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..

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:

Got what I ordered four days after it was promised



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:

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

Curt 4" offset ball Haven't had a chance to use it. Looks as if it will fill my needs

Works great Thank you



by:

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



by:

This is a must have with 5 1\2 bed



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:

Great product gives 4in more room off truck cab



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:

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:

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:

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

Chris

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



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..
Shipping was on time... A+++
Needed for the short bed!!



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:

Great product from curt... Drops right in..
Shipping was on time... A+++

Fit perfectly with my spray in bed line r.

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

See what our Experts say about this CURT Trailer Hitch Ball

  • 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.

  • Increasing the Clearance of an Andersen Ultimate 5th Wheel Hitch with an Offset Ball
    I called Andersen to confirm. If you are wanting more clearance for your Andersen Ultimate 5th wheel hitch, then using an offset ball like the Curt 4" Offset Ball for Double-Lock Gooseneck Hitch, part # C602, is exactly what you need. This should work perfectly for you. I've linked to a video review of the offset ball for you to look at.

  • 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.

  • Why isn't There Offset Gooseneck Ball that Fits 2019 Ford F-250 OEM Gooseneck
    The reason there are no offset gooseneck balls that fit the OEM gooseneck hitch of your 2019 Ford F-250 is because the shape of the gooseneck ball that fits your hitch being round. Since it's round and can rotate in the hitch any offset could rotate forward and offset in the wrong direction. This is why it's only the square shank balls that can have an offset.

  • 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...

  • Can the CURT Offset Gooseneck Ball for Double-Lock Gooseneck Hitches be Turned 180 Degrees
    I spoke with my contact at CURT about the orientation of the Offset Ball for Double-Lock Gooseneck Hitch, # C602. He stated that it can be inserted either way, to be closer to the cab or closer to the tailgate. You will be able to lock it in in either position.

  • 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...

  • Gooseneck Ball Compatible With 2017 Ford Super Duty Truck with Factory Rail Kit
    The Curt 4" Offset Ball for Double-Lock Gooseneck Hitch # C602 will not fit a factory gooseneck system. The Curt Ball and Safety Chain Loop Kit for Chevy, Ford, GM, and Nissan Underbed Gooseneck Trailer Hitch # C60692 is the proper fit for your 2017 Ford Super Duty truck. There is not an offset option available at this time.

  • 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 To Get More Turning Clearance Using the Curt Double Lock Gooseneck Hitch for a 2000 Ford F-350
    The Curt Double Lock, Flip and Store Underbed Gooseneck Hitch part # C60720 which is a fit for a 2000 Ford F-250/F-350 can only be installed one way. Therefore, you can't flip the center section to get more turning clearance. That said, I do have an option for you to increase turning clearance and that is to use the Curt 4" Offset Ball for Double-Lock Gooseneck Hitch part # C602 which will provide an extra 4" of offset.

  • Will Gooseneck Hitch fit 1999 Dodge Ram with Air Bags
    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. If you do decide to remove the air bags, the Double Lock gooseneck is a fantastic option. It gets its name from the two pins that lock the hitch ball in place offering you...

    The Curt Ball and Safety Chain Loops Kit for Ram Underbed Gooseneck Hitch # C60618 is the confirmed fit for your 2017 Ram 3500 with Factory Rail Kit. The Curt 4" Offset Ball for Double-Lock Gooseneck Hitch # C602 is only compatible with aftermarket gooseneck hitches that have the pull pin on the side of the bed.

  • Needing a Gooseneck Hitch to Fit a 2012 Ram 1500 w/ 5-1/2 Foot Bed
    For the 2012 Ram 1500 with the 5-1/2 foot bed, Curt Double Lock, Flip, and Store Underbed Gooseneck Hitch, # C60730, is compatible for your vehicle per the installation instructions. Since your vehicle has the short bed, I recommend The Curt 4 Inch Offset Ball, # C602. This offset ball will provide you with an additional 4 inches of space between your gooseneck trailer and the cab of your Ram 1500.

  • Offset Hitch Ball for a 2017 Ram 2500 with Factory Puck System
    I do have an option for you but they do not make an offset gooseneck hitch ball that will work with the factory puck system on your 2017 Ram 2500 which includes the Curt 4" Offset Ball for Double-Lock Gooseneck Hitch part # C602. Instead, you are going to want to use the B&W Extend-A-Goose Gooseneck Coupler part # BWTEXA4200 which fits most trailers with a 4" diameter outer tube and will provide you with a 10" offset. I have attached a review video for you as well.

  • 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.

  • Is There an Offset Hitch Ball for the Ram Factory Prep Package
    I do have an option for you but there are no offset gooseneck hitch balls for the factory prep package. The only option we can offer you and I do mean only is a sliding fifth wheel hitch. The fifth wheel hitch we offer with the most amount of travel is Demco Hijacker Autoslide 5th Wheel Trailer Hitch part # DM8550040 which is an automatic sliding fifth wheel hitch that offers up to 22-1/2" of front to back travel.

  • How to get Gooseneck Ball Offset on a GM Towing 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 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...

  • Offset Gooseneck Ball Recommendation for Draw Tite Hitch in 2016 Ram 3500
    If the gooseneck hitch you had was the Draw Tite Hide-A-Goose style of hitch the offset gooseneck ball part # 19308 would fit and work well. The hitch you'd have to have installed in your 2016 Ram 3500 would be the part # 9466 which is the correct fit for your truck. Reese does not make a gooseneck hitch for your truck but Draw Tite and Reese are made by the same company.

  • How Does Offset Gooseneck Ball C602 Install in a Gooseneck Trailer Hitch
    Part # C602 is an offset gooseneck ball for a Curt Double-Lock, Flip, and Store gooseneck trailer hitch. It would install the same way as the regular ball by inserting it into the gooseneck ball cavity and then putting the handles in the locked position. As for the hitch itself I would need to know the year, make, and model of the truck and then I can determine the correct hitch and link the installation instructions for you.
