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.

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

How do you plan on installing the 4 additional bolts?
-- comment by: Carlos G - 07/27/2014

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.

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.

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.


Comments
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!

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.


Comments
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 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

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. Walter, R


Comments
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.

After installing this adapter I noticed it was flexing the frame of my trailer. The added stress from the adapter is more than the 5th wheel pin box was designed for. It didn't say anything about this in the product description. I called etrailer to see if I could exchange the adapter for a proper 5th wheel setup and they told me because I had used it once they couldn't help me. Be careful with these things, your trailer may not have been designed with them in mind.

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.

by:

Installation was a breeze. This is a very heavy duty unit. First tow with our fifth wheel and it worked great. I have used cheaper units in the past and this product definitely surpasses those. I would recommend for anyone wanting to utilize the fifth wheel ball instead of a full out fifth wheel hitch.


Comments
Works great no issues after a year of use.. One con to the hitch is having to be exactly lined up to hook it up. Not usually a problem with a helper.

Product arrived as described. Was very easy to install, took about 30-45 minutes including reading the instructions. It would be nice if the bolts to secure the hitch to the collar, as well as the bolts used to adjust the height were a standard bolt head vrs a square head. Other than that very easy & straight forward. I like this adapter much better than having the traditional 5th wheel hitch taking up room in the bed of my truck.

Bought a truck with a heavy duty gooseneck hitch. Found a fifth wheel we wanted to buy. I ordered the CAB-C5G with 3 day shipping. It was here in 3 days! The unit was very heavy and the packaging was very well done. I read the instructions and gathered up the tools needed for the installation. We drove about 125 miles with it still in the box not knowing exactly what was going to happen. The seller and I took about a half hour to install it on the trailer and a few more minutes to adjust it in his driveway. Once we got it out on the road we noticed the trailer was front high. We took about 20 more minutes in a parking lot to make the final adjustments. My truck is a 2011 GMC 3500 single wheel so it is pretty high. On the road we experienced no problems on the 125 mile trip home. I was a little skeptical about how this would feel going down the road but after a little while we were doing the speed limit at 70 mph on route 93 South in NH coming out of VT. We stopped after 50 miles or so to check the torque on the bolts and it was fine. This adapter was supposed to be a short term fix until I could figure out a fifth wheel setup with the given hitch, but I think I just may like this on a longer term. With the fold over ball, I can use the bed of the truck without having to remove a big heavy hitch. This adapter is HEAVY DUTY, emphasis on heavy! Hooking up you have to have the trailer a little higher than normal to clear the ball height. Also yo do not have the luxury of the 5th wheel to guide you in if you're a little off. Mostly pros with this unit, can't come up with any cons. Great product and I would recommend it.

the hitch arrived in 3 business days as promised via UPS. It weighing over 70 pounds I expected the cardboard box to be thrashed. The box arrived in perfect shape, great job on packaging . I immediately ran out and and began installing it on my trailer. Things went terrible, I had the white line on the collar facing forward per the video and the instructions; it just wasn't lining up when I slipped the hitch up. Plus it would not go up and seat to the king pin plate. I called customer service and they were going to have a technician call me. I started taking the collar off and that's when I discovered I had installed it upside down?? I flipped it over reinstalled it and the rest of the installation went perfect as per the instructions. If I had not of made that error the whole thing would have only taken about 15 minutes. I felt kinda stupid because the collar is stamped this side up and has an arrow. None the less I called customer service back and told them of my error and cancelled the technician callback request. Great product, love the additional bed space I gained by going to the turnover ball with the etrailer adapter.

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!!..

Just received the hitch Some of this must be UPS but you guys might need to up your game in the packing department. I can't imagine this hurting this chunk of steel so I'm not too concerned. I have opened the box and all looks good. It would help to have listed out wrench sizes needed for installation prior to receiving the item. That way I could be prepared if I don't own the right sizes. Thankfully I'm old and have many tools younger people don't have. I do have what is needed in my tool box. I did appreciate the videos online. They made me feel much more confident in my abilities to install this product with safety. I own a Ram3500 longbed and will be pulling a 2014 Jayco Eagle 35' 5th wheel. GWV 12060 unloaded. My truck came to me with a Gooseneck hitch built in and I do use the bed on a regular basis. Getting an adapter seemed the logical direction. I did receive a 5th wheel hitch along with the trailer and am planning on keeping it till I know I'm happy with the adapter. Now for installation... I'll need to report back after that is completed. So far I'm going with 3 stars as I withhold my true assessment till I am done and have driven this beast.

