Trailer is sitting a little bit higher in the front then the old Ram and will have to leave the tailgate open about 6 inches when it slides back but appears to have great clearance for tight uneven corners.



by:

Just what I needed for my truck with the 6’bed. It doesn’t happen very frequently that I need to turn sharp, but if I do, this will make it easier and safer.



by:

Great shipping experience!
Great communication
from etrailer and the trucking company.
Fit right in my 2018 Ram OEM puck
System with ease.

Bought this B&W Companion slider to fit into my 2017 RAM 3500 short bed. I thought very highly of the B&W Companion 5th wheel that was in my F-350 long bed for many years, and decided to stick with a proven product. This hitch is built to the same high quality standards I've experienced with the B&W product line. Very robust (which translates to very heavy) and extremely simple to set up and install in the truck. It is definitely a two person operation to get the base lifted into the back of the truck, but once it up there, it's a snap to get locked down for towing.
The only caution I will offer is that when the slider is in the rearward position, be VERY careful of terrain and grade changes when moving a 5th wheel. It is very easy to damage the top of your tailgate with the trailer pin box. Other than that, it is a supremely well built product that will last a lifetime if properly maintained.

Lastly, the customer service and support at etrailer was outstanding! They helped me located some hardware through B&W that was not included in the packaging (which was my fault for not reading the description). Highly recommend these guys too!

Youll want to be careful with the hitch slid rearward, as this can place the trailer pin weight behind the rear axle, which will diminish the tow vehicles steering and braking performance. The hitch should only be slid rearward during low speed maneuvering.

Great product



by:

We bought this to fit our fifth wheel hitch to the new truck. Fits great. Easy for two (or more) people to take in and out and keep the whole bed usable. Like the original this thing is built like a tank. I have only used B+W but we have well over 10,000 miles on them with no real problems. I will now confess something to y'all: I don't slide it anymore! I got tired of getting out and sliding when I needed the turning range. So I have for the last 1,000 miles or so been leaving it back all the time. My truck weighs 9100 pounds empty and the trailer is only 14,000ish so the difference forward or back isn't really noticeable!



by:

Etrailer had fast shipping and right product! Buy the B&W hitch and never look back! Built like a brick house which instills confidence this product will never let you down and never let go of your cargo. Do it!



by:

Bought the Base only because my new Ram uses the OEM mounts instead of the Turnoverball style mount. This weighs more than the original Companion, but mated right up to my original Hitch Head perfectly.



by:

The installation instructions allowed for easy installation. I've had this B&W slider base for 20K miles on a TurnoverBall mount, and I loved it. I got a new truck with OEM pucs, so I wanted to use them. The fifth wheel hitchh moved right over to the new base.



by:

Awesome Hitch, easy purchase, shipping on time!! This is my second purchase and could not be more satisfied with the ease, quality of products and the communication right up to expected delivery time. Highly recommend etrailer



by:

Nice setup. Fit and function was excellent and quality of build impressive

  • Will a B&W Companion Slider Work w/ a Round Gooseneck Hitch?
    No, David I am sorry there is not. It sounds like you're describing a standard gooseneck hitch. The B&W Companion Slider item # BWRVK3400-5W can only be used with the Turnoverball system or have the base swapped out to fit in the factory puck systems with item # BWRVB3670. This base fits the Ram OEM puck system that has four mounting holes in the truck bed. The only solution I would potentially have is going to depend on what kind of gooseneck hitch your Ram truck has. If you could get...

  • Converting the B&W Companion 5th Wheel Trailer Hitch to Fit a 2017 Ram 3500 with Factory Puck System
    It sounds like you have the B&W Companion fifth wheel hitch, part # BWRVK3500, that fits into the B&W Turnoverball gooseneck hitch. There isn't an adapter to make the square gooseneck shank fit into the round factory gooseneck hole on your new 2017 Ram 3500 but we do have something that'll work for you. Instead you can keep the head of your current hitch and replace the base with either part # BWRVB3600 for the fixed legs or part # BWRVB3670 for the slider. The bases fit into the factory...

  • Replacement B&W Companion Hitch Base for a 2018 Ram 3500 with Factory Prep Package
    We do have some different options when it comes to a base for the B&W Companion 5th wheel hitch that is compatible with your 2018 Ram 3500. If you have a 6-1/2' bed you will want to go with the slider base so that you can avoid trailer-to-cab damage when making tight turns. That is listed as part # BWRVB3670 on our site. For an 8' bed you will just need a stationary base which can be found as part # BWRVB3600 on our site. You can order one of the used stationary bases that is currently...

