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..

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. 569506

When you order products from etrailer you won’t be disappointed. A real live person actually answers the phone!!!

I definitely recommend etrailer !!! 605349

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. 695540

Ask the Experts about this Curt Trailer Hitch Ball

  • 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.

  • 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 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.

  • 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.

  • Will A Curt Offset Gooseneck Ball Fit Into A B&W Gooseneck Hitch
    I called my contact at Curt Manufacturing and they confirmed that the Curt 4" Offset Ball for Double-Lock Gooseneck Hitch part # C602 will not fit into the gooseneck ball location on a B&W gooseneck hitch such as the B&W Turnoverball Underbed Gooseneck Trailer Hitch part # BWGNRK1012. 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. In order to gain a 4" offset with the B&W gooseneck...

  • 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, # RP94716, for Lippert...

  • 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...

  • 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...

  • Recommended Gooseneck Trailer Hitch Extender For 2016 Ram Truck With Short Bed
    We do offer offset gooseneck hitch balls but they are designed for specific gooseneck hitches. If you have a Hide-A-Goose Underbed Gooseneck Trailer Hitch, I recommend part # 19308. This extender has a 5-inch offset. If the gooseneck hitch in your truck is B&W Turnoverball hitch, the 4-inch extender I recommend is Part # BWGNXA4085. If you have a Curt Double-Lock, Flip and Store gooseneck hitch, then the 4-inch extender I recommend is part # C602.

  • 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.

  • 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.

  • 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.

  • Gooseneck Ball that Fits Factory Gooseneck of 2019 Ford F-250

  • Gooseneck Clearance Equation and Offset Ball Options for 2017 Ford F-350 Short Bed
    For your 2017 F-350 short bed, the clearance calculation is the measurement from the cab to ball center minus 1/2 the trailer width. This will give you the minimum clearance. If that number is positive the trailer will not interfere with the cab of the truck, but if it is negative then it will interfere and you need to be extremely cautious. We do have offset hitch balls that are hitch specific to gain more clearance and we also have the B&W Extend-A-Goose Gooseneck Coupler - 2-5/16"...

  • 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,...

  • Solution for Towing a 5th Wheel Trailer with Curt Double-Lock Hitch on 2017 Chevy Silverado 2500
    While we do have other options for you, the only way to use the B&W Companion # BWRVK3500 or # BWRVK3400 is by having the entire B&W Gooseneck Hitch # BWGNRK1016 installed on your 2017 Chevy Silverado 2500 as there isn't a way to safely fit different parts of gooseneck hitches together. With that being said, I'm a little curious about the gooseneck hitch you currently have installed.

    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.
