Curt EZr Double Lock Gooseneck Hitch Operation

Curt EZr Double Lock Gooseneck Trailer Hitch Operation

The Curt EZr 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 EZr 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.

Curt Center Locator Tool

Curt Center Locator for Double Lock Gooseneck Trailer Hitch

The innovative center locator tool included with this gooseneck trailer hitch is designed to make installation fast and easy by eliminating the need to measure where the ball hole must be cut into your truck bed. Once you have the custom installation kit in place and the gooseneck hitch is properly attached to the rails, the bright orange locator will help you to finish installation.

Curt Center Locator for Drilling Pilot Hole

Use the hole at the center of the locator to line up your 3/16" drill bit, and drill up from beneath the bed to create a pilot hole. This pilot hole will be your guide as you cut the 4" diameter ball hole into your truck bed.

Curt Center Locator for Drilling Ball Hole in Truck Bed

When you begin cutting through your bed, the locator will act as a trim shield, ensuring that you don't drill too deep. Continue cutting from the top of your truck bed until orange shavings appear. Once you see these shavings, you've gone far enough. The center locator can be easily removed from the hitch once installation is complete.

Video Transcript for Curt EZr Double Lock Underbed Gooseneck Hitch Review

Hey, everybody. Ryan here at etrailer. Today, we're gonna be checking out the CURT Double Lock underbed gooseneck trailer hitch kit. By having a gooseneck trailer hitch back here, it's gonna allow you to hook up to all those different types of trailers. Whether you're trying to pull a camper around, or a car hauler, whatever you might have, you want a reliable hitch that is gonna provide us with a really secure connection point. That way, we can safely tow whatever we're pulling down the road and a kit like this is gonna do just that.

One of the really nice things is you're still gonna have pretty much full bed access, right So, the only thing that's gonna be taking up really any space is just your safety chain hooks there, but they're spring loaded so they sit pretty much flush anyway. The ball can be flipped over and stored like that, and they even give you a cap to put over it. And so, you're not losing really any of your bed space at all. And that's honestly what our neighbor here today was kind of sick of. So, you can probably see the discoloration in the bed.

He actually had 5th wheel rails in here and needs to pull a gooseneck, right Well, there's a lot of different things now you can convert. There's parts you can use to convert your 5th wheel rails into a gooseneck and so on but he's sick of having all this stuff in the back, right So, getting rid of that. Putting in this gooseneck hitch, gonna free up all that space and allow him to help pull his trailer down the road. I do like the operation of the handle and I feel like that double lock mechanism is partly due to that. Kind of just keeps everything gliding the way it should, but super easy to operate.

So right now, it's in the locked position. So the ball, you wanna be able to remove it or put it in or anything. If you're ready to flip it over to tow or flip it over to store it, just pull this out of the ways, rotate it to left just a hair, and it'll stay open for you. That way, you can go in there do what you need to do and then lock it back in. Since this hitch does sit underneath of our bed, it keeps everything free up top and this is what it's gonna look like.

So, it doesn't interfere with anything or anything along those lines. One of the things that does kind of separate this hitch from some of the others is it has a double locking pin here. So, we can see one of them. The other one's just further up top. So, it has two pins. Kind of double the security there and double the strength. And that's not something you see on a lot of these types of hitches. So, it definitely isn't gonna hurt anything and the more the better, at least in my opinion. The center locator tool is going to be a one time thing that you'll use during the install. I think this thing is awesome though. There's no guessing where you're gonna need to drill a big hole in your truck bed like the other brands. And this gives you the confidence and perfect placement for where to drill your holes up into the truck bed for the opening. We've done plenty of these underbed gooseneck hitch installs and sometimes even though you do things perfect with the measurements they give you, things just don't line up perfectly. And with this orange center locator, you don't need to worry about messing up your truck. The hitch is gonna come with the 2 5/16 ball. Pretty standard there. Overall, a good all-around hitch. To be honest with you, usually, I'm kind of partial to B&W hitches. They're really well made and I was pretty surprised at this one. CURT's definitely not bad by any means. Just when it comes to in bed hitches and things like that, B&W kind of shines in my opinion. But I was actually really surprised and impressed with this one. It went together really good. Didn't have to fight it really at all. Everything's well made and it feels like it's really secure and just a good fit for the truck. So, I feel like that's most important when it really comes down to it cause you're pulling some heavy stuff around. I definitely wouldn't hesitate to use it on my own truck. It's going to fit a lot of different trucks. Use our fit guide. Put in your year, make and model of your truck. And if it's a fit for your truck, I think you'll be happy. And that'll do it for your look at the line of CURT EZr Double Lock underbed gooseneck trailer hitches..

Installed as easy as they said it would. Videos are very helpful. Works great!



Still working great!


