Finding the Correct Size Fifth-Wheel-to-Gooseneck Adapter

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.


Convert-a-Ball Collar

Secure Installation

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.


Convert-a-Ball Locking Feature

Positive-Locking Feature

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.

Video Transcript for Convert-A-Ball Trailer Coupler CAB-C5G Review

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.

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. 9200 Dry. (2) 6500 lb Axels 1900 lb. on the Pin (est) If Questions, Feel free to call Have a Great Day JoeB 141891

How do you plan on installing the 4 additional bolts?

comment by: Carlos G - 07/27/2014


5932

In the installation instructions Convert-A-Ball discusses the optional installation of additional bolts. However, these bolts are available only for the customer to contact the manfucturer, and are not sold individually. To gain access this is usually done by disassembling the pin box, or by drilling access holes in the plate, but this all depends on the configuration of your pin box, and if this adapter is intended to be a temporary or a permanent solution.

Rachael H - 7/29/2014



Comments

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

I don't often write reviews, practically never. But this one deserves one. So, I didn't buy it that you could use this adapter without bolting it to the trailer. Just a sleeve around the king pin and the hitch around the sleeve. Didn't buy it. But, they guarantee it to hold as long as you install it to their specks. So I did. Here's how the story goes. I was backing my camper into a garage and forgot to make sure the door was all the way up. You can see where this is going. I hit the door. Rolled out from under the door and discussed with myself, inspected the damage. This is not the impressive part. So distracted with what I've just done, I get everything straight and continue. Now this next part is important, I drive a dually pushing out just under 700hp. I can do doughnuts or sit and roast the tires. Not that I do, but I can. I like my stuff to last. I say that so that you don't brush off the impressive part. Once I got my camper into the garage I put my truck into first and sat there with my foot on the clutch thinking about the damage I'd just done and, absent mindedly, popped the clutch. Now granny gear has enough torque to slow the rotation of the earth, and I just unleashed it onto an unbolted hitch holding my camper above my truck. It snapped so hard that it slammed my head into my seat and broke off some small shavings in my rear end. Not my butt, the rear end of my drivetrain. But, the hitch held!!! Upon inspection nothing moved! Other than flipping my truck over, I don't know how to put anymore strain on it than that. Thank you so much for building a quality product!!! I'm sold! What just cost me a few hundred dollars in parts, broken ac and garage door, could have been thousands. Thanks again. Truly, thank you. 176431

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 etrailer.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

Youd only need the offset if your truck was a short bed.

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

Good it was what I orderd just disapointed that UPS did not deliver it to my address, and not to my neighbor across the street. I was expecting the item on Friday and it arrived Thursday thanks 105988





Comments

it has worked wonderful for us. We got a pickup that can now haul both the camper and the boat So the hitch will be a great asset.It was easy to install and fit live a glove.Only downfall was UPS delivered it to our neighbors house and it took both of us to carry it to my house.

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

We ordered this and received it in 3 days. My husband and I installed it ourselves on a 1994 32 ft Coachman fifth wheel camper weighing 10,000 #s. The installation was just as the video showed. It is a really heavy and well made hitch. We are very pleased so far. It pulled just fine with our F350 crewcab duelly diesel. 149848

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 133617

Really happy with my purchase i made and a good investment. I recieved the fifth wheel to gooseneck adapter on time and next day i installed it on my fifth wheel trailer and it was very easy to do it. Instructions were plain and simple. If you dont have a buddy to help hold the adapter for you, i suggest you use a jack with a short 2x6 board to raise it in to position and begin tightneing the bolts. You do this by backing up your truck and you set the jack on the bed. I had no help so i worked with what i had... After installing it, and re inspecting everything, i took the trailer for a test drive on the dirt road and then on the paved road and it worked grea. Smooth ride, and very simple to lock and un lock the adapter from the ball. 168319

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





Comments

Rick TDoes your RV or trailer ride level with the roadway? Are the rims on your rig 18?Im concerned about the adapter making the RV ride too high in the front. Dave

comment by: Dave H - 10/09/2013

Remember this adapter is adjustable, with a range of 12-16 inches. To determine if it will work for your right you can take a quick measurement. On a flat surface, park the 5th Wheel trailer and use the landing gear to get it level. Back the truck under it and measure from the top of the ball to the pin box base, the flat surface where the king pin is welded to. As long as that measurement falls within that range, you can setup the adapter to work with your rig.

Patrick B - 10/10/2013



Comments

Little late to comment but, for new users as well as 2013 Ram owners, I have a 2013 Ram dually with the adapter that I hook to a Keystone Montana and the chains are not too short. In fact, I have enough extra chain that I have to loop them through.

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

I have a 2014 5th wheel wanting to change to gooseneck, do allmost need to be also bolted down, all seem to have predrilled holes at the neck to do so. The king pin box is a Lippert 1621. What say you. Thanks

comment by: Marvin P - 10/03/2013

So long as the system is installed properly, the collar that slides over the pin and the adapater itself will not separate from the pin. The aditional bolt kit is not needed, but can be added if desired. The instructions included with the adapter have information on how to get the bolt kit.

