Video Transcript for Complete Breakdown of the Curt 4" Offset Ball for Double-Lock Gooseneck Hitch

Speaker 1: Today we're going to take a look at the Curt Four Inch Offset Ball for the Curt Double Lock Gooseneck Hitches. Now what happens when you need to pull a gooseneck trailer that has an especially long front over hang, well without the right amount of clearance between the overhang and your truck cab, tight corners can get to be a little tough. This Curt Double Lock Gooseneck Offset Ball will easily slide into any double lock gooseneck hitch and it sets your coupling point four inches back of the original trailer ball hole.The offset gooseneck trailer ball secures in place just like any other compatible gooseneck ball, using the double lock's dual pin locking system. Again, this extension will provide four inches of additional space between your truck's cab and your gooseneck trailer. The ball itself is chrome plated. The base is a durable black powder coat finish.

And again, this item is designed for use in the Curt's double lock gooseneck hitches. The part is made in the USA, the ball size, the gooseneck ball is a standard two and five-sixteenths diameter. Again the offset, which we measure from where it goes in to the hole to the center of the gooseneck ball, is going to be right at four inches. Weight capacity on this is 20,000 pounds. Vertical load capacity is 5,000 pounds, but you do want to make sure it never exceeds your vehicle's maximum gross weight rating.But that should do it for the review on the Curt Four Inch Offset Ball for the Curt Double Lock Gooseneck Hitch..

Gave me enough added turning radius that maneuvering my 5th wheel became so much better when backing into those tight camping site. Excellent quality and have recommended this to many of my camping buddies



by:

Not bad to install I really like the Curt hitch and offset ball, great price fast shiping would not hesitate to buy from etrailer again. The offset ball helped a lot, I didn't think I would be able to leave tool box on truck but had plent of clearance.



by:

I sold my pick up and never used it. I still have it and I really like that it would of made my trailer not hit the tail gate with I was hooking up my fifth wheel.

Great piece of gear. Very strong and r eliable.

Works great Thank you

This is for my 4' square hole trailer
hitch extension. I love the fact that I can turn my trailer without breaking the back window. I had never seen a square hole before and this item came that way. I only wish they did one 6"-8" longer. But so far so good.



by:

This is a must have with 5 1\2 bed



by:

Great product gives 4in more room off truck cab



by:

When you order products from etrailer you won’t be disappointed. A real live person actually answers the phone!!! Lisa answered our call and was friendly, curteous and very knowledgeable about the hitch extender I needed. She said it would arrive Tuesday and IT DID!!! I definitely recommend etrailer !!!



by:

The hitch is made really well and seems to be heavier than the b&w one I had in another truck. The offset makes it easier to pull a gooseneck trailer with my shortbed truck and gives me a better turning radius.



by:

I can use this with my offset hitch to get more clearance on my truck

It works great and really glad I bought it with my shortened truck



by:

Everything installed as advertised. Did all on my own just take your time and you will be fine also. 2006 duramax crew cab use for horse trailer and flatbed gooseneck.



by:

Excellent solution! Installed on 2010 Dodge Ram 1500 quad cab. Now I won't hit cab of truck with 5th wheel camper!



by:

The Curt goose neck hitch is a great product built very well. etrailer was a pleasure to work with delivering the product to my doorstep on time and complete. I would definitely use them again in the future.



by:

I usually pull my trailers with a long wheelbase truck but my newest truck is a short bed. The hitch is too far forward but this works perfect pulling the horse trailer.



by:

Needed a little more room for the square front on the trailer. I was surprised how much sharper I can turn comfortably with only 4 inches more set back. Shopping on etrailer sight was easy and enjoyable.



by:

Got what I ordered four days after it was promised



by:

Great product from curt... Drops right in..
Shipping was on time... A+++
Needed for the short bed!!



by:

The hitch fit like it was supposed to. It has load limits on the hitch and the ball so you cannot forget it. I like that.



by:

Great product from curt... Drops right in..