The hitch itself seems to be of good quality, well made, and there was no need to raise the bed of the pick up. Still, when it was delivered the box seams were open, the big parts were banging around, and the plastic bag containing all the small parts had broken open and the parts strewn about the interior. The ups guy and I picked up all the parts we could find on the driveway and thankfully I only had to make a couple of trips to the hardware store to buy what was lost. Had one of the custom pieces been lost, the 2 hour installation would have stretched into weeks. As it was, without a hoist and air tools it did take a couple of days. The video on this site was of immense help as the printed instructions were all too brief. I would suggest that the video incorporate wide shots periodically so the viewer can orient to the truck before going in for close ups.
Finding a 5/8" hole saw was no easy task either but I did find one eventually.
As always, its never as easy as it looks on TV.


The Curt EZr Double Lock Underbed Gooseneck Trailer Hitch (C619-648) is a solid hitch and worthy of praise. Had no issues installing on 2006 Silverado 2500HD and fits frame/bed perfectly.


Easy to install and works as expected.



Still works


I have not installed it yet but i have thoroughly have inspected it. Excellent product! Quick shipping






Seems heavy duty but the brackets hit the u-bolts and spring top plates. Curt told me I must of installed them wrong. I don't think so


Nice clean look. Most importantly didn't have to lower exhaust. centering the hitch in the bed was easy because of the template provided. Although install did take longer than what was noted, it was fairly simple. Would definitely purchase again.


I installed this hitch on my 2021 Silverado 2500HD. When first looking under the truck it appeared the exhaust would have to be modified to make the unit fit. The fact is this unit went in without any modifications at all…even all the factory drilled holes lined up perfectly. I recommend this hitch to anyone that has a stock exhaust system.


Great hitch and easy to use. I did have to lift up the bed a little bit to install it. Took me about 5 hours because of that but otherwise it is a great hitch. The rings for the safety chains stay on the bed and the ball flips over and stows away completely.


Easy to install. 64 years old and did it all by myself. So glad I went with this style. Have gooseneck and fifth wheel ability. When I want my full bed there’s no rails in the way. Pulling 13,000-14,000 lb fifth wheel camper. No problems.


shipping lost a box Men when box arrived 17 was destroed and missing parts. Need to do better job of packing for Shipping. Still waiting for missing parts.


2021 Sierra 2500 standard box. Item arrived pretty quick with all parts included and no damage.

Instructions for the install are, in my opinion, not very detailed and left me having to figure several things out on my own. Biggest pain was having to drop the fuel tank a few inches to access the hole in the driver-side frame rail to fish wire the one bolt for the side plate. Unsure why this info was missing as I would imagine anyone installing this on the same truck would have the same issue of not having enough clearance for the fish wire procedure. The front and rear rails are 0.25” in length different and are not labeled - be prepared to measure and appropriately install in the correct position with the holes closer to the bottom (this is poorly referenced in the instructions and leaves additional room for error and time). The install took me about 7 hours (no help).

Finished product is nice and sturdy. The ball ends up being about 4-5” forward the rear axle. I tried to find this info prior to purchasing, but could not. I use an extang hard tri-fold tonneau cover that does not flip fully up toward the cab and was concerned I would have to remove each time I hooked up a gooseneck. It appears that I will have to remove for most applications due to clearance issues, so less than ideal. Operates as intended and should bring many years of trouble free service.


Have not attempted install yet but looks well made and straight fowrard instructions


The instructions that come with are horrible. But you go on Curt’s website and they have a very well put together video. Everything went together smoothly and hitch performs great.

Box got a little hammered in delivery but didn’t damage any of the parts.


hitch itself fit good, Didn't really like the mounting design though. Kit requires one big bolt and a u bolt "Are supplied" that holds it on truck. Seems it could be made more secure with better designed mounting brackets,but overall kit fit well and is working for what i need.


Solid product, installation was fairly straight forward.


Build quality was outstanding, this is one stout piece of equipment. Install was a bit challenging because I did it by myself, but if I had someone to help it would have been much easier. Overall, the install was not too bad, just give yourself about 4-5 hrs if you don't have help. I'm very happy with this purchase and would definitely recommend.


Works as should except my handle on the ball broke to pull out of the bed when its hidden so i had to custom make a pull handle


Installed on a 2002 Ford f250 short bed. this was very easy to install just as specified I chose to remove my 5inch exhaust to make for more room and easier install but it went in smooth and the exhaust went back in with around 1 inch of room to spare so not much modification.
The only problem that I have ran into is for some odd reason when I hook up our gooseneck trailer the tongue weight brings the suspension down enough that the side plates actually hit the u-bolt studs that hold the leaf springs to the axle. So idk what’s going on with that but not real happy about it I’m going to have to cut my u-bolts down some in order for it to be able to ride smoothly otherwise the bracket hits the u-bolts every time you hit a bump and it doesn’t sound pleasant at all. Not sure if it’s just this hitch or other ones that do it but the side plates have an edge that sticks out and it’s slamming off of the U-bolts.


Easy install and very good customer ser vice


All I can say is WOW. In two days I received the Curt EZr Double Lock Underbed Gooseneck Trailer Hitch with Installation Kit. I plan on using this Gooseneck with an Anderson 5th Wheel hitch. I haven't installed it yet but I do plan on installing very soon as we have purchased a 5th wheel Travel Trailer. As soon as it is installed, I will post some pics. Again, I cannot believe it arrived in two days.