I AM VERRY HAPPY WITH THIS PRODUCT. DANA help me out very much with my order. This is my second hitch, i let the first one go with the old camper. only because i hated to see the new owner weld the cheap junk he brong over for his truck, also it didnt have a cushion. if you dont get the cushion your camper will beat you to death. i also love the idea that i can snap this on in a few min and go. i did drill and bolt my last one after a while only for extra security, so to say i will do this one also. (the biggest thing is i cant beleve this is so cheap) 168154

I ordered CAB-C5G hitch adapter on Sunday and was surprised that some one answered the phone when I called. I received the CAB-C5G adapter hitch on Wednesday and was again surprised but happy to get it that fast! It took very little time to install it on my 30 foot Puma Toy Hauler and it pulls great! I had bought a weld on hitch for another camper a few years ago and left it on the camper when I sold it. I can now keep my hitch adapter when and if I trade this camper for another one. I use the same truck for all my trailers and it's a gooseneck ball. 153635

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

Easy installation. Have only used it once so far to go about 400 miles rount trip up and down mountains and in some sand dunes. Didn't have any issues at all but I did notice some "jerking" when your truck is shifting gears. I have a 30ft toy hauler and it was full with toys so I just attributed it to the weight of the trailer pushing me forward while the truck was shifting and then the truck tugging back right after it shifts. It's very subtle but was enough for me to notice. Not sure if this is normal or just my setup... 214105

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.

Well, I haven't installed it yet, but I can say that the customer service was excellent. I called in to ask a few questions that I was unclear on. Deborah H. answered all the questions I had, and then placed my order. She then emailed me directly to let me know when it had shipped, and even emailed me to let me know it arrived at my house. Customer service like that is hard to come by these days. I hope the performance of the unit is as good as the customer service. I should know soon! Thanks 208132

This was a clean and simple design that is easy to install. The video and instruction sheet made the install easy. Once installed, the unit made hook up and towing easy. The frustrating part about this is the use of square head bolts. They require the use of a crowfoot wrench to adapt to a torque wrench. These are not easy to find, and they are relatively expensive. Manufacture the bolts with hex heads instead so that a standard 1" socket can be used. 128798

So far so good. Got the adapter as scheduled and installed it in about 30 minutes with the help of a friend and a pipe jackstand (just so I didn't have to hold it up the whole time. Haven't had a chance to road test it just yet, but it appears to be an extremely well built solution to not having the bed of my pickup full of a fifth wheel hitch. I'll try to update after I pull with it for a few hundred miles. 161684

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

Absolutely outstanding product! I'll admit I was a little worried about using this type of adapter at first but my worried eased a bit when I saw how heavy-duty it was. My fears are completely gone now that I've towed my trailer over 400 miles on highways and off road through the mountains. It makes for a VERY solid, comfortable tow and I recommend it wholeheartedly. 142500

A great product,Install was fairly easy. However, I don't like the square bolts that secure the housing to the king pin collar. Couldn't get a 6 point 15/16 socket to work,but the 12 worked fine. Overall, I would recommend this to a friend. I haven't pulled my 33 1/2' Nu-wa Hitchhiker yet, so maybe I will write another review after I hit the trail. Happy Hookin!!! 176347

Shipped and received in a very short of time, put in on the trailer after I bought a torque wrench, which I needed any way, hooked it up to the truck and it fell right in place after a few attempts aligning it up, have a tool box in my line of sight, have not towed with it yet, seeing how it's winter here, but don't foresee any problems. 171421

I installed the convert a ball on my fifth wheel trailer, now I have a back and forth motion as I pull it, any suggestions.. 49587

I have the same problem. Instructions do not say to drill and tap, but I an considering trying this to see if it stabilizes the ride. Any other suggestions?

It will take some extra work, but it may be worth removing the coupler and making sure the collar is installed properly and then re-install the coupler. If that does not resolve the issue, I would contact Convert-A-Ball.

Again, removing and verifying the collar install or re-installing it my help. Beyond that, a call to Convert-A-Ball may be in order.

I was blown away by how easy it turned out to be to install the adapter. I am a do it yourself er and very accustomed to running into significant issues on projects of this type. My 13 year old granddaughter and I installed it in less than 30 minutes without hick ups. I would recommend it to any one. 203540

Very well thought out product. I installed this hitch and drove the trailer 4 hours in the rain and never felt unsafe or uneasy about the stability. It takes less than an hour to install and very straight forward. I would recommend this product to anyone looking to convert to a gooseneck hitch. 176345

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

Do you have a question about this Gooseneck and Fifth Wheel Adapter?


  • Gooseneck vs 5th Wheel Hitch for Towing My RV Fifth Wheel Trailer
  • A gooseneck adapter that is designed for towing a fifth-wheel trailer, like the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter, # CAB-C5G, is normally used when a person already has a gooseneck trailer hitch installed in the truck and needs to tow both gooseneck and 5th wheel trailers. These adapters are a good solution, but do not provide as nice a ride when towing a fifth wheel trailer. If your truck does not have a hitch installed I would recommend going with a fifth-wheel...

