Video Transcript for Curt Hitch Ball - Gooseneck Hitch Ball - C602 Review

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:

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.



by:

Great piece of gear. Very strong and r eliable.



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.

Got what I ordered four days after it was promised

Works great Thank you



by:

This is a must have with 5 1\2 bed



by:


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:

Great product gives 4in more room off truck cab



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 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:

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:

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:

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:

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:

Absolutely loved it! Very happy with my purchase. Everything I thought it would be.



by:

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

Easy to install, gave me the extra clearance I needed.

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

  • Will Reese Gooseneck Hitch Ball with 5 Inch Offset Fit Curt Gooseneck Hitch
    We have some options for you to have an offset for your gooseneck, but the Reese Gooseneck Hitch Ball with 5 Inch Offset # 19308 will not work with the Curt gooseneck hitch in your 2015 GMC Sierra 3500. The # 19308 is designed to work with Reese Hide-A-Goose gooseneck hitch heads. The only Curt offset gooseneck hitch ball we offer is the Curt 4 Inch Offset Ball for Double-Lock Gooseneck Hitch # C602. This hitch ball is designed for use with Curt's Double-Lock gooseneck hitches. If you...

  • What Hitches Does the Curt 4 inch Offset Ball part # C602 Fit
    The Curt 4 inch Offset Ball part # C602 that you referenced is designed to fit Curt Double-Lock, Flip and Store gooseneck hitches. We do not sell a gooseneck extension at this time that will work on the plate style gooseneck hitches. I attached a link to all of the offset gooseneck hitch balls we carry.

  • Recommended Gooseneck Trailer Hitch For A 2010 Chevy Silverado 5.5' Bed
    For a 2010 Chevy Silverado 1500 with a 5.5' bed you'll need the Curt Double Lock, Flip and Store Underbed Gooseneck Hitch # C615-632. This kit will come with everything you need to install a gooseneck hitch in your Silverado, minus the tools. I've attached a video below that will help walk you through the installation process if you're wanting to do this yourself. With you bed being so short you might also consider picking up the Curt Offset Ball # C602 to gain an extra 4" of clearance...

  • Can a 5th Wheel Hitch be Installed on a 2013 Ram Longhorn 4x4 with Air Suspension Package
    Sine your 2013 Ram has the air suspension package you will not be able to install a 5th wheel trailer hitch. The option left is a gooseneck hitch, # C607-658. Ultimately, a gooseneck hitch is going to cost less so that is a positive aspect. If you still wanted to go with a 5th wheel hitch then what you could do is go with the gooseneck hitch above and then use the Curt X-5 adapter, # C16210, which was designed to fit the Curt Double-Lock, Flip, and Store hitches. Using the X-5 adapter...

  • Offset Hitch Ball Fitment for Curt Double-Lock Gooseneck Hitch
    The 5" Offset Ball # 19308 will only work with the Bulldog, Draw-Tite, Hidden Hitch, and Reese Hide-A-Goose gooseneck trailer hitches do to the dimensions of the shank and the location of the hitch pin hole. If you have the Curt Double-Lock Gooseneck Hitch then you can use the Curt 4" Offset Ball # C602 instead as it is designed specifically for this Curt hitch. Unfortunately if you have something different then there isn't a solution for an offset ball, but we might still have an alternative...

  • Offset Hitch Gooseneck Ball and 5th Wheel Trailer to Gooseneck Hitch Adapters
    The Curt offset ball, # C602, is designed for use with the Double-Lock, Flip and Store gooseneck hitches. If you have a different hitch then this ball is not going to fit. You will need to go by the hitch manufacturer to get a compatible ball. If the trailer is a 5th wheel trailer and not a gooseneck trailer then you will need an adapter to be able to tow the trailer. A 5th wheel king pin is not compatible with a gooseneck hitch ball. The best option is the Goosebox, # RP85FR, for Lippert...

  • Gooseneck Ball that Fits Factory Gooseneck of 2019 Ford F-250
    We have hitch balls that fit the factory rail kit of your 2019 Ford F-250 like the part # C60692 but we do not have any balls that fit your rail kit that have an offset like the # C602 that you referenced.

  • How Come Curt Offset Ball # C602 Is Taller than Standard Gooseneck Ball
    Yes, the additional height of the Curt 4" Offset Ball for Double-Lock Gooseneck Hitch # C602 is due to the offset plate needing to be tall enough to fit over the top of the truck bed. The additional height is right right at 3/4 of an inch like you stated.

  • Is There An Offset Hitch Ball to Fit the OEM Hitch on a 2019 Ford F-350?
    There is not an offset hitch ball to fit the OEM gooseneck hitch on your 2019 Ford F-350. Instead you may be interested in the B&W Extend-A-Goose Gooseneck Coupler - 2-5/16" Ball - 10" Offset - 24,000 lbs # BWTEXA4200. There are also shock absorbing couplers that give you a 5-1/2 inch offset from Gen-Y. I've linked the page to these options to assist.

    The only gooseneck hitch and install kit we offer that has been confirmed to fit your 5-1/2 foot bed 2006 Chevy 1500 Silverado is the Curt Hitch and Install kit part # C60712. This comes with the hitch and rail kit so there wouldn't be any additional products needed for installation. For added clearance you would also want the part # C602.

  • Recommended Offset Gooseneck Ball for a Curt Double Lock Gooseneck Hitch
    Unfortunately no, Tom. The 5" Offset Ball for Hide-A-Goose Gooseneck Trailer Hitches # 19308 only works with Bulldog, Draw-Tite, Hidden Hitch, and Reese Hide-A-Goose gooseneck trailer hitches. For your Curt Double-Lock, you'll want to use the Curt 4" Offset Ball for Double-Lock Gooseneck Hitch # C602. You'll notice this one has a 4" offset, but that's because they don't offer a 5" offset version, so this is the best we can do.

The Curt offset ball only fits Curt Double-Lock gooseneck hitches. The other offset balls we have are also manufacturer specific and I am unable to find one made by Ecortic. I recommend the B&W Extend-A-Goose Gooseneck Coupler - 2-5/16" Ball - 10" Offset - 24,000 lbs item # BWTEXA4200. This coupler fits most trailers with a 4" diameter outer...

  • 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...

  • 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...

    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...

    You are going to need to remove the air bags in your 1999 Dodge Ram in order to install the Curt Double Lock, Flip and Store Underbed Gooseneck Hitch w/ Installation Kit # C60734. The air bag kits we offer for this truck are not compatible with any type of in-bed hitch, whether that is a gooseneck or a fifth wheel.

    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 GM towing prep package. The problem is the Curt and B&W system either have a rod that goes through the base or the gooseball channel is square. Without this pin to hold the gooseball in place any offset ball would just spin in the hole when you make a turn. To get the clearance you need for your 2019 Chevy...
