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.

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.

One year later and my hitch is still excellent! The red grip looks exactly the same but not much else has changed.

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.



by:

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.

2016 GMC Sierra 2500

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.

2019 GMC Sierra 2500

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!



by:
2013 GMC Sierra

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.



by:

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:
2017 Chevrolet Silverado

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.

2015 GMC Sierra 3500

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:
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:

I've had my gooseneck ball hitch for about a year now and I absolutely love it. I use it alot and I love that I can flip the ball over for storage when I'm not using it so I have full use of my truck bed. It is very easy to install, I did it myself self in a few hours. Overall a great product and would definitely recommend to others.

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:

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.



by:

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:
Chevrolet Silverado

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.

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



by:

Have had this hitch in a 2004 F250 and had no issues with it. That’s why I purchased this hitch to go in my 2016 Chevy 2500HD only reason I didn’t give five stars is the box was damaged severely and the hardware bag was torn and all the hardware was loose in the box and falling out when the delivery driver brought it. Luckily all hard ware was accounted for.



by:

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 .

  • 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.

  • Recommended 5th Wheel Hitch for a Curt Underbed Gooseneck Hitch
    B&W does not but I have something that is comparable. B&W's Turnoverball systems and their Companion hitches work exclusively with each other and are not compatible with other gooseneck hitches like your Curt item # C611-624 or item # C607-604. They have a square receiver over a circular one. To connect a 5th wheel hitch to the Curt gooseneck ball in your 2016 Chevy Silverado 2500, I recommend the Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter item # DM8550045. This 5th wheel...

What makes the B&W the best option, and separates it from the likes of the Curt Double Lock # C607-604 which also fits your '19 Silverado 3500, is that the hitch ball of the B&W gooseneck hitch has a square shank that fits directly in the base, and is...

    I went ahead and checked with my contact at curt to get some clarity on this one. There is no 4-5/8" hole saw required to install this # C607-604. You would use a 4" hole saw for the center hole, and you would use a 5/8" hole saw (or drill bit) to make the holes for the safety chain loops. The way they have it worded in the instructions is certainly confusing (4" and 5/8" hole saw).
