Switching from a bulky fifth wheel hitch to haul cargo often requires removing heavy hardware from your bed. This pin box converts your trailer to a gooseneck, reducing in-bed equipment while adding dual-axis cushioning for smoother towing.


Highlights

  • Open Bed Between Trips: Gooseneck connection removes bulky in-bed hitch hardware from cargo runs.
  • Controlled Towing Motion: Dual-axis cushioning absorbs up-and-down and front-to-back movement.
  • Road Shock Dampening: SumoSprings suspension manages road shock across rough pavement.
  • Ball Hookup Alignment: Large funnel design gives the coupler a broad target at the gooseneck ball.
  • One-Pull Coupler Release: Easy-reach latch cable releases the coupler from an accessible position.
  • Immediate Towing Setup: Maintenance-free spring system needs no break-in period before towing.

Features to know about

Open Bed Space Between Towing Trips

B&W 5th Wheel to Gooseneck Pin Box on Truck

A large fifth wheel hitch takes up valuable space in your truck bed. This pin box converts compatible fifth wheel trailers to a gooseneck connection, replacing the bulky in-bed hitch with a ball connection and freeing up bed space for hauling cargo between trips.

Reduced Bouncing and Road Shock

B&W 5th Wheel to Gooseneck Pin Box Cushions

Rough roads can cause your trailer to bounce up and down or move forward and back, sending jolts through the hitch. The dual-axis cushioning absorbs movement in both directions, with SumoSprings helping dampen road shock for a smoother towing experience.

Gooseneck Ball Hookup Control

B&W 5th Wheel to Gooseneck Pin Box on Truck

Hooking up a gooseneck takes careful positioning when the coupler target is small. Large funnel design gives the coupler a wider lead-in area as your trailer settles onto the ball. Coupling lines up with a broader target, and the easy-reach latch cable releases the coupler from an accessible position.

I installed the BW 73RV pin box and I am impressed. It is a very sturdy unit and was easy to install and adjust. I like that the chains have safety hooks on both ends so you can hook to the truck first and don't have to crawl in the bed to hook up chains after connecting the fifth wheel. I did have to buy a good padlock to secure the hitch since a standard gooseneck lock will not fit. It would be nice if B&W made a good theft deterrent lock for this pinbox. I have only driven a short distance with the hitch but it seems very smooth. We have a trip coming up and I'm excited to see how it does

B&W makes some great products. Where do you plan on taking the trailer now that you are all set up?

We are going to head toward The Moryde facility in Elkhart Indiana to have the independent suspension with hydraulic disc brakes installed on August 3rd. We are making a cross country trip out of it we are going to Theador Roosevelt National park, Two Harbors Michigan, the ark encounter in Kentucky, visiting family in Tennessee, then headed down to New Orleans, that making our way back to Idaho through Albuquerque New Mexico and Durango Colorado.

@Russell Oh wow, that is awesome. Disc brakes is one of the best upgrades out there for stopping power. You have quite the trip planned, New Orleans is my FAVORITE. Are you visiting Lafitte's Blacksmith Shop?

Overall, during normal driving conditions this hitch is fantastic. Super smooth, and really easy to hook up and disconnect. However, watch out when you hit bridge transitions, expansion joints, or bumps because this thing BUCKS like crazy. My actual pin weight of my trailer is right around 3k lbs so I'm within spec. However I think since I'm near the upper end, the springs compress more.
by:
I waited for a couple weeks to get a good perspective with the new hitch. After driving I 40 through New Mexico and several states I can honestly say this is my best hitch in 22 years of experience towing. Some chucking still happens but diminish by at least 75%.

Product is great but was not expecting a semi truck for delivery. Only had an hour notice that this massive truck was how it was coming. Luckily my wife was able to meet the driver in the street with our truck or it was going to be returned to the shipper.

See what our Experts say about this B and W 5th Wheel Gooseneck Adapter

  • Which B&W Fifth Wheel to Gooseneck Adapter Is Best For Towing My Trailer?
    Hi Glen, It will depend on what the GVWR (gross vehicle weight rating) is of your trailer to determine which B&W 5th wheel to gooseneck adapter will work best for you. Fifth wheels and gooseneck trailers go off of pin weight instead of tongue weight like a bumper pull trailer uses. Pin weight is 15-25% of your trailer's GVWR, typically we use the formula GVWR x 0.22 to give us a median pin weight number. For example, if the weight of a fifth wheel is 18,000lbs GVWR then we do 18,000 x...

  • Will B and W Fifth Wheel to Gooseneck Adapter Void Lippert Frame Warranty
    Hey John, this is a great question. I asked B and W about whether or not the B and W Fifth Wheel to Gooseneck adapter part # BW73RV would void the frame warranty and they said it has been extensively tested and engineered to provide a smooth, stable ride that helps reduce stress on both the truck and trailer. Use of the adapter should not void your trailer's frame warranty. What fifth wheel camper do you have?

  • Will B&W 5th Wheel to Gooseneck Pin Box Fit 2020 Vanleigh Beacon 34RLB
    Hey Justin! Based on the pin weight and GVWR of your 2020 Vanleigh Beacon 34RLB you will want to get the 4.5k TW model. There are two different models depending on your bolt pattern. If you have a Lippert 1621, 1621HD, 0719, or Fabex PB 600 Series you need the B&W 5th Wheel to Gooseneck Pin Box # BW83RV. If you have an 1116 or 1716 you need the # BW83RV with the shim kit # BW57MV. If you have the Lippert Rhino Box on there now you need # BW55RV instead. If you aren't sure which bolt...