We just installed and pulled a 5th wheel toy hauler 400 miles!! A what a great product, converter was heavy duty, 1 1/2 hours to install and set up. We have been pulling a goose neck horse trailer for years and was so happy that this adapter enabled us to haul this new trailer without any problems. The toy hauler (10,000 lbs empty) pulling was great and tracked straight, even with the 25+ miles per hour of wind all the way home. Just went between 55 and 60 miles per hour no problems. We are pulling the trailer with a 1999 F250 Superduty. Also have to say that etrailers customer service, especially Kim P. was the best!! They now have a new customer for life!

Really like it gives me more room in the bed of the truck with my hidden hitch. Saves a lot of time and work it’s heavy....it. Costs more than competitors.. but wouldn’t want to trust my safety with a Walmart brand converter hitch just to save a dollar. Short story long I am pleased with my purchase.

by:

The gooseneck adapter was very easy to install and works and hauls well. I prefer to haul my fifth wheel with this adapter vs. a fifth wheel plate so I have less holes in my bed and my bed is flat. I have noticed my 2016 Chevy 2500HD rides rougher when hauling. I would recommend this product to someone that wants a cleaner bed and does not want to keep moving their fifth wheel plate in and out.

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

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.

Just used this to tow a 30ft 5th wheel using an in bed ball mount. it was super easy to install and set up. I did find the 3 bolts holding the collar on were a little loose after a short tow, so Id recommend re torquing them after towing a few miles. Seems really solidly built and will hope to use it again soon.

1st trip out and it Worked Great!!!!!!! Very easy to install Little harder to line up and hook up then a regular fifth wheel hitch. But well worth it for not having that big hitch in the truck box. No more putting it and taking out after every trip. Would highly recommend this..

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.

  • 5th Wheel To Goose Neck Adapter For A Trail Air Roto-Flex Pin Box
    To convert your 2015 Sabre 5th Wheel to a goose neck would require removing your Roto-Flex Trail Air king pin. There is not a goose neck adapter that is compatible to work with this king pin because the Roto-Flex king pin plate pivots. A goose neck adapter like Item # CAB-C5G works the same way when connected to the ball. Having two pivot points, at opposite ends of the adapter, would cause over extension.

  • Adapter Recommendation to Go From Leland 7921 Pin Box to Gooseneck Hitch
    I wish we had a Reese Goose Box that fit as a replacement for a Leland 7921 but at this time we do not. Best alternative we have would be a Convert a Ball adapter like part # CAB-C5G. This attaches to the pin box of the trailer you plan on towing and gives you a gooseneck coupler to attach to a coupler.

There is simply too much movement for the adapter. The better option for that application is the Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter - Single Jaw - 21,000 lbs # DM8550045. This will fit directly over your gooseneck ball and will give you an adjustable height hitch with 3 height settings...

  • Can a Gooseneck Adapter be Used on a Trailair Air Ride Pin Box
    You can use the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter # CAB-C5G if you change out your pin box, but unfortunately the Trailair Air Ride # UF35-946215 that you have cannot be used with a gooseneck hitch adapter. We do have some options for you to use a 5th wheel hitch like the B&W Companion # BWRVK3500 in a B&W gooseneck hitch but I would need to know what brand gooseneck hitch you have to verify a fit.

  • Torque Spec for Collar Bolts On Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter
    In regards to the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter part # CAB-C5G, there is no torque spec for the hex head bolts on the collar. I spoke with Convert-A-Ball and they informed that the bolts need to all be flush and evenly tightened but that is all because there is again no torque specifications for these bolts.