Works well to give needed room for short box pickup and Fifth wheel camper.



by:

this isn't my first order from etrailer, always fast delivery and great prices. Products are as described on page and so far all have been solid quality parts.



by:

Heavy Duty! Works great to give me the extra inches I need for clearance in my short bed truck.

  • Does Wheel Well of 2001 Dodge Ram Need to be Cut to Operate Underbed Gooseneck Hitch Ball
    To activate the lever for the underbed gooseneck ball, you will need to cut the wheel well liner of your 2001 Dodge Ram when you install the underbed Curt Double Lock, Flip and Store Underbed Gooseneck Hitch with Installation Kit # C60734. This is needed for you to be able to easily reach the hitch ball's lever.

  • USA Made Gooseneck Hitch Recommendation for a 2011 Ford F-250
    Both of the gooseneck hitches you mentioned would work well for you, but since you asked about which is made in the USA I would recommend the Curt part # C60720 as it is made in the USA and the Draw Tite is no longer made here. Since your truck is a short bed you will want the offset part # C602 to give you additional clearance. For a 7-way to install in the bed of your truck to make connecting your trailer lights easier you would want the part # 41157. Most 7-ways will be at the rear...

  • Recommended UnderBed Gooseneck System for a 2016 Chevy Silverado 2500
    Between the B&W and Curt underbed systems for your 2016 Chevy Silverado 2500, I recommend the B&W Turnoverball Underbed Gooseneck Trailer Hitch w/ Custom Installation Kit item # BWGNRK1016 based on B&W's reputation in the towing business, their amazing customer service, and warranty. The Curt EZr Double Lock Underbed Gooseneck Trailer Hitch item # C611-624 has an identical towing capacity to the B&W at 30,000 lbs and installs in basically the same way. They both include a gooseneck ball,...

  • Gen-Y 5th Wheel To Gooseneck Pin Box For A 2023 Grand Design Reflection 341RDS
    Hi Vince, Gen-Y switched production to the newer Snap Latch in December 2023 so anything manufactured from January 2024 and forward would come with the new latch. This is a direct-ship item so you'd be getting it directly from the factory, which would lead to a greater chance that you'll get the Snap Latch since we almost a few months into the year. To determine if this is the correct fit for your Reflection you'll need to determine the bolt pattern for the trailer as well as the fully...

  • Gen-Y 5th Wheel To Gooseneck Pin Box Compatibility With A Rhino Box Pin Box
    Hey John, The Gen-Y Hitch 5th Wheel to Gooseneck Pin Box # GY98GR has a matching bolt pattern to your Rhino Box pin box. 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. With a 6.5' bed you're not going to be able to make a 90 degree turn unless your trailer has a really tapered nose. You can, however, use an offset ball to help provide more turning clearance though. These all have specific fits to the gooseneck hitch...

  • Solution For Offset Gooseneck Ball Needed for Use with Ford OEM Gooseneck Hitch
    I may have a solution for you to use your factory gooseneck setup, but there is not an offset gooseneck ball like the Curt 4" Offset Ball for Double-Lock Gooseneck Hitch # C602 designed to fit on the factory Ford prep package. With that said, you can eliminate the Andersen Ultimate # AM3200 and use the Ranch Hitch Universal 5th-Wheel-to-Gooseneck Coupler Adapter w / 8" Offset for Short-Bed Trucks # AM3139; this adapter connects directly to your 5th wheel kingpin and allows you to couple...

  • B&W Gooseneck Offset Coupler for a 2019 Chevy Silverado 2500 w/ OEM Prep Package
    I have a solution for you but I am sorry the only offset balls that are available are for Curt's underbed package and B&W's turnover ball system. No one makes offset balls that fit the OEM prep packages. To get the clearance you need for your 2019 Chevy Silverado 2500 you are going to want the B&W Extend-A-Goose Gooseneck Coupler - 2-5/16" Ball - 10" Offset - 24,000 lbs item # BWTEXA4200. The sturdy inner tube pairs with existing outer tube to create a gooseneck coupler for hooking your...

