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.

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.
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.
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

Joe, what is the box length of your Ram?

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.
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
Installation was easy. The product has performed very well. I would recommend this conversion for anyone who needs to convert a kingpin fifth wheel on a trailer to a gooseneck hitch.
Hitch just installed on 5th wheel. I think you should have included a tool for the 3/8" allen screws and the 4 bolts & nuts. I live in a rural area and had to do some serious hunting for the allen screws, which translates to a lot of wasted time. You should put in your instructions to predrill the holes before installing the hitch. Will have to remove hitch to drill bolt holes. Product looks great, will do truck hookup in a couple of days. Don't expect any problems
Great ADAPTER HITCH!!!! Even though the hitch didn’t call for them, I drilled and installed the 4 bolts, for EXTRA SECURITY, and “Peace of Mind”
Watched the tutorial video on installation, 3/4” 8 point socket doesn’t fit the square head bolts. My question…why not just switch to a standard (or metric) bolt rather than square head? I’ve never seen a square torque wrench yet it says torque it to 120.

You arent alone in finding the bolts frustrating, and I wont say its not a pain. It looks like you need a crowfoot wrench adapted to a torque wrench. I have heard of others using a crescent wrench as well.
I bought this fifth wheel adapter a year ago when I purchased a 2006 Keystone Challenger camper. It's a bigger camper (35 feet) so I put in the extra bolts right away. I pull it with my 2005 F350 with a chipped 6.0. I check it over before every trip and haven't noticed any wear or loosening. The real test will come in September when will travel from Wisconsin to Glacier.
Product and Service was great. The Adapter has made moving our 2006 Keystone 5th Wheel around a lot easier and have noticed no issues. Great Product!
I bought this to convert my fifth wheel trailer to gooseneck so I did not have to swap the fifth wheel hitch into the truck every time we wanted to take the RV out. Instructions were very clear, installation went very well, and it has held up very well in the year we have used it, probably 7K miles all told. One thing I did not anticipate was that the landing gear motor on the RV would have to work overtime to lift the coach off the gooseneck ball, and then lower the coach down to level it on a parking pad. It's a bit inconvenient, and I suspect the lift motor may suffer a shorter life, but it's a small price to pay for not having to forklift in that fifth wheel hitch every month.
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!
Very well made adapter. Was reluctant to put on a gooseneck adapter do to the naysayers but I went ahead and purchased one and I couldn’t be happier. I installed the adapter in less than 15 minutes. I did have the needed tools on hand so that most definitely made install much easier. Pulls my 5th wheel perfectly. Highly recommend.
Adapter works well. Pickup has gooseneck balls socket so not as much space taken up by regular gooseneck hitch that needs removed when not using
This piece is great! I don’t have to drill any more holes in the bed of my truck to install a 5th wheel. Easily installed in about 30 minutes. I will recommend this to anyone that asks. For those looking to get one, here are the tools you’ll need to install: 19mm crowfoot 1/2” drive, 27mm crowfoot 1/2” drive, 3/8” hex 1/2” drive and a 1/2” drive torque wrench. I installed it by myself. I just back the truck underneath and lowered the kingpin down onto the adapter, after installing the kingpin ring.
Tech guy was very helpful. Worked as should. Did have to re tighten bolts after first trip Added a bolt to hang safety chains on. Would have preferred different type of hook on safety chain. But all and all just what I wanted and needed at a good price
Shopped around a bit before finally ordering from etrailer. Price was nearly $xxx lower than everywhere else I've looked, and only took 2 days from order being placed for it to arrive. Exactly what i needed to replaced the coupler that came on damaged on my trailer!

Gooseneck adapter still works great, couldn’t have picked a better product to pull out camper and not buy a 5th wheel hitch
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 seems to be a very quality part and install directions were great. My only comment is they should include the bolts to mount to king pin in box as I drilled,tapped and installed bolts to make it a very secure install. Have not had a chance to tow it yet
Can’t say enough good things about this order. Shipping fast and perfect instructions absolutely satisfying
Well built product for added strength I drilled and tapped holes for mounting flange.I did flatten surfaces for the head of bolts is was at an angle.it’s on a 30ft with 3 slides and pulls very well.
I don't really know much about this. I'm new to all this but the old 5th wheel I was given needed it.
The hitch was delivered ahead of schedule and etrailer provided up to date information regarding the delivery. The product works as it should. Very satisfied with the transaction.
Damn good, instructions are easy to put on. Wife tightened bolts while I held it up, it fit like a champ. Going to haul 30' toy hauler to the rocks this weekend and tighten bolts again. If all goes well I will write again. Fast delivery and very robust good adjustments made the trailer as flat as possible with my flatbed, bed is a bit tall.
