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. Because this adapter is designed with an offset, the top lip of the adapter must also be bolted to the base of the pin box to ensure proper positioning.
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.
This coupler adapter is specially designed for use with truck beds that are between 6 feet and 8 feet in length. The offset allows your trailer to sit a bit farther back than it normally would so that you can make turns safely and with confidence. Supplying that extra space between your trailer and truck cab creates the clearance necessary for you to make tight turns without your trailer hitting your cab.
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.

Use your gooseneck hitch to tow your 5th-wheel trailer by hooking up with this coupler adapter. Poly cushions absorb shock for a smooth ride. Adjustable height fits multiple applications. Offset design is perfect for short-bed pickups. 20,000-lb GTW.I ordered a 5th wheel to gooseneck 7 1/2" offset adapter. I didn't receive it for 10 days due to weather delay. When I did receive it I've got 2 of the same item, The boxes were labeled incorrectly. Now I have to go through the problem of sending the extra one back and wait on the correct item to be delivered, I sure hope there are no weather delays, I need this SOON! Other than this issue I have always had good experiences with ordering through etrailer. I will also do a follow-up review when I receive the correct item.
Katrina B - 04/18/2022CAVEAT EMPTOR! Don’t cheese out - get what you really need
Not appropriate for every application but the information provided does not make it clear
Great product!I had a couple concerns and the people at convert a ball were very courteous and knowledgeable. They addressed my Conan’s it works beautifully.
Phillip - 06/20/2022This is my first 5th wheel but I have several other gooseneck trailers that I tow on a regular basis. I didn't want to have to switch back and forth so I bought this adapter. I have a long bed but I have a chase rack on it that goes up over the cab. I really didn't want to have to remove it every time I wanted to tow my new toy hauler so I got the offset hitch. Install was very straight forward. Took me about 40 min. to install. The hardest part was getting the bolts in as mine has the long pin box and it was all I could do to reach the holes. I don't have very many miles on it but it tows great. I didn't notice any difference from my other gooseneck trailers.

I have a short bed so I assumed the offset was needed for cab clearance. The off set has a major design flaw. It needs to be drilled through and pinned or welded to prevent it from rotating while backing up. Trust me, we tightened the bolts to the point of denting the post and it still rotated while backing up allowing it to strike my bedside causing significant damage. The offset went in the trash and I used the large flanged adapter successfully after that with out the offset. I then discovered the late model 2018 trailer had plenty of room and cleared the shortbed cab with out the offset anyways! I was trying to fix a problem that didn't exist. Some days you can't win. lol..
Sorry, I can not recommend the offset with out pinning or welding it. But the straight Goose neck adapter works fine.
Jenny N - 11/18/2021I received this hitch about a year ago, it arrived with in a week of ordering it. The instructions were simple to understand. It did say it will take two person to install. I was able to install it by myself with in a few hours, What I like about this hitch is that I still have use of my truck bed when unhook when traveling and I don’t have a fifthwheel to haul around. My camper pulls great with this hitch with no complaintion at all. It’s a great hitch.
I could not use it on the new 5th wheel I bought. Still have it and I am trying to sell it.
Bought this to convert 5th wheel camper to gooseneck. Hardest part of the install is drilling and tapping the holes to attach to kingpin plate. But once finished and used for the first time, absolutely love it! Camper pulls much smoother than when it was 5th wheel
worked excelent for the year that i owned this trailer. sinse have sold the whole traler and this hitch and was a definite point of sale to the new buyer. thanks
Jarrod - 01/26/2022I have ordered many items from etrailer they always arrive fast this gooseneck to 5th wheel adapter installed easy and did the trick for me built very strong. The staff at etrailet is always very helpful.
Owned a year now GREAT product.
Made very well. Installed in 40 minutes in dealership parking lot. Trailer towed beautifully thanks to cushion in system.
This hitch adapter is heavy duty. It's easy for two people to install in under an hour and all parts fit together well. The instructions were well written in English, which is the official language of our country (USA). The offset adapter works great with my 2011 Ram 2500 4x4 which sits higher due to oversized tires. My shipment was received two days after I ordered it without paying any expedited freight charges!
