4" Offset Ball for B&W Turnoverball Gooseneck Trailer Hitches - BWGNXA4085

Average Customer Rating:  4.8 out of 5 stars   (289 Customer Reviews)

Designed for use with B&W's Turnoverball gooseneck hitch, this ball extender moves the pivot point of your trailer 4" rearward to provide additional cab clearance.

This product is exactly what I needed to offset our new “Reese Goose-box” pin box to better accommodate the clearance for the fuel tank and tool box in the bed of our truck. Thanks to the knowledge of the “etrailer” staff (specifically Stacy) she went the extra mile, taking additional time to assure all the products I needed were perfect for my application. Thank you Stacy for all your assistance and patience with my order.
P.S. I added the yellow strip down the center of the pin box to help guide me when hooking up. Perhaps “Reese” will add this little idea to their future pin boxes as an option?

This product works great and allows so much more usable room in the bed than our previous 5th wheel hitch which, was becoming too heavy to remove frequently when needing to haul materials.

@Dean We're happy to hear that the # BWGNXA4085 offset gooseneck ball is working well for you.


by:

I can only rate the service from etrailer.com because I haven’t actually used the 4” Offset Ball yet. It arrived as promised and in good shape. It looks exactly like the picture I I have no doubt whatsoever that it will work perfectly for my fifth wheel. Very happy with etrailer.com



by:

This worked perfectly like I wanted it too. I was able to pull our new fifth wheel camper and it won't get into the cab when I turn, thank you Etrailer.



by:

The 4” offset adds better balance at the same time provides adequate clearance between nose of trailer and cab . Thanks



by:

I have used this offset ball in the B&W gooseneck hitch I installed in my regular box 2022 Chevy 3500 to tow our 13K GVWR fifth wheel with Reese Goosebox for over six months now and I love it! The offset ball combined with the placement of the hitch in a 2020+ Chevy means I can turn a full 90 degrees if necessary. And fully loaded, our truck is still within specs on all weight ratings, including rear axle weight.



by:

I have a 8ft bed but when hooking up and working around the truck with camper hooked up it was difficult... with this ball I can open all the front Compartments. Pulling the toyhauler feels better to.. we have the goosebox 20k on the toyhauler.



by:

The 4 inch offset ball is very heavy made. I have no concern hauling a trailer with this.



by:

Works exactly as I need it to. Having a 38 ft, 96" wide goose neck Keystone Cougar trailer and a RAM 2500 with 6'4" bed, I needed offset on my hitch for safety purposes.

I have a few thousand miles of travel using this setup and it works fantastic. I spray on a dry lube before every use but have had most of the protective coating on the ball come off, which is what I expect to happen with heavy use.

I would would buy again, if needed, but I expect years more use out of this BAll.



by:

After installing the Gen Y Executive gooseneck hitch on our 5th wheel camper I needed more clearance in my 2016 GMC 6.5' truck bed. I already have the B&W Turnover hitch on my truck and this gave me 4" offset to the rear of my truck and 2" of lift. After 1 year of using this setup I am very pleased with the ride and towing.



by:

Etrailer is awesome! They always have what I need, great prices, great customer service, great product, just like the gooseneck extension Ijust received. Shipping was amazingly fast too.



by:

High Quality, Heavy duty 4” offset ball mount that works perfectly with the B&W turnover gooseneck hitch system. Adapted my 30’’ fifth wheel trailer with the Ranch regular gooseneck adapter—now no more heavy lifting and lots more room in the truck bed.



by:

Fast shipping... The B&W 4in extension hitch ball is really good. I have used it a couple of times works great wish I had gotten one sooner. Problem I had was in a newer 2500hd the gooseneck was to close to toolbox and really close to rear window. With this extender ball problem is solved...



by:

The test will be when I hook up a trailer. My customer service was fantastic.



by:

Bought it, but have yet to use it… it’s very heavy duty and looks like it will last forever…. Thanks & I look forward to using it…



by:

