Towing should feel steady, not jarring. Inside this adapter are interior polyurethane cushions that absorb shock and vibration between the trailer and the truck. That cushioning helps smooth out rough roads, reducing bounce and minimizing wear on your trailer and tow vehicle. The result is a quieter, steadier pull that doesn’t feel harsh mile after mile.
If you already have a gooseneck hitch, this adapter makes it easy to tow your fifth wheel trailer without swapping hardware. It bolts directly over your trailer’s king pin and connects to a 2-5/16" gooseneck ball. With an adjustable height from 12" to 16", it fits multiple setups and levels your trailer for proper towing alignment.
This adapter has the muscle for serious towing. With a 20,000-lb gross towing capacity and 4,000-lb pin weight rating, it’s built for heavy fifth wheels and stays solid under load. The cast steel construction and rust-resistant powder coat finish add durability that holds up through long hauls and rough conditions.
Hitching up is straightforward thanks to the built-in positive-lock feature. A steel extension handle lets you slide the latch to lock or unlock from outside the bed—no climbing in required. Once engaged, the latch keeps the coupler secure, and you can swap the handle for a padlock (sold separately) for extra protection when parked or towing.
The adapter’s heavy-duty construction stands up to years of use. It comes with safety chains rated for 15,200 lbs each and carries a 2-year limited warranty. With its simple bolt-over installation and rust-resistant finish, it’s designed for dependable performance every time you hook up and head out.

I am still using the goose neck adapter, I now take it off if my camper is parked for a while just to reduce stress on the front end of the 5th wheel. I would recommend!

I did as I said I would do and I drilled four hole in the pin box and installed four bolts. I feel much more confident in the system. I am very happy with it at this time. To drill the holes I removed the pin box and used the adapter for a pattern, I then drilled the holes by hand. 1/2 in Drill

Raymond L.: My Ram is a 3500 4X4 SRW It has the 8Ft bed. I pulled the same Toy Hauler with two different Quad Cab PUs over the years with 6-12 ft. beds. One 2WD and one 4X4 before this one. I ordered this P/U as a Std. Cab. It is set up like a Laramie inside. towing I get 10-13 MPG. Empty 22 MPG It tows at any speed I want in the Mountains.

Great product but the bolt crushing problem is a major one that I am working directly with Convert-a-ball to get fixed. They admit it is on their end and we are working on

When I first received it I thought it would work out. But after using it for a couple of months, I had to remove it. The ride quality was terrible and the jerky ride while towing was unbearable. Plus the additional stress it put on the frame of my fifth wheel trailer over time would cause even more problems. So I removed it and installed a Curt fifth wheel hitch and now the ride is much better and smoother with no jerkiness. Would not recommend this adapter at all.

what is distance from rear bumper and lower front of fifth wheel. also it looks like you ,are at a skew with your adapter, is that with all the weight lowered on to the truck. if not how well does it tow like that.

The space between is about 2-1/2 feet. Plenty of room. That is how my hitch sets fully, its mostly due to me running 315s on my tires. But Ive pulled it all around the south and even up to the Great Lakes. Never once had a problem

Thanks for the great feedback Tyrone. Easy and no hassle hookup is a win! Adding the 3/8" bit is helpful insight for others getting ready for the install. Appreciate you choosing etrailer!
