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.

I think this gooseneck hitch is the best for newer Sierra/Silverado HD trucks. I installed it a week ago with the help of my father-in-law and his car lift. Took about 4 hours moving slowly and taking our time. Everything fit well and bolted right up. I also reinstalled the foil heat shield after removing one mounting ear. I did not drop the exhaust or the plastic heat shield and still got everything in.

I chose this specific kit because it did not require notching the bed seam when installing the rails. It also has a higher tongue load rating than the others and was cheaper.

The only major criticism I have is the pull wire and carriage bolts. My chassis has weld nuts and I would have preferred to use those over carriage bolts pulled into the chassis. I am thankful there were access holes almost inline with the mounting holes. That made it easy to put pressure on the bolt heads so they didn’t fall back. I also think the gasket around the big hole should be one piece to make it look cleaner. I used black silicone rtv to smooth the transition and adhere the gasket in place.

Overall I am completely satisfied with the kit and the help of Shawn B who got my order in, had it shipped that same day and followed up with me after delivery. Thanks etrailer and Shawn B.

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.

I did the install myself on a 2019 GMC 2500 Short bed. I watched several videos before. I did not remove either mud shield or cut out/remove the heat shield. I chose not to install the chain holders since my Andersen Hitch has it's own tiedown bracket. My bed has a spray liner and therefore the edge covering would not fit the newly cut edges around the hole opening. So be sure to paint the exposed metal. In one of thg he videos a tech use a predrilled board as a guide during the drilling of the bed hole. This was a great idea. Since I chose to keep the heat shield installed I had to lift the main unit into place by sliding it up between the gas tank and rear differential unit. I think it would have been very helpful to have a tools required list before I started. Also, the tip about cleaning out the powdercoated threads was very good idea. Preptime, tapping threads, install and cleanup (tool put away) was over 6hrs....and I skipped a lot of disassembling a n.v d reassemble steps. Everything was straight forward and understandable. A lift would have been great but I used rear ramps which was enough. Make sure you get a step ladder for bed entry now. I expect it to work as expected. Seems very solid!

Wonderful customer service parts arrived as promised. The box was damaged doing ship but everything was still there. Very easy installation. The front rail and goose neck plate have a indention to clear fuel tank. The indention still rubs the fuel tank, I had to pry up on the rails before tightening the side mounts. Other then that everything else was pretty smooth.

Easy to install just follow the video on website. I did it by myself. Took about 2 hours. Thanks.

After one year the hitch is still working great. I tow my tractor all the time with no issues.



by: Tony05/20/2019

Install was straight forward on 2017 silverado 3500hd. I chose this kit because I don't have to trim any part of the bed to slide the cross rails in. Watching the video helps prepare you a head of time of what you need and to expect. Shipment was quick and undamaged.



by: Luis09/03/2019

Perfect fit, really snug and tight. Good to have a jack laying around to lift the gooseneck into the right spot to fit bolts into their spots. Towed a 15k trailer to Texas with no complaints. Great gooseneck so far



by: Raymond05/24/2023

Product is very good I’ve installed several of these hitches but this time the packaging was terrible. The crossmember bars were hanging out of the box the bolt packages were opened and I was missing bolt hardware to install the hitch. The wires used to pull the bolts through the frame one of them looked like it had been used and was all deformed to the point I couldn’t use it. Not sure if this was a restock hitch or what put all the packaging was terrible and missing parts.



by: Taylor 11/27/2023

I’ve had this hitch for about a year, and it’s great! It does exactly as it should. The only complaint is the red grip on the pull handle was basically sun faded and rotted after about 2 months.



by: Steve 12/27/2019

Hitch was as promised. Installed by myself and fit perfect in a 2018 2500 HD Chevy. I lost a u-bolt spring during installation and CURT replaced it free of charge. etrailer employees were great and hitch was delivered quick. I highly recommend etrailer, CURT and this hitch.

Very easy to install on my truck. I use it weekly to pull my trailer.



by: Will01/06/2022
2016 Chevrolet Silverado 2500

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



by: Ann12/07/2020

This is the second hitch I’ve ordered from etrailer. This first one back in 2007 I had a GM dealer install. This recent one I installed all by myself! Very easy and straight forward instructions. Hardest part is the contortions you have to get yourself into. I did have a bit of an issue getting the plate itself over the gas tank. Video suggests lowering the tail pipe. Instead I just took out the bolt on the rear cross rail drivers side and loosened the passenger side. Swung the cross rail back, slipped the plate in and reinstalled the rear cross rail. Oh and the shipping was fast! Very, very pleased.

The video was extremely helpful. All holes lined up and installation went smoothly.



by: Eliseo05/29/2020

Instructions made this install easy for me. I am very capable and had no problems. Have hauled 14 foot dump trailer with sand or gravel and performance was excellent.

Has worked out fine. Tab for lifting out ball from storage broke off but does not effect performance. Also tore apart the rubber cover while loading a bundle of plywood on my truck. Again no effect on performance.



by: James04/05/2022

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.



by: Mitchell D03/23/2020

Still works great install was pretty straight forward and it’s a pretty clean unit (looks nice). My only complaint is the cover in the handle wore off in less then a year so it’s bare metal now.

Mitchell D.

4/4/2021

Love the ball my own complaint is the rubber cover on the handle wore off very quickly. Still functions great otherwise.



by: Bob10/19/2023

I really like the product now that it is installed and operational. I had some difficulty getting all the holes to line up as tolerances were tight.



by: Phil09/14/2022

The picture enclosed show how package was received from UPS. Hardware was falling out of box and steel parts laying at bottom. Plastic bag that contained hardware had been torn open. It appears to be a customer return that was not probably repackaged. There are luckily only some washers missing. Customer service was very nice and apologized saying they would replace hitch but time doesn’t allow for that



by: Rsroosa12/18/2020

Great hitch Installation was relatively easy. Great price compared to some others. Highly recommend

Still Awesome, No problems.



by: Kevin06/08/2021

Hitch has a lot of slop in the receiver in bed you can hear it pop when you take off and pop sometimes when you stop . I don’t know if I got a bad one that has more tolerance or not but would not recommend if there are others with the same problem going on .



by: Norvin M07/09/2016
2016 Chevrolet Silverado-2500

Very satisfied with hitch . Installation was
Easy , except drill template was made improperly and extra measurements were required prior to drilling 4" ball hole.
Also would suggest that Curt should clean paint out of all threaded holes prior to shipping.

Norvin M.

Great, have bought and installed one in my 2017, design improvements for drill template and frame flange mounting are great

It was good install and has been great. took a while to get here but I'm happy I went with the curt and with etrailer

Do you have a question about this Gooseneck Hitch?


  • 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 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.

by: Anita03/02/2024

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: Jimmy 03/17/2021

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: James G.05/17/2017

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: Steven 08/03/2021

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.

Solid product, installation was fairly straight forward.



by: Andy S04/15/2019

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: Derek 12/02/2022

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: Scott06/25/2020

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: Tom03/04/2022

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: Steven R04/24/2020

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.

Seems to be very well built. Shipping was very fast. Will definitely purchase other products.
