Absolutely love this hitch! It works great!



by:

Heavy, Heavy, Heavy!!
I know this has
to be solid to do the job it needs to do but wow 225lbs
4 stars is for the person that wanted to send me a base for a GM puck system because the Ford base was out of stock.



by:

I like that this slider base is compatible with the head unit from the non slider base I have. It came very packaged with no damage. Installation was very simple. I had the misfortune of having to do a jackknife turn with my 5th wheel trailer, resulting in a smashed rear window on my truck, should have known better. This slider base will eliminate that from happening again.

This is working great, I don’t have to use it all the time but it’s great peace of mind when you need it.



by:

Easy install and works exactly as advertised. Also arrived on time as stated on invoice.



by:

The B&W Companion slider hitch is a a quality American made product that performs as advertised. I have always used B&W products and they never fail to disappoint, they just work!!

I bought a Ford F-250 with the 6 1/2 ft bed and was concerned about cab to fifth wheel clearance issues. I seldom have neededthe slider but it’s nice to know it’s there if I do. There is no play and the sliding mechanism locks up easily and very solidly.

I am very happy with this product!

Great



by:

I purchased a new F350 and already had a companion fifth wheel slide hitch for a B&W goose neck style connection. The new truck had factory installed four point 5th wheel hitch option installed. I was able to purchase the base and reuse my coupler for the king pin, saving over $500. Installation was easy and only took 30 minutes. I have been very impressed with the quality of the hitch and the added bonus is it's entirely US made. I can't wait to take my new setup on the road!



by:

The B&W hitch is great. The service from etrailer was not up to expectations. “In stock” should mean all parts of the order are in stock. I received box 1 of 2 and had to call to point out that only half the order was sent. All in all, it took 3 weeks to receive my complete order, not the 4 days that was outlined during the transaction.



by:

I actually have not used the product yet but have installed it in my my vehicle. Will be using it in February and March 2019 on a trip that was scheduled for this year and had to be canceled. I can say at this time I am very satisfied at the easy installation of this product and will be very satisfied if it performs as well as the installation worked.



by:

I think my B & W hitch is great and wouldn't want any other kind.



by:

Great Base, it is heavy but anything well built is. I wanted a hitch that will last. Had to purchase the OEM Ford base to fit my reese elite that was on my 3500 Chevy silverado.



by:

Installed in minutes. Works great after hook-up with fifth wheel.



by:

Great product and customer service! Shipped and arrived quickly. Very happy!



by:

We have busted out 2 rear windows in the truck. We are hoping this will end that!!!



by:

Always a great experience



by:

It is heavy to put in and out, so that being said it is robust and works great.



by:

Product is excellent. Very durable and well made. Would recommend this product to anybody. Very happy!!!



by:

Super fast delivery, and everything was packaged perfectly. I would certainly buy from them again.

  • B and W Companion Slider Recommendation for 2016 GMC Sierra 2500HD With Ford Elite Rail Kit
    If you have the Reese Elite underbed rail kit part # RP30868 installed in your 2016 GMC Sierra the correct slider B and W Companion is the part # BWRVB3370. This is the kit designed for Ford factory rail kits which are the exact same as the Reese Elite rail kits. The GM rail kit dimensions are much different. For the whole hitch assembly that includes the slider and the head you'd want the part # BWRVK3370.

  • Rails for B&W Hitch on 2023 Ford F-250 With Aftermarket Puck System
    Hello Jeff, With having an aftermarket pucks system I am assuming you went with the Reese, I know that one mirrors the factory one from Ford. If that is case, then you have some options. For rails you want # C88KR, they are Curt rails but they use the industry standard so your B&W hitch will sit on them no problem, unless you have the B&W Patriot Slider, it will not work. Also by using these rails it will add 2 1/2" to the height of your B&W hitch. Or you can change out the base of...

  • Will The B&W Companion Fit Ford F350 Factory Pucks?
    Hi James! The B&W Companion can definitely fit a Ford F350, but not to the factory gooseneck ball hole. The reason for that is the post on a Companion hitch is square whereas the posts on factory gooseneck balls are round. A round hole would allow the Companion hitch to twist, and that would be very bad. All the bases will fit into the 4 pucks in your bed though. You didn't mention the year, though Ford has never changed the pucks so this doesn't really matter, or bed size so I have a...

  • Is There An Adapter For BWRVB3370 Ford Hitch To Go To 2024 GMC Factory Puck System?
    Hello David. There is not any kind of adapter for the # BWRVB3370 Ford hitch to go into a GMC Puck system. You would have to get a whole new slider base that is intended for the GMC puck system. Why do you ask? Do you already have the BWRVB3370 hitch and you just got a new GMC truck?

  • What is the Difference Between the BWRVK3370 and the BWRVB3370
    The B&W Companion Hitch # BWRVK3370 is a complete sliding hitch that is designed to fit in the Ford OEM prep package. The Replacement Slider Base for B&W OEM 5th Wheel Trailer Hitch - Ford Towing Prep Package - 20K # BWRVB3370 is just the base of the hitch without the head and is used if you already have a Companion hitch and have switched from maybe a Chevy truck with the prep package to a Ford with the OEM prep package; it's just designed so that you don't have to buy a completely new...