  • How to Determine Clearance Using B&W Gooseneck Pin Box With 2009 Ram 3500 Short Bed
    Hey Fred! You will need to take some measurements to determine if you will have enough clearance with the B&W Gooseneck Pin Box # BW23RV. You can use the following formula: (A + B) - C = Clearance A = Distance from the gooseneck ball center to the truck cab B = Offset used C = Width of the nose of the trailer divided by 2 As long as you have at least 4" of clearance you will be able to make a 90 degree turn. You can also live with the lost clearance as long as you know your limitations....

  • Will B&W Gooseneck Pin Box Fit Brinkley Z2900
    Hey Dean! The B&W 5th Wheel to Gooseneck Pin Box # BW73RV will fit your Brinkley Z2900 if you have a Lippert 1621/1621HD bolt pattern. Also yes, there is a heftier model, which is the # BW83RV with a max tongue weight (TW) of 4,500 lbs. What is your pin weight with the generator? As long as you aren't over that 4.5k limit you're good. If you have an 1116/1716 you will need the 1621 pin box along with the Shim Kit for B&W 5th Wheel-to-Gooseneck Pin Box # BW57MV.

  • Does B&W 5th Wheel to Gooseneck Pin Box Include Safety Chains
    Hey Shawn! Yes, the B&W 5th Wheel to Gooseneck Pin Box # BW23RV does include safety chains. That is one of the first things we asked them when they came by to show us the new pin box. They also throw in replacement hardware so you're covered if you need it. Gooseneck pin boxes are already pricey, and it can be easy to forget the safety chains, so it is nice that B&W decided to include them. This particular model is designed to fit a Lippert Rhino bolt pattern so make sure that is what...

  • B&W Gooseneck Pin Box for 2025 Alliance Avenue 32RLS With 2026 Ram 3500 Dually
    Hey Paul! The correct B&W Gooseneck Pin Box depends on your pin box bolt pattern. If your 2025 Alliance Avenue 32RLS has a Rhino Box you need # BW23RV and if it is a 1621/1621HD # BW73RV. If you aren't sure, please send me a picture of your pin box sticker and I will be able to identify it through Lippert. Both of these are the 3.25k TW models which is the proper rating for your Alliance Avenue. Where are you headed once you upgrade the pin box and get your new truck?

  • What B&W 5th Wheel to Gooseneck Pin Box Do I Need For A KZ D326RLT?
    Hey Donald, thanks for reaching out. We will definitely have a gooseneck pin box for you, but they aren't make and model specific, so there is no way to look up the camper and know exactly which one you'll need. Specifically, we need to determine what pin box size/bolt pattern the camper was equipped with from the factory. The dealership might be able to tell you, otherwise, the only way to figure that out is by looking at the pin box and finding the sticker on the side. Every camper will...

Assuming you just want a standard pin box upgrade, the MORryde Cushioned 5th Wheel Pin Box for 14K to 18K Trailers w/ Lippert 1116 # MR87VR you were looking at is a great option.

  • Suspension Upgrades for 2026 Alliance Avenue 35RKS
    Hey Kent! Your Alliance Avenue already has some great suspension components with the MORryde CRE3000 equalizers, wet bolt kit, and Rota-Flex pin box. I wouldn't replace any of those unless you're experiencing a specific problem. The next upgrade I recommend is the MORryde X-Factor Crossmember # MR33WR. This reinforces your spring hangers to reduce side-to-side movement and adds strength to the suspension mounting points. This is especially useful for frequent camping, and helps keep your...

  • Which B&W 5th Wheel to Gooseneck Pin Box For A 2023 Forest River Sabre 37FLL?
    Hi Sonny, cool camper! The B&W 5th Wheel to Gooseneck Pin Box - Lippert 1621/1621HD - 25K GTW - 3.25K TW # BW73RV will be a great choice! With your 2023 Forest River Sabre 37FLL having a 2,600 pound pin weight, this one will be the better option (the # BW83RV has a much higher pin weight capacity of 4,500 pounds and would end up being pretty rough). You can also use a 4" offset ball with these as well. That's no problem at all. If you don't already have one of those, I will need to know...

  • Which B and W Fifth Wheel to Gooseneck Adapter for 2025 KZ Durango Gold 358RPQ
    Hey Russel, so fifth wheel pin weight is generally between 15 and 25 percent of the total weight of the trailer as it sits ready to tow. This is different than the GVWR that you mentioned as that number is the total amount the trailer can weigh at max. So most likely the part # BW73RV would be your best option as if you use 20 percent of the GVWR you end up at 3,000 lbs which is under max rating of the # BW73RV plus fact you are most likely not going to be at the very max your trailer can...

  • How Much Does The B&W 5th Wheel to Gooseneck Pin Box BW73RV Weigh?
    Hi David! The B&W 5th Wheel to Gooseneck Pin Box - Lippert 1621/1621HD - 25K GTW - 3.25K TW # BW73RV weighs right at 175 pounds. It's beefy, but it's also very nice. As all B&W stuff is. This can be installed at home, but it's not easy and you will either need a forklift or a couple friends to hold it up while you put the bolts in place. What are you wanting to install this on?
