Use your gooseneck hitch to tow your 5th-wheel trailer by hooking up with this adjustable coupler adapter. Poly cushions absorb shock for a smooth ride. Adjustable height fits multiple applications. 20,000-lb GTW.
Features:
Specs:
Notes:
After backing the vehicle under the trailer, measure from the top of the ball in the truck bed to the base of the pin box on the trailer. This will indicate the height of the adapter that you need.
The included collar slides over your fifth-wheel trailer's king pin and is held in place with set screws. Additional, larger set screws that are mounted at the top of the coupler adapter then tighten onto the collar.
This trailer coupler adapter features a simple, secure latching mechanism for safe, easy hookup with the hitch ball. The convenient extension handle grabs the sliding latch so that you can easily lock or unlock the coupler from outside the truck bed. Once the coupler is engaged, hook the handle through the hole in the sliding latch's track to ensure that it remains securely coupled. For extra safety, once the coupler is latched, you can replace the handle with a padlock (sold separately) to secure the trailer to the hitch ball during towing. Use a lock while your trailer is being stored to guard against towaway theft.
Pin Box Length
Note: There are no recommended limits to the length of pin box on which the Convert-A-Ball trailer coupler can be used.

This worked out great for my needs and made it possible to move the camper I needed to move without buying some complicated hitch assembly. My only complaint was that it was a little too tall causing the camper to ride more on the rear tires, but it was manageable . Maybe this was result of my tow vehicle .. but there was not enough adjustment to lower it down. Still it worked good.
I added the 4 bolts around the top to make the installation even stronger. As I did not trust it with only the lock bolts to the pin. Overall A+ Got the job done.
The Product installed with no problem. I just got back from a 900 mi. round trip to Utah. I was in elevations from 1000 ft above sea level to 9000 ft. above sea level. I It hooks up very easy and is very good compared the my old system. I would have given it a Excellent except that it (rotated) turned about 1/4 of an inch.on the king pin as you can see on the Photos. I will be drilling holes in the King Pin Extension and putting in the four bolts before I take it out again. I was suprised that I did not receive the optional bolts nor was I asked if I wanted them. .I did order on line so I accept responsibility for it. At no time did I feel any safty issues.
I had replaced the suspension on my trailer with the easy ride system and combined with your Convert-A-Ball Cushioned System my wife said there was a huge emprovement and I also felt a big difference it the Truck. It is a well engineered product and my raiting will go to Excellent after I put in the four Bolts. You can send me the bolts or I will get my own.
Attached are some photos of my Truck and Trailer.
The Trailer is a 2000 Forrest River Sierra Sport Toy Hauler.
I bought it new.

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.
Pulled my 34ft 5th wheel from Texas to Montana. This gooseneck adapter handled the job with no issues. It’s great not having to remove a 5th wheel hitch every time I need to haul something in my pickup bed.
Owned a year. This is our findings. Easy to install. Easy to use. Works great with our f450 gooseneck and fifth wheel trailer!
This product was very easy to install and worked flawlessly I would defiantly recommend it for use in converting your fifth wheel to a gooseneck hitch
The product is fine , but I paid $279.49 in shipping to receive it on May 30 I didn’t receive it until May 31. I would like to see Etrailer make this right

Great
The Convert-A-Ball was installed on my new 34 foot 5th wheel trailer today. I drove the trailer home from C & R trailers which is 30 miles. The drive was smooth and no trailer clunking noise. I have a son that has your Convert-A-Ball product on his trailer and they love it. I am sure I will too.
I am so happy i made this change ! No more fifth wheel in the box ! I did buy a 1 inch taller ball for this year. Works awesome !
I purchased this adapter before the note of not to be used with air ride 5th wheel hitches was added so now I am stuck with a 50lb paper weight. Don’t be me…listen to the notes that are now attached or you will spend a half hour every fuel stop retightening the adapter so you don’t lose your rv enroute.
I recently bought a 36ft 5th wheel toy hauler and needed a way to pull it, we didn't really want to install a 5th wheel hitch because we didn't want the extra holes in the bed of the truck so we bought this. I was nervous at first but this hitch adapter work very well. It mounted to the 5th wheel easily and sat right on the gooseneck ball that came built into our truck. It also disconnected from the truck with ease. We have left it hooked onto the camper for now for quick movement if needed.