  • Can I Transfer Old B&W Companion Hitch to New Ford Super Duty with Factory Tow Prep Package
    I do have a solution for you but there isn't an adapter or a pin that can be used to connect your B&W Companion 5th wheel hitch through the Gooseneck hole on your new Ford Super Duty truck with factory-installed towing prep package. The only solution is to use the fixed Replacement Base # BWRVB3300 with your existing B&W Companion head if you have a long bed or the Replacement Slider Base # BWRVB3370 if you have a short bed. Either one will drop in directly into the four pucks on a 2011...

  • Will B&W Companion Slider Base For Ford Fuper Duty Puck System Fit B&W Companion Head For Chevy
    Yes you can do exactly that; the B&W Companion uses the same # BWRVC3006 head unit on both hitches, and since you already have that head unit from the Companion hitch on your Chevy, you can simply purchase the Companion sliding base that fits your Ford Super Duty with the puck system. So what you need is the following: - Replacement Slider Base for B&W OEM 5th Wheel Trailer Hitch - Ford Towing Prep Package # BWRVB3370

  • B&W Companion Replacement Base for Ford Prep Package
    I have a solution for you but you are going to need to replace the base of your B&W Companion 5th Wheel Hitch so it can fit in the OEM towing package on your new 2022 Ford F-350 Super Duty. The square shaft you are referring to only fits in B&W's turnover ball system and you can not adapt it. If you have a slider you will need the Replacement Slider Base for B&W OEM 5th Wheel Trailer Hitch - Ford Towing Prep Package - 20K item # BWRVB3370. If you have the 20k Companion you will want...

  • Can The B&W Companion Fit Into A Ford OEM Puck System Gooseneck Hitch
    The B&W # BWRVB3405 is not compatible with Ford's OEM puck system, which has a standard round gooseneck hitch. You would need to swap the base to part # BWRVB3370 in order to fit the hitch inside the pucks instead.

  • Replacement Companion Bases for the Ford OEM Puck System
    There is a way to reuse the head of your current B&W Companion Hitch but you will need to replace the base with either the fixed Replacement Base item # BWRVB3300 or the Replacement Slider Base item # BWRVB3370. Both of these bases fit in the Ford factory puck system. There isn't an adapter that will allow you to use your Companion hitch in its current form in the Ford puck system. Another option is to sell your current Companion hitch and purchase one of the ones listed below that fit...

    The B&W Companion hitch like # BWRVK3500 is not compatible with the round gooseneck in any of the factory underbed systems. The square adapter give the hitch stability and support preventing left to right movement of the hitch that a round hole obviously won't be able to do. If you already have the Companion hitch, then you can use the hitch head and simply get the factory prep compatible base. For the fixed hitch base # BWRVB3300 and for the sliding hitch base # BWRVB3370. If you...

    I have a solution for you but the Reese Elite Series Under-Bed Gooseneck Complete Hitch, Item # RP30158-68 uses the same pattern as the Ford factory puck system. The correct B&W hitch will be the B&W Companion item # BWRVK3300 for a fixed hitch and a long bed or item # BWRVK3370 for a slider hitch if you have a short bed and need the extra turning clearance. If you already have the head and just need to replace the base you will want the item # BWRVB3300 for the fixed base and item # BWRVB3370...

  • Can B&W Companion Slider For Ford F-250 Prep Package Tow in Slide Position
    It cannot; here is what B&W states regarding using the Companion in the slide position (which they call the "maneuvering" position): "The maneuvering position is only intended for parking maneuvers and not for towing. Using the slider in any other capacity could result serious injury or death." This is actually true of all sliding hitches, as none of them can be used in the slide position.

    I do have a few options for you to raise the trailer, assuming it has leaf springs you can either go with an over under kit like the Dexter Trailer Springs Over-Under Conversion Kit part # K71-384-00 for 2-3/8" axles and part # K71-385-00 for 3" axles or a leaf spring hanger extension kit like the Correct Track Trailer Alignment and Lift Kit part # RR23QX.

  • Can B and W Companion Slider Hitch for GM Factory Rail Kit be Used in Ford Rail Kit
    The only option you really have if you wanted to reuse as much of your current hitch as possible would be to swap the head off of your current Companion slider for GM rail kits part # BWRVK3770 onto the base slider that fits the Ford OEM rail kit part # BWRVB3370. It might be a better option though to go with an all new Ford Companion slider hitch part # BWRVK3300 as that would allow you to sell your old hitch as a complete unit which would be easier than just a base.

This will drop right into the puck system for easy installation and removal.

  • Converting B&W Companion 5th Wheel Hitch to Use in Ford Super Duty Prep Package
    Yes, you can convert your standard B&W Companion 5th wheel hitch for use with the Ford Super Duty prep package. The B&W Companion hitches use the same hitch head, so all you will need to do is replace the base, which will allow you to mount the hitch in the Ford pucks and save you some cash so you don't have to buy a whole new hitch. I'm not sure if you need the sliding base or fixed base, so here are both options for you: - Replacement Base for B&W Companion OEM 5th Wheel Trailer Hitch...

  • Dimensions of Replacement B&W Companion Slider Base for Ford Towing Prep Package
    The Replacement Slider Base for B&W OEM 5th Wheel Trailer Hitch # BWRVB3370 has a base that is about 34" long x 36" wide according to my contact at B&W. The difference between the higher weight rating of this and the lower rating of older models really just boils down to the overall construction. This has thicker/more durable materials that can handle the higher rating. If you're also needing the hitch head then you can get the complete setup for a Ford Towing Prep Package as part # BWRVK3370.
