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

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.

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:

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:

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:

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:

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



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:

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:

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:

  • Recommended Curt Gooseneck Hitch for 2018 Chevy Silverado 1500 with 5-1/2 Foot Bed
    I do have a solution for you, however the Curt Double Lock Underbed Gooseneck Hitch # C607-604 referenced in your question is only designed to fit the 2018 Silverado 2500 or 3500 that features a longer bed. It will not work on your Silverado 1500 that has the 5-1/2 foot bed. For the Curt Double Lock Gooseneck Hitch that is designed to fit your truck you instead need the part # C615-632. This is confirmed to fit and includes custom brackets that use existing holes in the truck's frame...

  • Is Curt Gooseneck Hitch C60733 for 2006 Dodge Ram 1500 Compatible With Air Lift Air Bags AL57230
    I double-checked for you and can confirm that the Air Lift LoadLifter 5000 Air Helper Springs # AL57230 on your 2006 Dodge Ram 1500 are completely compatible with the Curt Double Lock, Flip and Store Underbed Gooseneck Hitch with Installation Kit # C60733. This is a really nice option for a hitch because it uses two pins to hold the hitch ball in place for added security, and is a below-bed mount which means you'll have a nice, clean bed when you aren't using the hitch for towing.

  • Gooseneck Hitch Ball Recommendation for Curt Gooseneck with Taller Height
    Since you have a Curt gooseneck hitch the best option we have would be the Curt 4 inch offset double lock ball part # C602 which has a 4 inch offset and sits taller than the standard hitch balls.

  • 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,...

  • Installing the Curt Underbed Gooseneck Hitch on 1993 Ford F-250
    You can install the Curt Double Lock Underbed Gooseneck Hitch w/ Installation Kit # C60723 in your 1993 Ford F-250 without removing the truck bed. The majority of the installation involves mounting the brackets to the frame and that is done from underneath the truck. You will need to drill a 4" hole in your truck bed though for the gooseneck hitch. Also, if you have overload springs, this hitch requires drilling two holes into the frame. If you want to use this truck for fifth wheel...

  • 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...

  • 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.

  • 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.

  • 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.

  • 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.

  • 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...

  • 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.

  • Are Ford and Ram OEM Gooseneck Hitch Compatible with Offset for Better Turning Clearance
    The Curt 4" Offset Ball for Double-Lock Gooseneck Hitch # C602 is available only if you have the double-lock model. 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.

  • 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.

This is due to the fact that the Curt ball mounts for gooseneck hitches are circular in shape whereas the ball mounts for B&W gooseneck hitches are square.
