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.

Accurate install directions, fantastic fit and operates perfectly for my 5th wheel RV



by:

After receiving the parts that were missing from the original order, the hitch was finally installed today, it took more then the 3 hours the video implied,
I haven't pulled with it yet, but looking forward to it..
The company was very courteous, very helpful, shipped the missing part promptly.
I will do business with them again.



by:

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.

Product is working great. Very pleased with my purchase and etrailer’s service.



by:

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.



by:

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.

1 year later and about 15k miles of towing the gooseneck trailer flawlessly. I would definitely recommend this hitch!



by:

Easy install, although since this is a dual pin lock on the hitch ball, there's no alternative hitch balls available that can work with offsetting or using a different 5th wheel hitch, such as the B&W Companion.



by:
2018 Chevrolet Silverado 2500

Solid product, installation was fairly straight forward.



by:

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



by:

Installation went well and the hitch works for everything we need

Fit great and easy to install. Took about Three hours to install with help inside the bed to hold center section up. The horses much prefer a ride in the trailer than walking twenty miles.

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.



by:

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



by:

Everything was easy and best quality. Glad I went with you guys!



by:

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.



by:

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.

  • Recommended Sliding 5th Wheel Hitch for a 2015 Chevy Silverado 2500
    A 16,000 lbs 5th wheel hitch would be perfect for your 2015 Chevy Silverado 2500. Since your truck has the gas engine you're no where near having an 18,000 lbs capacity so paying for a hitch that has one is unnecessary. Since you have the Curt Double Lock item # C611-624 and it sounds like you also have the Curt X5 5th-Wheel Base Rail Adapter Plate item # C16220, I recommend the Curt A16 5th Wheel Trailer Hitch w/ R16 Slider item # C16521. This 5th wheel hitch has a 16,000 lbs capacity...

  • Comparing Curt Double Lock and EZr Double Lock Gooseneck Hitch for 2017 Chevy Silverado 2500
    The only difference between the Curt Double Lock Gooseneck Hitch part # C607-604 and Curt EZr Double Lock Gooseneck Hitch part # C611-624 for a 2017 Chevrolet Silverado 2500 is the center locator tool that comes with the EZr. This helps to drill out the center hitch ball hole but aside from that they are pretty much the same. I recommend the EZr because of the added tool but if you are a more experienced installer, you can get away without it and save some money.

The Curt EZr Double Lock Underbed Gooseneck Trailer Hitch item # C611-624 has an identical towing capacity to the B&W at 30,000 lbs and installs in basically the same way. They both include a gooseneck ball,...

Both the # C607-604 and # C611-624 are a great fit that will for all intents and purposes work just as well as the other. For the most part the EZr is a smaller version that very similar but slightly different ball.

  • Curt Fifth Wheel Hitch Recommendation to Fit 2015 GMC Sierra 2500 with Curt Gooseneck
    Sounds like you have the Curt EZr gooseneck hitch part # C611-624 installed in your 2015 GMC Sierra 2500 short bed based on what you described. To install a slider gooseneck hitch you'll need an X5 adapter part # C16220 so that you have a set of rails for the hitch to install in. Once that's in place you could then install the Curt A16 5th Wheel Trailer Hitch w/ R16 Slider # C16521 that you referenced which would be a great choice.

  • Comparing Curt Double Lock and EZr Double Lock Gooseneck Hitches for a 2019 Chevy Silverado 2500
    The Curt Double Lock # C607-604 and EZr Double Lock # C611-624 for your 2019 Chevy Silverado 2500 are essentially the same gooseneck hitch. The only differences are that the Double Lock has a pin weight rating of 7,500 lbs while the EZr has a pin weight rating of 6,000 lbs and the EZr comes with a center locator to make drilling the gooseneck hole in your bed much easier. Both are rated for towing up to 30,000 lbs, have spring-loaded safety chain loops, the ability to store the hitch ball...

  • How to Tell Difference Between Curt EZr and Double Lock Gooseneck Hitch
    Easiest way to tell which gooseneck hitch you have is by looking at the safety cable loops. If they are about as wide as the gooseneck ball hole and are centered with the ball hole it's an EZr, if the safety chain loops are a smaller and offset then it's a double lock. Take a look at the pictures of the EZR part # C611-624 and the # C607-604 and compare your safety chain setup to both of these. Let me know which yours matches and we can go from there. The part # C16210 is for the Double...

    From a function point of view there isn't a huge difference between the two Curt gooseneck hitches that are listed as a fit for your 2016 Chevy Silverado 2500. That you would notice is the EZR has a smaller plate that has larger u-bolts for safety chains and the Double Lock has smaller safety chain loops that aren't centered.

  • Difference Between Curt Double Lock and EZr Double Lock Gooseneck Hitch for 2017 Silverado 2500
    Both gooseneck hitches are the same, but the # C611-624 (which is the C60680 kit) that includes the vehicle specific mounting rails also includes the center locater kit that makes drilling the hole in the bed for the gooseneck ball much easier. The C60710 which we sell as part # C607-604 doesn't included the center locater kit. The # C607-604 weighs right at 100 lbs, and the # C611-624 weighs in right at 110 lbs. Other than that, the hitches are identical. I've linked to some installation...

The Curt Double Lock has multiple slots for the safety chain u-bolts and the EZr does not so if you look under the hitch then you should be able to tell which you have.

  • Can Truck with Gooseneck Hitch Installed be Used for Transporting Cargo When Not Towing
    Yes, if you had a truck with a gooseneck hitch installed you would be fine to haul mulch, junk for the dump, etc. in the bed when you are not towing. For this situation I would recommend a removable gooseneck ball style hitch that has a cap that you can plug the ball hole with when not towing just to keep the hitch opening clean. I am not sure what vehicle you have, but the Curt hitch part # C611-624 is an example of a hitch that has a hitch ball like this.
