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.
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.

Today were going to review part number CAB-C5G. This is the Convert-A-Ball cushion fifth wheel to gooseneck adapter. It is height adjustable from 12 inches to 16 inches and it has a 20,000 pound towing capacity. This fifth wheel to gooseneck adapter will let you tow your fifth wheel trailer with your gooseneck hitch. This coupler bolts to your trailers kingpin and then itll connect to the gooseneck ball in your truck bed. On the inside they do have the polyurethane cushions which will act as shock absorbers for a smooth, safe ride.
They help reduce bounce and vibration and theyll minimize the wear and tear on both your trailer and your tow vehicle. This does have adjustable height which I can show you right here. This will slide up and down for adjustable heights which will fit many applications. It is a fail-safe kingpin adapter. It has a built in positive lock feature to secure the trailer to the hitch ball.
The steel extension handle lets you slide this bar to lock or unlock the coupler from the outside of the truck bed and itll act as a latch by keeping the adapter secure. This part is made of a durable cast steel construction. It does have a rust resistant powder coat finish. It does come with the safety chains which are included. Comes with the locking collar and again the steel extension handle.
This part is made in the USA. It does have a towing capacity of 20,000 pounds. It has a pin weight capacity of 4,000 pounds and it does fit on a 2 5/16th gooseneck hitch ball. Again the height is adjusted from 12 inches to 16 inches. It does come with a two year limited warranty.
First off I want to show you how youd actually install this onto your fifth wheel and your gooseneck. Basically you would start off with this locking collar. It has three large Allen head bolts in it and theres also three indentations. Basically what you would do is on it it says, Top front. So this is the top front right here. Then this white locator mark here is where youll line this up to the exact center on the front of your kingpin box. This would basically slide up onto your kingpin and then you would tighten these Allen head bolts down to where they will rest on the bottom lip of your trailer kingpin. Snug them up and then this would be secured on your kingpin on your fifth wheel. Then this coupler right here will basically slide up onto this collar right in here. It would slide up on here. These three jam nuts right here at the top will actually tighten down into these indentations on the locking collar and you would torque them down to hold it into place. Now on this adapter as you can see right up here it says front, right here it says front. This will basically face your truck cab. This would be pointing towards the front of your truck which would make this locking handle on the drivers side of your truck bed. With this already installed onto your fifth wheel trailer you will slide this up on to the locking collar, torque down these jam nuts right here, and that would secure it into place. Your next step would be to slide this down over the gooseneck ball in your truck bed and then you can adjust the height to where you can see. Right on the back here there are three jam nuts that will tighten down once you get your height selected. Basically this would slide up and down to get you the correct height. One of the things I just wanted to show that youll see when I slide this up too far youll see a red line become exposed. You do not want that red line showing. Thats actually a warning that you do not want to hook it up that way. Anytime you adjust your height you want to make sure that red line is covered up. That it is not showing. If you see that red showing that means you need to lower your trailer until there is no red showing before tightening any of these jam nuts. Then the other feature I wanted to show you was this right here. You slide this to open; its stamped open here, and locks here. If you slide this to open then you would slide that down onto your hitch ball when youre doing your height adjustment. This extension handle is nice to use because you can be outside the truck bed and you can use either end. You can just reach in, move it to the lock position, move it to the open position. Once you move it into the lock position its locked over the gooseneck ball then you can use this other end, the hooked end, as a positive lock feature. Basically what youd do is theres a hole right here, youd slide this hook end from the inside out and then make the extension handle go behind and then just drop this down into your truck bed. It would actually lock this latch from going over to the open position so it is a positive lock feature. Now if you do want greater security you can run a padlock through here which I sold separately and thatll give you greater security to keep this latch from moving to the open position. That should do it for review on part number CAB-C5G.