Thanks to the Convert-A-Ball and the fine folks at etrailer.com my days of listening to a clanging 5th wheel hitch are over. Thank you etrailer.
Roger was very helpful! He went the extra mile to find exactly what we needed. it wasn’t easy! We haven’t traveled with it yet, so we can’t comment about that, but Roger was very helpful to us when we were about to decide there was no solution!! it’s people like this that bring return customers!!
Easy install, great looking and excellent quality
Wow what a great product! Instructions were great and very easy to install. I did it by myself in under a half hour. Looks very strong and better than expected. Arrived in just a few days.
Delivery was ontime and great service. Item was heavy duty as advertised and good quality
I was not explained about having to drill holes in my fith wheel hitch. This was difficult to do and when done it was not level, very difficult to take trailer off truck, had to use a jack. I had to redo and had to add spacers between fithwheel and gooseneck. This might have been better if I had not got the 7 inch offset, this tended to pull the bolts out of the fith wheel platform. I had to redo this hitch three times.
Awesome customer service. Way better than average shipping.
I bought this adaptor about a year ago and I have to say it has been worth every penny that I paid! I have an 8ft bed with a tool box in the back so having the offset worked great, giving me more ability to turn the trailer right where I needed it to get. Install was fairly simple but you'll want at least 1 more person to help since it weighs almost 90lbs. Have a torque wrench handy to. All in all I recommend this to anyone who has a gooseneck ball in the bed of their truck who wants to own a 5th wheel trailer!
So far so good. The order was processed perfectly. I just got the Convert a ball cushioned 5th wheel to goose-neck adapter with offset. I haven't even opened the boxes yet but when I do I'm sure I will have the same sense of satisfaction I get whenever I open something I've ordered from E-trailer. My satisfaction level right now is 100%. I will share photo's of the install.
I wish I would have installed this years ago. Took it on its 1st trip up the Northern Coast of California, pulled so nice, and when we got to the camp ground I had nothing in my bed.
I installed it by myself in about 2 hours, took it off and on about 4 times. It took me the longest to tap the threads 2 of the bolts I could get the nuts and lock washers on but 2 had to be threaded. I had drill bits and taps so that was a no cost, I would suggest that if you have to thread holes go buy good drill bits and a tap, do it right.
After it was completed and I did a test drive backed it into my side yard and I could not get the trailer off the ball, I thought it was stuck, it was not I just didn't notice how much the cushion travels I thought I was lifting the trailer to high.
Anyhow I love it and it was reasonably priced.
Easy to install. Super easy to use. Hook up is so simple and fast. Best purchase that I made after buying my 5th wheeler. This Convert a Ball Gooseneck and Fifth Wheel Adjuster have not weathered at all over the last year. They are both still in prime condition, no rusting.
After installing the gooseneck, hooking it up to trailer, I was not impressed on the function of this gooseneck(recommended for short bed truck).
Towing my trailer was like pulling the entire railroad pacific behind me.. Lot of tugging jerking. When I arrived to my destination the gooseneck had dropped down in the front giving it a dropped and sideways location instead of the installed and aligned position... Gooseneck was rated for up to 14,000 pounds.. I was towing only 9,000.. My vehicle struggled even though it is a GMC 2500 with all the gear......
I like it. Installation was simple! The adapt-a-ball allows me to tow my fifth-wheel camper without worrying about knocking out the back window in the cab and I didn’t have to install a fifth-wheel plate. A friend asked about it and later bought one on my recommendation.
The CAB-C5GX1216 was the perfect fix for my situation, I have a 1997 Dodge ram 3500 Flatbed with a goosneck , i went with this so that i would not have to do away with my goosneck , and to give me more clearance for sharp turns. I would recommend this to anyone that uses a goosneck alot like i do, I had it installed in about 1 1/2 hours. The CAB-C5GX1216 is really well made. Really fast shipping and great service super nice people. What ever you buy from Etrailer you know that you get a great product and a great price. Thanks for all you guys do at etrailer