  • Comparing Curt Double Lock Gooseneck Hitch # 60720 to # 60683
    The Curt Double Lock # C60720 and the Curt EZr Double Lock # C60683 are basically the same gooseneck hitch. The difference is in the installation. The EZr gives you the ability to ensure the hole you drill in the bed is perfect without the need to measure. It instead uses the Center locator tool that allows you to drill from the bottom up for a perfect fit. The regular Double Lock system simply requires measuring and then you drill from the top down. If you are good with a tape measure,...

  • Availability of Offset Gooseneck Hitch Ball for 2019 Chevy Silverado 2500 HD with Short Bed
    If you have the OEM puck system on your 2019 Chevy Silverado 2500 HD then the only way to get an offset for your gooseneck trailer is by swapping out the coupler with something like the B&W Extend-A-Goose Gooseneck Coupler # BWTEXA4200 as there aren't aren't offset gooseneck balls like the Curt # C602 you referenced for the pucks. On the slight chance that you don't have the OEM puck system on your pickup I recommend installing the B&W Turnoverball # BWGNRK1016 so that you can use the...

  • Offset Gooseneck Ball Hitch Options For a 2020 Chevrolet Silverado 2500HD
    The Curt Custom Underbed OEM-Style Gooseneck Trailer Hitch # C60642 on your 2020 Chevrolet Silverado 2500HD will not allow for a offset ball. This is due to it not having a locking pin that travels through the shank of the ball like the Curt EZr Double Lock # C65HR or B&W Turnoverball # BWGNRK1020. Of these systems I recommend the B&W Turnoverball # BWGNRK1020 as the best option. You are able to store the ball in the same hole by simply turning it over to get a flat bed. And you can drop...

  • How Much Does The Curt Double Lock, Flip and Store Underbed Gooseneck Hitch # C60721 Weigh?

As I see you have a 2014 Ford F-150 short bed truck you should consider adding the Curt RockerBall Shock Absorbing Gooseneck Hitch Ball # C67DR as this will reduce a lot of the shock transferred to your truck. We also have the 4" Offset Ball # C602 if you need the additional clearance.

  • Which Offset Gooseneck Hitch Ball Will Fit the Factory Prep/Puck Hitch In My 2021 Ram 3500 Dually?
    To use a offset gooseneck ball on your 2021 Ram 3500 you will need to replace the factory gooseneck hitch with a B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1320. The B&W hitch mounts in the same place as the factory hitch, and does not affect the outer 4 mounting holes for a 5th wheel hitch. This will allow for you to use their 4" Offset Ball # BWGNXA4085. You can use the Reese Safety Chain Holder # RP30145 in the factory puck holes if you do not want to drill for the safety...

    It sounds to me like you have a 5th wheel to gooseneck adapter like the Ranch Hitch Universal 5th-Wheel-to-Gooseneck Coupler Adapter part # AM3100 already installed on your 5th wheel trailer. To answer your question, yes, a 5th wheel to gooseneck adapter is compatible with an offset gooseneck hitch ball.

  • Do I Have Enough Clearance On my Ford F250 6 ft bed to Turn Sharp with a Gooseneck Trailer
    In order to determine if you will have enough clearance or how much of an extension would be required to safely execute a 90 degree turn you will need to take a few measurements and use the following formula. The formula looks like this: (A + B) - C = Clearance Where A equals distance from center of gooseneck coupler to truck cab, B equals the distance in front of or behind the the front of your trailer the center of the coupler is. So if there was an overhang on the front of the trailer...

The other Curt models that drop in and lock through the ball lever like # C60601 featuring the Pop-In or OEM Underbed System will not have the offset option available, so it is a bummer the dealer didn't give you what you asked for with your 2018 Ram 2500 Laramie.
