This hitch is made to pull serious weight—up to 30,000 lbs gross towing weight and 7,500 lbs vertical load. It’s a heavy-duty underbed design that gives you the strength and stability you need for big livestock trailers, dump trailers, or long fifth-wheel conversions. The double-lock system uses two locking pins instead of one for a stronger hold on the ball, adding that extra level of security when hauling heavy gear down the road.
When you’re done hauling, you don’t have to live with a hitch taking up space. The chrome-plated 2-5/16" ball flips right over and stores inside the hitch for full use of your bed. Drop it in upside down and lock it with the handle—no tools, no fuss. A rubber cover caps off the hole to keep out dirt and grime, leaving a clean look and open bed so you can load up pallets or gear without anything in the way.
The comfort-grip handle mounts inside the wheel well so you can reach it easily to lock or release the hitch from the side of the truck. Once the ball drops into place, rotate the handle to let both locking pins snap in for a tight, secure connection. The chrome ring around the ball hole gives it a finished look, while built-in safety-chain hookups keep everything tidy and ready to tow.
Everything you need for installation is in the box—custom mounting kit, rails, and Grade 8 hardware. You’ll just need to cut one 4" hole in the bed for the hitch ball; no welding required. The steel frame is black powder coated for durability, zinc plated for corrosion resistance, and backed by a 7-year limited warranty so you can count on it season after season.

Great hitch, great price.
Worked great. Easy to install.
easy insall
Had a part missing in the shipment - very responsive to get this fixed. Great customer support.
I purchased a gooseneck assembly for my 2018 Silverado and received half the stuff that was suppose to come with it and so I called and was suppose to get the stuff I’m missing and after getting the next package I’m still missing parts that never got sent
you did a great job. freight on the other hand was terrible both boxes broke open and torn. they tried to tape them up. from what I can tell looks like everything is in the boxes.
The springs for the safety loops are to small in diameter. The washers slide over the springs.
The hitch fits perfect and was shipped the next day from ordering it.
Took a while to install, but it holds up nice. Had it for a year now- hauled a horse trailer jam packed many miles over the year and absolutely no complaints so far.
Great fast shipping great customer service like everyone else said their packaging is not great but if you are missing anything they get it out instant I appreciate them for sure I would recommend for sure thanks
Great product, install went great. Luckily I’ve put in multiple of these units and knew how to install it cause the directions in the kit are very minimal. Other then that I’d recommend this kit to anyone. Also if you have air bags installed onto your truck like I do you will need to do a little fabricating to the bracket to make it work.
Kit was missing pieces and neither the company that sold it or the company that owns the brand would make it right

I'm very sorry about that Dakota, we're working with Curt to get those missing parts sent to you. I'll reach out soon with an update.
We had problems getting all the parts , it took a lot of e- mails to finally have everything . The problem was mostly from Curt not etrailer . We also have to consider it was during the Covid period . Otherwise I would rate excellent
Customer service I would give 1 star-Never received the first hitch I ordered as it was lost. Customer service told me I would have to wait until UPS finished its investigation before they could reorder and re ship the hitch to me and wanted me to pay again for a new order before they would ship. Only until I told them to cancel and refund my money did they ship a new hitch to me.
Definitely a quality hitch! Very fast shipping! Hitch was a little more difficult to install than I expected but I'm also just a backyard mechanic. Got it installed in several hours with several breaks. I'm very happy with the outcome and use it to pull a small 5th wheel.
Hitch has just been installed. Hitch comes in two cardboard boxes, very poor as components are way to heavy. Longer heavier box was torn open and plastic centering ring to locate four inch hole was gone and small parts were all over in box. Make sure you run a one half inch die into and through all of the holes in the two cross bars. In my case I had to remove and revamp the air bag top supports. Quite a lot of extra work but, they are now reinstalled along with the hitch. Cutting the four inch hole with a hole saw was quite a challenge as the bit would catch the box sheet metal and I could not hold it. As I have had Curt products in the past, I assume this hitch will work for many years.
Could be packaged better. The parts are heavy and rub on each other and in some cases the finish was scraped off. Had to chase the holes with a 1/2" tap, because the finish on the hitch was sprayed into the holes. Directions were ok. Hitch fits fine and works well on my 1/2 ton Chevy. The person I worked with at etrailer.com was helpful and the hitch was shipped promptly.
I really like the hitch as it was easy to install and being a turnover ball it leaves my bed free when I need to haul something. Very sturdy product and I would recommend it to anyone looking for this style of gooseneck hitch.
I installed this by myself in about 3 1\2 hours.
Very good fit.
Love the Curt C615-632 under bed kit. It maximizes the use of the bed of my truck, and has a clean 4" cap when not towing
I am very satisfied with y’all products and the quality of the hitch. I installed it myself with no issues Thanks
