Features to know about
Clears the Truck Bed for Everyday Use: Converts 5th Wheel to Gooseneck
If you’re tired of giving up your truck bed to a bulky fifth wheel hitch, this adapter makes it easy to switch. The Ranch Hitch Universal 5th-Wheel-to-Gooseneck Coupler Adapter converts your trailer’s king pin to a gooseneck coupler, letting you tow with a standard 2-5/16" gooseneck ball. Once unhooked, your bed is completely clear for hauling whatever else the day calls for.
Built for Heavy Loads: 24,000 lbs GTW and 6,000 lbs TW
Strength matters when you’re towing serious weight. This heavy-duty adapter is rated for 24,000 lbs gross towing weight and 6,000 lbs tongue weight, certified to V-19 performance standards. With that kind of muscle, it’s ready for work trailers or large fifth wheels and keeps the connection solid mile after mile.
Adjusts to Fit Your Setup: 3" Vertical Adjustment Range
Not every tow setup sits the same, and this adapter gives you the flexibility to match your trailer and truck height. It adjusts vertically from 11-3/4" when collapsed to 14-3/4" when extended, giving you up to 3" of adjustment. That helps keep your trailer level and maintains the recommended 5"–6" clearance between the trailer overhang and truck bed rails for safe operation.
Simple to Use from the Ground: Remote Coupler Release
No more climbing into the bed to latch or unlatch. The remote coupler release lets you engage or release the coupler while standing beside the truck. It’s a small feature that makes a big difference every time you hook up or unhook—especially when you’re on your own.
DIY Friendly Installation: Bolts Over the King Pin
This kit includes all hardware for bolt-on installation, designed so most can install it in under an hour with basic tools. It attaches over the king pin with a threaded collar system and secures with four Grade 8 bolts tightened to 55 ft-lbs. If welding is preferred, four one-inch tack welds by a certified welder can be used instead. Either way, the setup is strong, secure, and ready to tow.

The Ranch Hitch adaptor was a breeze to install. We installed it on our 5th wheel trailer so it would attach to the stock turn over ball hitch in the bed of our F-250. Drove 1,100 miles in 2 and a 1/2 days, from Peyton CO. to Big Bear CA. No problems.

Works great! Used the Anderson Ultimate in the past and it worked great until I put a fuel tank in the truck. After that there wasn’t enough room for the Anderson, needed something different. Check spacing on several hitches but none allowed the room. The gooseneck adapter works as advertised and now have extra bed space for gear. Picked up the gooseneck safety chains also from another vendor just to add the extra safety margin in there. Adapter is easy to hook up and works great. Still have to climb in the bed to hook up safety chains but it does work. Also love the plastic pad between the ball and the hitch so I don’t have a greasy gooseneck ball to deal with.

installation instructions provided by Anderson Manuf are very clear/easy to follow. Hitch is very easy to install. Attached to 30' fifth wheel, 11,000lbs tow weight and immediately pulled the trailer thru steep hill country without any hesitation. Pulling cattle trailers/heavy hay trailers, i know heavy duty hitches when i see them and this is a great product; HIGHLY recommended. Remote latching mechanism is a great feature; it too is very solid/secure

The Ranch HItch 5th wheel adapter AM3100 was everything that we needed and more!! It fit perfectly and was a breeze to install. We will be pulling our "home" around the country when we retire. We didn't want to have the back of the truck to be full of "hitch" with no room for much else. The Gooseneck adapter is the perfect choice for us!! GREAT PRODUCT!!!

I have an Ultra-Fab trailair air ride kingpin system on my fifth wheel. Can the gooseneck adapter be installed on that type of system?
Patrick B.
8/19/2013
According to Ultra-Fab, the Trailair pin boxes are not to be used with any kind of gooseneck adapter where the pin box is adapted to attach to a gooseneck ball. You can however adapt the truck to accept a 5th wheel hitch. Your best bet would be a fifth wheel hitch that anchors into a gooseneck like the Demco Recon, part DM8550045 or a Curt Fifth Wheel Adapter plate like C16210 or 16310.

I have pulled my camping trailer approx. 300 hundred miles since I installed the adapter. It works great. Installation was pretty simple, the only difficult part was drilling the four holes thru my fifth wheel box. E-trailer service and shipping were great!

Installed on my fifth wheel. Easy to follow instructions, total time was about an hour. The lock is easy to place, install and use.
Be advised: if your king pin box is enclosed, you will need to weld this product on.

High quality, heavy duty. I was hoping this was a more temporary mount if I decided to utilize the 5th wheel king pin. However, this is threaded on with 400lb torque and I had to tack weld the mount to the bottom of the king plate as there was no access to bolt through the pin box.

Seems to be a very well built product. Good price and shipped fast. Fairly simple to install, I recommend having a friend or two around to help tighten everything down. Also I preferred to bolt rather than weld ( unless you have a closed off pin box), you never know when you may need to go back to fifth wheel in a hurry.

How does collar system attach to king pin ? Thanks
Patrick B.
11/26/2013
There is a threaded collar that is fitted to the king pin. You would slide the coller up on the king pin. While holding the collar, you will take a split collet and fit that where the jaws normally grab the king pin. You will slide the threaded collar over the split collet and using either a pulley puller or Andersens hammer to seat the collar fully onto the split collet. I have added a pictorial of this portion of the instructions to the photo gallery and linked it here as well. The base of the adapter threads onto the collar and is tightened to ~1200 ft. lbs. The process for getting that much torque is outlined in the instructions and uses the included spanner wrench and a 4 foot cheater pipe. Finally, you will use either the inlcuded four Grade 8 bolts or four 1 inch tack welds to finish securing the adapter to the pin box. If you want to be able to remove adapter, make sure you can access the inside of the pin box so you can use the bolts vs. welds.

Order confirmation was fast, shipping was fast, they said it would be here Saturday but ups doesn’t deliver on Saturday or Sunday so it didn’t get here until Monday. I knew this so I was expecting it and I didn’t need it right away so to me it didn’t matter. Everything was delivered in good shape when it got here. I’ve bought one of these from strainer before and liked it so when I found I was in need of a goose neck adapter again I got the same one and etrailer came through again. This adapter is expensive but it works great. Would recommend.

The hitch was shipped the same day it was ordered. It arrived in five days in excellent condition and with no parts missing. It took me longer to install it because I had to remove the king pin box component to drill the bolt holes and mount the bolts to provide the additional support I wanted. An excellent product and a good price.

- Recommended 5th-Wheel-to-Gooseneck Adapter for 2018 Ram 3500The reason the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter # CAB-C5G is not recommended for use with factory-installed gooseneck prep packages on Fords from 2011-present and Ram from 2013-present is because they use a gooseneck ball that has a plastic handle on top (see photo) that folds into the hitch ball and the Convert-A-Ball # CAB-C5G has a nut on the inside that will damage the gooseneck ball.

- Will My B&W Companion Hitch Work In My New Chevy 3500?That completely depends on what style of Companion hitch you have. If your Companion hitch was made for the 2020-2024 GMC/Chevy puck system such as the # BWRVK3710, you can easily transfer it to the new Chevy 3500, provided the truck has the OEM fifth wheel puck system (not just the gooseneck).

It is possible to connect this pin box to a gooseneck hitch using an adapter like the Ranch Hitch Universal 5th-Wheel-to-Gooseneck Coupler Adapter # AM3100.

This will help absorb road shock and improve the stability of your truck.

If you have a different Andersen Gooseneck Coupler it will work fine just as long as it requires a 2 5/16" ball.

That is great to hear and a heck of a road trip! What kind of 5th wheel did you install it on?
