Is this right for you? Product Expert Kathleen M says:

Yes, if you:

  • Feel reassured by the double-pin design that locks the hitch ball into place and prevents rotation
  • Prefer not to cut the pinch weld in the wheel well of your truck to install the cross brackets

No, if you:

  • Have an aftermarket exhaust system that limits the space between the truck bed - you might have to store the hitch ball in your truck
  • Plan to install this kit yourself and have zero patience for vague instructions

Curt Double Lock Gooseneck Hitch Operation

Curt Double Lock Gooseneck Trailer Hitch Operation

The Curt Double Lock underbed gooseneck trailer hitch provides a sturdy, secure connection for towing your gooseneck trailer and also allows for a clean, unobtrusive look for your truck bed when you aren't towing. To tow, simply pull the included handle out to unlock the hitch. Then insert the chrome-plated hitch ball into the ball hole. You may need to rotate the ball to line it up with the dual locking pins. When the ball drops into place, rotate the handle counterclockwise until the locking pins snap into position. Because there are 2 locking pins instead of 1, you get extra security for your towing setup.

Get full bed access when you're not towing. Just remove the ball, flip it upside down, drop it back into the ball hole of the hitch, and use the handle to lock the ball in place. A rubber cover is included with the Double Lock. When the ball is stowed upside down in the hitch, place this cover over the ball hole to keep out dirt and grime and create a clean look for your vehicle.

this installed correctly on my 2005 dodge ram 2500 diesel per instructions for installation with air bags. I have hauled a 42 foot 3 axle car trailer for over 6,000 miles with no issues. This was a great purchase. Thank you


The customer service is fantastic! William is always on top of it, every time I call! We look forward to doing a lot more business together.


Good quality product. Easy installation.


works great, have a B&W in my other truck, went with the Curt for this one. The Curt unit seems as well built and as well designed as the B&W, with heavier retainer pin. Glad i tried the Curt option.


I have used this gooseneck hitch numerous times since purchasing it. It does require some tedious measurements to install it correctly. If you are doing this yourself, i would say you habe at least 3 hours of work ahead of you. With a helper it took me around 4 moving slowly and dekiberately. The ball is excellent, and the locking mechanism is as well. I also purchased the 5th wheel rail plate adapter. The combination has been hard to beat for the cost. Overall i would recommend this product. It is very well built and seems to hold up well with hard use.


The products from have been just what I needed. The site does a great job of describing exactly what I needed for my truck and the products are of super high quality. One interesting note however was the instructions that came with the installation kit said a pro could install the hitch in 45 minutes. I would like to see that! We had no issues and I had reviewed 4 videos prior and downloaded a PDF instruction sheet prior to starting and we spent 5 hours putting this hitch and installation kit in. It was a fun project with my son helping, and we ran into no issues that slowed us down, but you've gotta ignore the time estimate on the installation documentation. It's a beautiful thing all things considered.


Great, heavy duty hitch. Great service from etrailer.

2012 Ram 3500

Curt and Pollak make a great product and etrailer is a great site, I come here for all my towing needs now! My only issue is that the instructions for the gooseneck hitch were kind of vague. I got it on in about 3 1/2 hours taking my time and making sure it was right. Other than that I would purchase a Curt and Pollak product again!

2006 Dodge Ram Pickup

Install on my 2006 2500 Dodge Ram Big Horn, easy enough considering no lift. Works good, only problem is that when you turn the ball over for storeage, bottoms out on the axle. Other than not being able to store the ball as advertised, good buy for the money.


Great product. Easy installation and works great


Product arrived in a timely manner. Installed just as the instructions stated. Products work just as advertised.


Fast shipping! Product quality is great. The instructions were adequate but could be better. Would definitely buy from etrailer again.

