding too much height at the connection point.


A better option is to use this gooseneck-compatible pin box to easily tow your fifth-wheel trailer with your truck's gooseneck hitch. The box replaces your trailer's existing pin box, which means it's designed to act as a part of your trailer instead of simply bolting over your king pin like an adapter does.


Built-In Shock Absorption for a Smooth Ride

Executive torsion with cable

If you've ever towed a fifth-wheel trailer before, you're no stranger to road shock. Driving over uneven terrain can result in a rigid, bumpy ride. And uncomfortable fore-and-aft chucking can occur when you're starting and stopping. When all of the motions combine, the road shock can even potentially damage your truck or trailer.


This Gen-Y Hitch torsion pin box is designed to absorb road shock at the connection point to create a safe, smooth ride. This is thanks to the internal construction of the box, which is similar to that of a torsion axle.


Pivot points are built into the Gen-Y pin box adapter. This allows for movement between the box, which attaches to your trailer, and the coupler tube, which connects to the gooseneck hitch ball in your truck bed. When your trailer bounces or jerks, the coupler tube will move accordingly.


torsion diagram

Built into the Gen-Y pin box are tubes with inner bars that are surrounded by rubber cords. As the coupler end moves, these inner bars twist inside of the tubes, attempting to follow the coupler's motion. But the rubber cords prevent the bars from twisting too far. And as each bar turns, these cords compress to absorb the rough shock. This means that any shock experienced by your truck can be absorbed before it reaches your trailer, and the shock experienced by your trailer won't get transferred to your truck.


Easy to Couple and Uncouple

auto latch and cable

The Gen-Y pin box adapter makes hooking up your trailer easy thanks to its automatic latch. When your hitch ball moves into the coupler tube, the latch instantly engages. No need to manually close the socket once the coupler is on the ball.


Disconnecting is fast and easy too. This normally requires that you crawl into your truck bed to access and release the latch. But the Gen-Y adapter box can be disconnected from outside of your truck bed. The included cable attaches to the latch on the coupler's base. Just run the cable up your trailer frame and secure it in a convenient place. When you're ready to disengage the coupler, simply pull the cable to release the ball from the socket. No need to climb into your truck bed.

I wanted to switch my 5th wheel to a gooseneck. I left a question on the etrailer website, telling them exactly what truck I had and what camper I had. I asked which hitch I would need to make the conversion. I had an answer the next day!! So I ordered the hitch and….Wow!! This thing is amazing. It is very heavy duty and a perfect fit to my camper. Definitely a two man job, but a pretty quick swap.



by:

Met my expectations, I like the gooseneck style hookup for all my trailers so when we bought the RV I saw the gen-y hitch advertised, did some research and e-trailer made sure that we got the exact fit and I can tow with peace of mind and knowing that we did not do anything to void the warranty on our brand new camper, and I don't have to deal with a chunky fifth wheel in the back of my truck.

Quality Hitch! Thanks etrailer for help on getting me the correct hitch for my 2024 Forrest river sandpiper 4002fb

See what our Experts say about this Gen-Y Hitch Gooseneck and Fifth Wheel Adapters

  • Can Gen-Y Executive Replace Curt Turning Point Pin Box on Grand Design 260RD
    That's great information - I appreciate it! The Gen-Y Executive needs at least 1,600 lbs tongue weight to be able to use the lightest option. When using a 5th wheel or gooseneck setup you want your tongue weight to be 20% of the weight of the loaded trailer so for 9,500 lbs you should have at least 1,900 lbs tongue weight. When looking at the Gen-Y formula they say to use 22% tongue weight to choose their system so that still puts you in the range of the lightest option, the Gen-Y Executive...
