Backing or turning with a short-bed truck can get tight fast. The built-in slider on this hitch gives you 12" of fore and aft travel, letting the trailer move back toward the tailgate at slow speeds so you have the clearance you need between the cab and the front of the trailer. It’s a simple mechanical slide built into the base, and once you’ve used it, you’ll wonder how anyone tows a fifth wheel without one.
This setup is rated for 20,000 lbs gross towing weight and 5,000 lbs vertical load, so it’s ready for large fifth-wheel campers and long hauls. The 1" thick dual jaws wrap completely around the king pin for full 360-degree contact, giving a quiet, solid connection that feels locked-in mile after mile. The gray powder coated steel resists corrosion, keeping the hitch looking clean even after seasons of use.
The cam-action latching handle helps prevent binding, so releasing or latching stays smooth even on uneven ground. The fully articulating head pivots front-to-back and side-to-side to match the trailer’s movement, which helps limit chucking and makes hook-ups more forgiving. Polyurethane bushings cushion the head movement for a quieter, rattle-free ride.
When you’re done towing, this system breaks down into two pieces for easier lifting and removal. The hitch connects directly into the included Turnoverball gooseneck hitch using a single ball hole in the bed. Pull it out, flip the ball over to stow it upside down, and your bed is wide open again—no rails left behind. It’s a true rail-free setup that installs using existing frame holes without any welding.
Dial in your fifth-wheel height with three settings between 17" and 19". The pivot arms let you tweak both height and fore/aft placement so your trailer sits level and clears your bed rails properly. Once adjusted, the solid pin connections keep everything tight and secure for consistent towing each time you hitch up.
This fifth-wheel trailer hitch is not compatible with Sidewinder or Revolution king pins. Do not use any device that changes the pivot point of your trailer's king pin with this hitch.

Today we're going to review part number BWGNRC959. This is the B & W Turnoverball Underbed Gooseneck Trailer Hitch with a thirty thousand pound weight capacity. This heavy duty underbed hitch will let you tow your gooseneck trailer. When you turn the ball over it'll give you complete truck bed access when you're not towing. Basically what you can do is pull the handle, lock it open, pull the ball out, flip it over, drop it back into place, and then release the handle and the pin will lock it into place. With it flipped upside down then you'll have the full truck bed access.
It does have a five-eighths inch diameter spring loaded steel locking pin on the end of this handle which will go all the way through the ball to secure it into place. Right now, with it released, the pin goes through it. It's locked into place. When you want to remove it just pull out, lock it open. You can see the hole where it slides through.
It doesn't matter which side you put it in. When you're ready to tow, drop this, again, release the pin, and that pin will go all the way across and hold it into place. Very secure. This access handle right here will be at your rear driver's side wheel well to access it. The ball itself is a single piece machined ball socket. Pull it out so you can see here.
It provides rugged durability, has a square ball base that prevents the ball from turning in the hitch during hook up, and if you look at the corners they sort of beveled them off. This is a corners only fit so when you drop it in the stow position it prevents any grime from building up in the corners inside of the hitch. Now we do offer some special specifically designed accessories. We sell them separately on our website, usually listed as related products, that make it easy to customize this hitch to fit your needs. You can also get ...
We offer a B & W companion hitch adapter. What that does, it will drop, it has a post on it. It's a fifth wheel hitch. It can drop in to there and lock into place and you'll be able to also tow a fifth wheel. They also make a ladder rack by B & W that you can also . It has a post on it that drops in there. This ladder rack will leave your truck bed side rails free and you can still carry ladders on it. This gooseneck hitch, you can see it has the spring loaded safety chain hook ups, which are built in. When you go to attach your safety chain just pull up, hook it in, and it holds it into place. This is a very simple installation. To install this it does require a custom installation kit. We do sell those separately. They are vehicle specific. What you need to do is go on our website, go to our fit guide, type in the year and model vehicle, and then it'll show you what installation kit you need for this gooseneck to install on your vehicle. The only thing is on your truck bed you would need to cut a four inch diameter hole so this would come through and you'd have access to the opening. The finish on this is a powder coated steel which is very sturdy and corrosion resistant. This part is made in the USA. A few specs on it, again, the gross towing weight capacity is thirty thousand pounds. The tongue weight or pin weight capacity is seventy-five hundred pounds. The ball size is an industry standard two and five-sixteenths gooseneck ball. It does come with a limited lifetime warranty. Again, just to show you, if you're ready to tow with it you just drop the ball into the opening, release the pin, and it will lock it right into place. When you're wanting to stow the ball you just pull it, twist it, and you'll see on top there's a slot that'll open and then a cutout, and it shows you where you can just lock it open, pull up on the ball, there's a little handle here you can hold on to, turn it over, drop it down, release that pin, and it's locked into the stowed position, you have the full truck bed access then. That should do it for the review on part number BWGNRC959. This is the B & W Turnoverball Underbed Gooseneck Trailer Hitch with the thirty thousand pound weight capacity. .

It is still the best 5th wheel hitch that Ive owned. Very minor maintenance required. Just a little white lithium grease on the swivel points and a Teflon plate instead of grease.

Every thing has been working good. Seems to take a good jolt to get it to slide with the trailer attached. Still a great product

Youll want to make sure that the slider rails are lubricated. Also keep in mind that if the truck and trailer are at different angles and theres a lot of pressure placed on the sliding mechanism, it can bind.

A year later, and it still works the same. Slider still doesnt work. but havent needed it. One thing I have learned is to make sure the lug from the attachment is lubricated before placed into the receiver. After about 8 months of being in the bed, I tried to remove it. Whoah! That was a son of a gun. Finally got it to break free, and then it lifted out. both the lug of the companion hitch, and the receiver of the B&W are nicely powder coated. that powder coating locked together. Nothing patience and a pry bar couldnt fix. But I dont want a repeat. Over all, I may look at something easier for our next travel season.

Still works great. Have taken quite a few trips around my state and a nice trip to the beach. This hitch has allowed me to get into places that I shouldn’t and get out of those place I dang sure shouldn’t have tried to fit.