  • Best Way to Tow Fifth Wheel Trailer With 2014 Dodge Ram 2500 With Factory Tow Prep Package
  • In my opinion, the best way to tow a fifth wheel trailer with your 2014 Dodge Ram 2500 with the OEM fifth wheel prep package is to use a fifth wheel hitch that fits the in-bed pucks in your truck bed. You have several hitch options that will work, but my favorite is the B&W Companion 25K Fifth Wheel Hitch, # BWRVK3600. This hitch will drop right into the pucks in the truck bed and once it is removed, you will have full access to your bed. Curt also makes fifth wheel hitches for the...

  • Can the CAB-C5G 5th Wheel to Gooseneck Adapter be Used without Bolting or Welding to Trailer Pin Box
  • Yes, you can use the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter, # CAB-C5G, without bolting it to the trailer king pin boxes. This is the best option for this coupler because it allows you to tow different trailers without the need for modification to the trailer pin boxes. This also makes the adapter fairly easy to move from trailer to trailer. One thing I would like to mention is that any of the offset adapters for short bed pickups, like part # CAB-C5GX1216, will require...

  • Concerns About Towing a 5th Wheel Trailer with a Dodge Ram 3500 Equipped with a Goose Neck Hitch
  • There are several ways to adapt a 5th wheel trailer to enable it to be towed with a truck that has a goose neck hitch installed. The best choice for you will depend on how often you need to change between trailer types. Some of the adapters that allow this flexibility will put more stress on the trailer frame than other types. Options are still somewhat limited for newer vehicles like your 2014 Ram. A fifth wheel adapter that bolts onto the king pin, such as Convert-A-Ball # CAB-C5G...

  • What is the Minimum Clearance Between Truck Bed Sides and the Bottom of a 5th Wheel Trailer
  • A good rule to follow is to allow 6 inches or more of clearance between the sides of the bed and the bottom of the 5th wheel trailer to allow for dips and bumps in the road. To find the right 5th wheel to gooseneck adapter for your truck and trailer, there is a simple measurement you can take. First, back your truck into position as if you were hooking up your fifth-wheel trailer. Make sure that the truck and trailer are level. Next, measure from the pin plate (the bottom of the pin...

  • Ride Quality and Safety when Using a 5th-Wheel-to-Gooseneck Adapter with a 32 Foot Trailer and F-350
  • The reason that ride quality suffers a bit with a gooseneck adapter like part # CAB-C5G, is because the fifth-wheel trailer pin box and framing are designed to be towed on a fifth-wheel hitch. The extra distance down to the gooseneck ball in the bed of the truck causes torque on the trailer chassis which in turn causes the pin box and trailer frame to flex, which contributes to what is know as chucking and bouncing. This issue can be worse with some trailers and hardly noticeable with others....

  • Will Fifth Wheel to Gooseneck Adapter CAB-C5G Work with a 33 Foot Holiday Rambler
  • The adapter will bolt attach to any standard Fifth Wheel king pin, but you will need to take some measurements to be sure it will fit. After backing the vehicle under the trailer, measure from the top of the ball on the truck to the base of the pin box on the trailer. The adapter we carry is adjustable between 12 and 16 inches. Please note, that these adapters are not to be used in trucks with less than a 6 foot bed. Also note that these adapters are not meant to be used permanently....

  • 5th-Wheel-to-Gooseneck Trailer Hitch Adapter Recommendation for a Toy Hauler
  • You are correct in that some gooseneck hitches have weight ratings that will handle up to 26,000 pounds or more. However, if you use this adapter, # CAB-C5G, you have to abide by the lowest limiting factor. For instance, if you had a heavy-duty gooseneck hitch and then used this adapter to pull a fifth wheel trailer, the adapter would be the limiting factor of 20,000 pounds towing capacity and 2,000 pounds tongue weight capacity. If you are trying to tow your toyhauler fifth wheel with...

It cannot be used with a trailer ball mounted to a draw bar installed into a rear mounted receiver hitch. Your best bet would be to install a fifth wheel hitch in your truck bed.

  • Using a 5th wheel to Gooseneck adapter, like the Convert-A-Ball Multi-Cushioned 5th-Wheel-to-Gooseneck Coupler Adapter, # CAB-C5G, can apply added stress to the trailer frame. You will need to contact Keystone to determine if the trailer can be used with a 5th wheel to gooseneck adapter. The biggest drawback will be a decrease in ride quality. If the trailer has an extended pin box or requires additional support, reinforcement of the trailer frame will be required and should be performed...

I have attached a video below showing installation to give you a better idea of how the Signature Series works. If you wanted to go with a gooseneck, you could use something like a Hide-A-Goose.

The adapter is rated up to 20,000 pounds gross trailer weight and you are well under the limit. Just make sure your king pin box on your trailer is no longer than 30 inches from the center of the king pin to the center of the the mounting bolts.