2013 Ford F-250 and F-350 Super Duty

Shipping was fast, ordered on Monday and received it today on Wednesday, haven’t opened anything yet so hopefully all is there


Easy to install. Fast shipping.



great item,,easy install,,,


Review from a similar Double Lock in Gooseneck Hitch

Ordered this after deciding to go with it over a B&W kit due to me not using it a whole lot and the price difference. When I received the package 1/2 the hardware was missing because the inner box it was in was all broke apart and the outer box was not sealed up. So I would have to give the packaging and shipping one star because I had to go spend an extra $75 on grade 8 hardware. The paper directions were not totally clear on several thing so we resorted to the video which helped a lot. The two large carriage bolts that go in the rear cross member are a little deceiving because the video makes it seem like they slip right in. However, the heads were larger than the pass through in the frame rails so it took quite a bit of extra time and ingenuity to get those fished through there with the plates.(The carriage bolts survived shipping so they were what came with the kit). In the video it showed where he cut a large u out of the inner fender to clear the pull handle and notched the bed that looked kind of sloppy. With a few extra measurements you can just cut a hole in both for handle to slide through and give it a much cleaner look. Definitely recommend putting a bolt through receiver holes and using a strap to hold up center plate through hole in bed after you get it into place. Makes life a lot easier until you get the bolt ls in. Overall this hitch works and functions great. Install went pretty smooth with two people and I would recommend it to anyone needing a hitch.


Review from a similar Double Lock in Gooseneck Hitch

I installed the Curt gooseneck on my 1993 GMC 2 Wheel Dr. 2500 truck. All the components have tight tolerances. It took me eight hours. With a socket and the wrench. Laying on my back. I did have to cut the wheel well lip about 3/8 of an inch off because I could not get that front angle bar to slide in without hitting it, no way around it unless you lift the bed up and I wasn’t going to do that!!. You have to cut it.instructions do not state that. I’m very happy with the Hitch, it is definitely stout! I did have to make a notch on the outside brackets to go over my airbag bolt. I also had to remove the support bracket on the inside of the frame for the airbag and the crossmember for the spare tire to get the front angled bar in.


Review from a similar Double Lock in Gooseneck Hitch

Thank you for reaching out. Definitely love the reliability and durability of this hitch, also the added clearance. I have it mounted on my 40 foot enclosed race car trailer. We towed using it 35 to 40 times to and from race tracks in 2019. Hooking it up and disconnecting it every weekend. Never gave us a single issue.


Review from a similar Double Lock in Gooseneck Hitch

Great product and perfect fit for my 2005 GMC Sierra duramax. I just purchased a Montana fifth wheel and wanted to still be able to use the bed of the truck without taking a heavy hitch in and out and breaking my back. The hitch arrived really fast and the boxes were in pretty good shape and I was only missing one washer from a torn parts bag. I was able to install the hitch that weekend with help of the directions and how to YouTube video. The only issue I had was that the video stated the crossbar with the notch went to the rear while the directions showed it going to the front. It definitely goes to the front and was pretty obvious when installing it. I didn’t have any real issues with the install and it looks great and hides away nicely leaving a clean flat bed. I look forward to hauling my fifth wheel real soon.

In order to tow your fifth wheel trailer with your new gooseneck hitch, youll need an adapter of some sort. If you use the provided link, you can see the various options available.

Great addition to my towing needs. I have taken the hitch out many times and it has always performed well.

Review from a similar Double Lock in Gooseneck Hitch

My hitch was delivered very fast, all necessary hardware and instructions were complete. It bolted up easily in my Silverado. The only thing not provided was a 4 inch hole saw for the hole in the bed. Installation was very straightforward and it has preformed flawlessly since I installed it.


Review from a similar Double Lock in Gooseneck Hitch

Installed easily on 2015 GMC 2500 HD double cab short bed. Plenty of clearance under the bed when ball is flipped. This system makes for a clean useable bed. When I was purchasing this I was concerned about clearance of a gooseneck hitch and my transfer tank. I have a 40 gal tank that sits back from the cab a bit over 20 inches, there’s plenty of clearance for a gooseneck with a fuel tank on this short bed. The hitch has held up perfectly over the last year. I haul around 12k on steep, washboard, gravel roads.