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!
Easy to install I set the hitch on my jd gator and used the trailer jacks to let down on the hitch. I also bolted the hitch on (just for peace of mind).After install I did a test run of sixty miles. Worked great there was no jerking or push pull motion at all, as some reviews have said.A few months lator we went on a 500 mile trip with no problems.My truck is a 3500 dodge dually diesel.Now I can pull my farm trailers and camper on the same hitch, no moving 5th wheel in and out of truck!My camper weights 13,000 lbs.
I just wanted to tell the folks at etrailer how great of an experance I had ordering from them. I ordered a 5th wheel to gooseneck adapter. From the time the phone rang until Wayne had taken my order was less than 2 minutes. These people know their stuff and the price was great. The install was flawless, fit perfect. I was kept informed several times by e mail what the status of my order was. My order came a day early even during a holiday week.
I am sure glad to have some room in my p/u bed while pulling my 5th wheel.
Thanks Wayne and thanks etrailer

Danny I notice you have a morryde pin box on your trailer. did you change the skid plate over to the morryde RPB77006 gooseneck adapter plate. to use this adapter?
Installation is a breeze. I'm a short but stocky guy so installing it by myself wasn't hard at all. I just lowered the trailer to where I had enough leverage to hold the adapter up and be able to tighten the bolts down with the other hand. Torqued everything down to spec and was on the road in no time. Pulled off after 50 miles and retorqued everything as any good transporter does. This is where my review gets bad. The bolts that hold the adapter to the kingpin couple failed. They crushed on the ends and damaged the threads. Keep in mind, I followed the torque specs TWICE. I didn't have the twisting issues that others have had. It took me 30 min with a pull bar and a piece of pipe to get the bolts backed off enough to get the adapter off the kingpin coupler. Today I spent 30 min working ONE bolt completely out of the adapter and this is what I found. I am in contact with etrailer to get it resolved. The bolts and the inner threads are damaged. Hopefully this is just a lemon and I will get a replacement hassle free. Other than this, this is a great design and towed well.

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
I want to thank Etrailer for the great customer service I received. Emily H, was very helpful in the process of my purchase. The c5g _1216 converter ball adapter was a very well made and sturdy product. And will handle the 39ft toyhauler that I have it installed on. The installation was very easy and simple. So thanks again Etrailer for a great product and fast delivery, and great customer service.

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.
It was a day later than expected but the product is exactly what I ordered ,a quality product, thanks e-railer!

Works great, no need for a fifth wheel
Excellent Product! Less than 10 minutes to install. A true quality product, that I am glad I purchased instead of a overpriced hitches that fills up the truck bed and is too heavy for one person to lift.
Hitch goes on easy and works great. It would be great if it came with the permanent mounting as mentioned in the instructions.
Put this on a 42' fifth wheel. Moved it from Phoenix to Missouri. Worked perfectly as expected. No issues on many of the curvy/hilly roads on SW Missouri.
I checked it repeatedly, wondering if it would loosen up at all. Nope - everything stayed tight. Thumbs up.
After install, this thing has performed flawlessly! I check it occasionally to make sure it's still tight. Hasn't budged or even wiggled!
I was looking to maximize the space in my bed and didn't want a heavy fifth wheel hitch to move in and out. I reached out to the pros at etrailer and they helped me pick the right setup. I chose to go with the Curt hideaway hitch and the Convert-A-Ball. I couldn't be more happy with their service and fast delivery.
Installed it on my camper and it works great.
This product was a great way to keep the bed of my truck clear by using my flip up goose neck ball to pull my new 5th wheel. I just got back from my first trip pulling through Washington, Oregon, and Idaho and it pulled smooth and great! I had conditions from very hilly two lane roads with 6% slopes to 75mph interstates. I do have to say that the included release lever (the one you can use from the side of the truck) doesnt make any difference because you still have to climb into the truck to remove the chains. Also my truck is a F250 which sits stock a little taller and in the lowest (12") position the trailer rides at an angle up to the truck bed (photo)so a good idea to measure closely before purchase.
I searched and searched for days to find whether I wanted to go with the fifth wheel hook up or go with the gooseneck adapter to fifth wheel. I'm still glad to this day that I made this decision to go with this adapter..It's simple and easy.. Installation was a breeze, instructions & pics to a T..Ive told everyone about this product and still talking about it I definitely recommend this product!!..
Researched several products similar to this and this was the best. Received it in a few days. Exactly what I needed for my camper. Installation was easy. YouTube video was very helpful. Will recommend to anybody.

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

thankyou for your answers
Ordered this prior to the arrival of my new Eagle RKS-313. The CAB-C5G was easy to install on the trailer, instructions were straight forward and easy to follow. One season under my belt with a Fifth Wheel, and it's been a Great one. Connect & disconnect are smooth and quick. With the hidden Goose in my Ram 3500, i have ample room for necessities to have a great week/weekend of camping. Very happy with my CAB-C5G!!