  • Recommended 5th Wheel Adapter for Recessed Gooseneck Hitch on 2006 Dodge 1 Ton Dually Flat Bed
    Since the gooseneck hitch is recessed we have limited options. Normally a recessed gooseneck hitch in a flat bed offers very limited clearance, so I recommend the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter - 12" to 16" Tall - 20,000 lbs # CAB-C5G. This adapter will give you an adjustable height from the top of the gooseneck ball to the base of the king pin of 12-16 inches. Another option is the Ranch Hitch Universal 5th-Wheel-to-Gooseneck Coupler Adapter # AM3100, but...

  • 5th Wheel King Pin to Goose Neck Ball Adapters for Lippert Rhino Pin Box
    I have a few options for your consideration. We do not have a replacement pin box for the rhino currently. First is the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter # CAB-C5G. This will bolt to the king pin on your 5th wheel trailer and connect to the gooseneck ball in your truck. This kit is recommended for 8' bed trucks. Second is the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter w/ Offset # CAB-C5GX1216. This is the same as the above but features an offset...

  • Can the Convert a Ball Fifth Wheel Adapter be Used on a Mor/Ryde Pin Box
    I spoke with my contact at Convert-A-Ball and he informed me that you would totally be fine using the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter w/ Offset # CAB-C5G on your trailer with a cushioned Mor/Ryde pin box. The two sets of cushions will work together to provide you with a very smooth ride.

  • Can Gooseneck Adapter for Lippert Turning Point Pin Box for Nissan Titan XD
    The Lippert Turning Point pin box actually has a unique pin box mounting bolt hole configuration so it cannot be interchanged with another pin box, like the (discontinued) Reese Goose Box, but I do have an alternative solution for you. If you lockout the Turning Point pin box it then becomes a standard pin box and you can use an adapter like the Convert-A-Ball # CAB-C5G to make it compatible with a gooseneck hitch ball on your Nissan Titan XD. Please note that this will move your...

  • Fifth Wheel Hitch to Gooseneck Adapter Compatible with Lippert Rota Flex Pin Box
    My contact at Convert a ball explained that this adapter is not compatible with Trail-Air's Rota-Flex pin box. This is due to the forward and rearward movement in this pin box like what you have found. Your setup is not safe unfortunately. You could replace the pin box or possibly get a gooseneck to fifth wheel rail kit adapter but I'd need to know what gooseneck hitch you have.

  • Troubleshooting Chucking with Rota Flex Pin Box and Fifth Wheel Gooseneck Adapter
    Chucking and bucking is not typically the fault of the pin box and is more commonly associated with the fifth wheel hitch or adapter used. We have spoken with Lippert before about the Rota Flex pin box and hitch adapters and they do not recommend the use of these two together. This is due to the forward and rearward movement in this pin box. You should go to a standard fifth wheel hitch and you'll have a much safer and smoother ride quality. What length of bed and gooseneck hitch do...

  • 5th Wheel To Gooseneck Adapter That Will Not Void the Warranty on a Weekend Warrior 5th Wheel
    I do have an option for you but as you have read, a gooseneck to 5th wheel adapter like the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter part # CAB-C5G can void your frame warranty. I would not be able to provide details of your frame's warranty period but I am sure the manufacturer of your frame would which is most likely Lippert. For an option that will not void the frame warranty you can use the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter part # RP94720...

  • Will Using Convert-A-Ball 5th-Wheel-to-Gooseneck Adapter Void Trailer Warranty
    Using the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter # CAB-C5G does void the manufacturer's warranty on some 5th wheel trailers because of the added stress that it puts onto the frame. To determine if this is the case for you though you will just want to contact your trailer's manufacturer. For a trailer mounted adapter that doesn't have this same issue I recommend taking a look at a Reese Goose Box like the 20K # RP94720. These are designed to actually replace the existing...

  • Does Offset Gooseneck Hitch Affect Having Hitch Centered Above Rear Axle
    When you use an offset the weight of the trailer is still placed in the truck bed where the hitch ball is. The offset does not move the weight back relative to the truck bed since the attachment point stays in the same area. If the trailer has a wide nose and you have a short bed truck typically a gooseneck offset won't allow you to make tight turns. That's the downside to gooseneck towing is there's not much you can do for short bed truck clearance unless the nose of the trailer is tapered. If...