Wonderful Product!!! Couldn’t be more s atisfied!!!



by:

Love how well this works. There are some offsets that are bigger but this worked well. I have a 5th wheel that has a gooseneck adapter and this gives me in my short bed truck a little bit more turning radius.



by:

Great product, and perfect fit. Gave me the perfect offset that I needed to keep my trailer from hitting the cab. Highly recommend if you have a short wheel base truck and pulling a deck over gooseneck trailer!



by:

I haven’t used it yet, I am concerned about it being about 3/4” off the bed. I am thinking about pupping a spacer between it and the bed. Worried about it bending

Etrailer Expert

Sierra K.

3/17/2021

Thanks for your review. This gap is normal since it fits a few different vehicles. It is safe and should not bend. You can put a washer there for peace of mind, but as long as you do not go over the weight capacity, it is not necessary.



by:

Excellent addition to a short wheel base truck.



by:

This product works great for short bed truck. This product gives you more turning radius with out knocking your back window out.
Truck is a 2500 Ram, pulling 42ft gooseneck.



by:

Great website. Easy to navigate and order prompt shipping



by:

My order was lost in transit and replaced immediately, no questions asked. Thank you!



by:

Great product and what I needed for a mega cab to pull Rv camper with goose box



by:

I have a 2005 F 250 crew cab short box. I changed from a 5th wheel for simplicity and ease of switching from a trailer to a slide in camper. So, this is all I have to remove in order to be able to put the camper on. I am getting older and this is just enough weight to carry around. The offset is perfect to jackknife the trailer. The towing with this set up is way better than the fifth wheel. Way more solid feeling and no clunking. I should have done this years ago.

Jim

Excellent. Like it - Will never go back to a fifth wheel.

BW always excellent quality.

  • Is Removal Of The Bed Necessary To Install B&W Turnover Ball Gooseneck on 02 Ram 2500 or 09 Ram 3500
    Installation of both the B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1394 for your 2002 Ram 2500 and # BWGNRK1308 for your 2009 Ram 3500 Mega Cab short bed will not require the bed to be lifted or disconnected in any way. The instructions for both do mention a lifting device is recommended but this is only for holding the center hitch section under the bed while you bolt it up to the cross rails. I recommend getting a Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring...

    I have a way to attach an offset gooseneck ball to the Ram OEM prep package but the 4" Offset Ball for B&W Gooseneck Hitches item # BWGNXA4085 will only fit in the square receivers for the Turnover Ball Systems. Since your 2018 Ram 2500 has the OEM prep package you will want the Gen-Y Hitch Gooseneck Trailer Hitch for Dodge Ram OEM Puck Systems item # GY83XR. This will give you a 5" offset and a 25,000 lbs capacity 2-5/16" hitch ball. It uses the pucks closest to your cab and the center...

  • Best Offset Option for Fifth Wheel Towing with 2014 Ford F-150 5-1/2 ft Bed
    An offset that doesn't pivot will always give you better cab clearance. The # BWTEXA4200 does move the trailer 10 inches back but when you are making a tight turn (when you'd need it the most), that offset moves to the side and actually brings the trailer back nearly to where it would be without the offset. So an offset on the hitch ball side that doesn't move like the # BWGNXA4085 would give you a more "true" offset when needed. For your 2014 Ford F-250 with a 5-1/2 foot bed you'd want...

    The B&W Turnoverball Underbed Gooseneck Trailer Hitch w/ Custom Installation Kit - 30,000 lbs # BWGNRK1104 is a confirmed fit for your 2004 Ford F-150. With the 5-1/2 foot bed, I do recommend using the 4" Offset Ball for B&W Turnoverball Gooseneck Trailer Hitches # BWGNXA4085 to give you additional turning clearance for most trailers. If your trailer has a rounded front or an offset coupler like # BWTEXA4200 then that wouldn't be necessary, but in most cases with that short bed it is wise.

You will want to check your 5th wheel's pin weight to ensure the 3.5K model is going to be the right capacity though.