  • Parts Needed to Install B&W Companion Hitch in 2017 Ram 3500 with Hitch Prep Package
    You can take the head off of our B and W Companion hitch and install it on a base that's designed to fit the factory Ram rail kit of your 2017 Ram 3500. For that we have the part # BWRVB3600 for a fixed base which is what you'd need if you had a long bed truck. Or we have the part # BWRVB3670 which is a slider base. This is what you'd need if you have a short bed truck. Slider hitches are needed for short bed trucks so that you can make tight turns without cab interference.

  • Is there a Replacement Base for the B&W Companion the Fits the Ram OEM Puck System?
    Yes, there is and congrats on the new truck! The head on your B&W Companion item # BWRVK3500 or item # BWRVK3400 if you have the slider is removable from the gooseneck adapter base. Depending on the length of your bed and whether or not you need a slider, there are two options for a replaceable base that works with the Ram puck system and I have listed them below: Sliding Ram OEM Puck System Base - item # BWRVB3670 Fixed Ram OEM Puck System Base - item # BWRVB3600

    Hey Dave. There's no adapter to move puck system compatible hitches over to different manufacturers but you can swap out the base on your B&W Companion OEM 5th Wheel Hitch w/ Slider item # BWRVK3775.

  • B&W Companion Base For 2024 Ram 2500 With Factory Puck System
    Hello Don, thanks for getting in touch. Is your 18K slider hitch a B&W Companion slider? If so, yes, the head unit will fit any other Companion base. So, you can get a new base for your new truck, and save some money by using your old head unit. Is your new truck a 2024 Ram 3500 with the puck system? If yes, use the # BWRVB3670 slider base if you have a short bed, or use the # BWRVB3600 for if you have a long bed.

  • B&W Companion Slider Base For A 2020 Ram
    Hello Lewis. The correct B5W Companion Slider Base for the 2020 Ram is part # BWRVB3670. This is made specifically to fit the OEM puck system on the Ram truck. All of the B&W Companion hitches use the same head unit, so you can indeed use the head unit from your old hitch.

  • Do You Carry Replacement Parts For The B&W Companion Base # BWRVB3670?
    Unfortunately David, we only carry the Base # BWRVB3670 as an assembly. You would have to get the cam latch parts separately from B&W directly.

  • Solution for Needing to Install B and W Patriot Slider Hitch in Bed of 2025 Ram with Pucks
    Hey Leslie, I wish I had the solution you are looking for but there isn't a slider base that the head of your B and W Patriot slider hitch can fit on nor is there an adapter that will allow your Patriot to fit your pucks so your best option is a new slider fifth wheel hitch like the Companion Slider part # BWRVK3670. The only moderate silver lining is that you would be able to sell you old hitch complete which would be easier than just the base.

  • Will The BWRVB3370 Slider Base Work In A Ram Truck?
    Thanks for reaching out, Nick. The # BWRVB3370 slider base is made for the Ford OEM prep package. This will not work in your 2023 Ram since the Ram prep package uses different puck spacing. The good news is that you can purchase a new base for your ram truck, and you can re-use the head unit from your old hitch. All of the B&W companion hitches use the same head unit so they are interchangeable. So, as long as your Ram truck has the OEM puck system in the bed, you can use the slider base...

  • Can Companion Hitch be Installed on Slider Base that Fits 2022 Chevy Silverado OEM Pucks
    Hey Guy, yes you can replace the base of your current Companion hitch with the slider base part # BWRVB3775 and you'd have a slider hitch that fits the OEM pucks of your 2022 Chevy Silverado 2500 short bed. Something else you might consider is that your old hitch would be easier to sell as a complete unit instead of just the base in case you wanted to have less clutter in your garage and also offset the cost of the new hitch. For that you'd need the part # BWRVK3775 for a complete new hitch.

    Hi Mike, Yes, the head of the B&W Companion OEM 5th Wheel Hitch w/ Slider # BWRVK3770 would be compatible with the Replacement Base for B&W Companion OEM # BWRVB3600. If the new Ram has a short bed and you need to stitch with a slider then you can swap out the base with part # BWRVB3670 instead.

    Yes, if you have the factory puck system in both vehicles you would be able to use the B&W Companion OEM 5th Wheel Hitch for Ram Towing Prep Package # BWRVK3600 in the bed of both trucks. Factory Prep Package and Puck System are just two terms for the same thing, 4 "pucks" (mounting points) for a 5th wheel hitch and typically also a puck for the a gooseneck ball.
