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.

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.

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.