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. 85769

Great product! Install was quick and easy. Despite the weight I was able to install by myself in less than 20min. The adjustment is a nice feature as well. 106860

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. 35775
by: Dawn S.05/01/2012
Great service and quick delivery! Arrived on my porch three days after ordering. Needed to convert a 5th wheel camper to a gooseneck hitch, since we regularly haul a horse trailer. Installation took about 1/2 an hour and directions were clear and concise. Thanks for a quality product. Will highly recommend your site! 38916

We bought a 2001, 29' Keystone Montana 5th wheel,pulled by a 2008, F-450 with a gooseneck ball in the bed. I researched between the typical 5th wheel mount and the gooseneck conversion. YOUR videos and website gave me the most information, was clear even for a newbe like me and sealed the deal. The dealership that I purchased the 5th wheel from had never heard of this product and wanted to charge me about $125 installation for theirs because of the need to drill and weld. I told them about your product, gave them the You Tube and etrailel.com link. I bought yours and had it delivered to my house. The dealer was amazed at the ease of putting the unit on the 5th Wheel hitch and didn't charge me anything for the labor. I think they will be ordering product from you! Anyway, we have used it for only 2 weeks, it seems perfect in every way. Thank you so much for the ease of ordering, understandable videos, great website and order followup. The only suggestion I would have is to explain the difference in purchasing an offset unit vs. straight (like the one I bought) I was a bit jumpy about not knowing specifically which one I needed and why. Thanks for the great work, I am extremely pleased and I have been telling everyone about your company!!!83825

The adapter was very easy to install and adjust. This will allow me to test drive different trucks with my fifth wheel camper that have the gooseneck ball. The instructions were very easy to follow thank you97031
by: Heather Jones02/26/2014
The customer service when buying on line is usually lacking BUT... this has been a great experience with etrailers! We have received no less than three emails letting us know every detail along the way. Thank you so much for that piece of mind that was unexpected but VERY appreciated!117826
bolted on really easy and fast and you can switch back to a 5th wheel setup in 10minutes , you don't have to drill into your kingpin box witch every other adapter I looked at you had to do its really safe I work the oilfeilds I towed my camper 100 miles when I first got it most of it old log roads and it did great the camper dosnt wobble at all witch surprised me I thought it would compared to a 5th wheel set up, as always etrailer shipped it very fast and it was perfict when it arrived I've never had trouble with etrailer 114116
by: S. Fuller08/12/2013
This adapter was very easy to install. Was able to do it by myself in less than 30 minutes. Even thought you don't have to bolt this adapter to the hitch plate, the instruction say that a bolt up kit is available and free of charge. I would recommend this product. Also shipping from etrailer was very quick, and the price was right after shopping around.94543
by: Rick Truelove07/11/2013
Set up was as simple as advertised. I was able to do it by myself. Only problem I had is the new 2013 Ram 3500's, the 5th Wheel/Gooseneck factory pre-installed tow package the safety chains are too short. I will have to buy some new chains to fit. I have not towed with it yet, but will post another review after I do.89036
by: keith h06/17/2013
I bought a newer pickup that had a ball in the bed of the pickup. I purchased your convert-a-ball adapter, and used it last weekend for the first time. I was very pleased with the ease of installing it. my wife and I did it ourselves. It worked perfect. I feel very safe pulling our heavy rv, and using the convert-a-ball. Thanks for your great invention. It was as good as advertised, and more.84930
by: Gary A04/16/2013
Product was easy to attach and worked like a charm. Had no issues and it seems to be of good quality. Would recommend to anyone that needs to pull a 5th wheel with a gooseneck. Glad I found this product.76417
by: John R.07/07/2012
I just bought a 30ft 5th wheel. I went to pick it up and It took more time to lift the jacks on the trailer than it did to install the gooseneck adapter. It pulled as good as any gooseneck trailer I have pulled. It only required an allen wrench and a cresent wrench to install. The instructions were simple and easy to follow. I could not be more happy with this product.47047
Air ride is the way to go. We got this adapter for a 5th wheel camper, the air ride makes it less noticeable than our gooseneck and I didn't think that was possible. I would highly recommend, took less than 10 minutes to put on, easy release couldn't be any easier!1129
by: Matt P.12/18/2011
After watching the very informative youtube video, we decided to purchase from etrailer. Our hitch arrived 5 business days after ordering, took 10 minutes to install and worked perfectly bringing our newly purchased 5th wheel trailer home. 28252