Review from a similar Double Lock in Gooseneck Hitch

Im sure the hitch will work as it should i have installed a number of curt hitches the reason its not 5 stars is because shipping not etrailer or curts fault but the carrier dosent take care of packages at all only problem os some bolts are missing but i can pick up ay the hardware store


Review from a similar Double Lock in Gooseneck Hitch

Kit installed easily and fit perfectly. Instructions could have been better or included more pictures, but watching a few videos of similar installs online helped. Lost one star because the kit was missing an exhaust hanger bracket and a couple other pieces that were considered optional and fortunately not needed during my install.


Review from a similar Double Lock in Gooseneck Hitch

Haven't used it yet but I'm sure it will perform just fine. Install was a pain but not technically difficult as long as you follow the video, the provided instructions aren't very helpful. I managed to remove and reinstall the exhaust heat shield instead of cutting it unlike one of the videos suggested. But the provided template for drilling the hole in the bed is very helpful and confidence building (I don't think the comparable B&W provides one, just measurements). I also like the double latch system on the ball and especially the hideaway feature. It is finished nicely with chrome, rubber ring for the bed, and black cap so it looks great as well inside the bed. I was missing some bolts and washers but etrailer sent them out ASAP! The only gripe of the product I have is they didn't utilize the factory weld nuts on my truck's frame for the factory installed hitch which would make the install a little easier/cleaner, and instead make you fish a bolt an washer through the frame. Probably a reason for that or maybe an oversight. But overall happy so far

  • Replacing Hitch of 2004 Dodge Ram 3500 that Had B&W Turnoverball Installed
    The gooseneck ball hole won't be in the exact location going from the B and W setup to the Curt setup so your best option would be to install the same hitch that came out of the truck part # BWGNRK1313 which is widely considered to be the nicer hitch setup than the Curt and because it would minimize additional cutting of truck bed. There wouldn't be any other hitch option that's going to fit in exact same hole as what you have now aside from the B and W. I attached an install video for...

    I do have an available option for you but there is no direct fit gooseneck applications for a 2011 Ram 5500 since they don't come with standard truck beds. Instead you can use The B&W Turnoverball UnderBed Gooseneck Trailer Hitch For Flatbed Trucks # BWGNRK1500 and have a fabrication install this for you.

  • Which Curt Gooseneck Hitch Fits 2003 Dodge Ram 2500
    Curt does offer gooseneck hitch kits that fit your 2003 Dodge Ram 2500 but none that use the # C61100. Instead you'd need a hitch like the part # C607-661 which comes with the rail kit that's custom fit for your truck and a gooseneck hitch plate that allows you to flip the ball over and store it out of the way when not in use.

  • Gooseneck Hitch Recommendation 2003 Dodge Ram 2500 Short Bed
    The B and W Turnoverball gooseneck hitch part # BWGNRK1313 is the best option we have for your 2003 Dodge Ram 2500 as it requires no drilling to install, is easy to use and very reliable, the ball flips over, and has a 30k capacity. It also easily converts to a fifth wheel hitch with the Companion part # BWRVK3400 as well. For a somewhat similar option the Curt part # C607-661 that you referenced would work as well but the passenger side wheel well does need to get notched.

    Whether or not the B&W Turnoverball Gooseneck Hitch # BWGNRK1313 for the 2005 Ram 2500 you're working on is worth the higher cost is in large part dependent on application. The Turnoverball is an excellent, durable, and reliable gooseneck hitch, but a decent part of its appeal is its compatibility with the B&W Companion # BWRVK3400, which is one of the nicest 5th wheel hitches on the market and is designed to drop right into the square gooseneck ball hole that the Turnoverball provides....
