This heavy-duty 5th-wheel hitch is rated for 25,000 lbs gross towing weight and a 6,250 lbs vertical load limit, giving you the solid connection needed for serious towing setups. The sturdy steel construction with a durable carbide powder coat finish provides lasting strength for repeated use. It’s a hitch that stays locked-in and stable even when you’re hauling across rough roads or steep grades.
The interlocking dual-jaw design wraps completely around the king pin for full 360-degree contact. That means less rattle and more security compared to slide-bar models. The result is a quieter, smoother ride where you can feel the hitch holding steady—no clunking or shifting when you accelerate or brake. It’s built to give you confidence every time you hook up.
The built-in color-coded lock indicators make it easy to see what’s happening at the hitch. Red shows it’s uncoupled, yellow means ready to couple, and green confirms it’s locked for towing. You can check your hitch status at a glance from the handle or the hitch itself, so there’s no guessing before you hit the road. The handle also self-resets to the ready-to-couple position after you unhook, saving time when setting up again.
The S25 slider gives you 12 inches of fore/aft travel to create the clearance needed for tight turns at slow speeds. It slides easily and automatically latches in both directions, so you can focus on maneuvering instead of fighting the mechanism. When space is limited, this feature helps prevent the trailer from contacting the cab during sharp turns while keeping the setup stable and predictable.
When it’s time to clear out your truck bed or perform maintenance, the fast 1-pin head removal design lets one person take off the hitch head without tools. Two built-in zerk fittings simplify lubrication, keeping operation smooth over time. The included plastic lube plate helps the king pin glide easily into position during hookup, making every connection cleaner and more consistent.

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at the CURT Custom Fifth Wheel Bracket Kit for the Chevrolet and GMC trucks. Now, this is a custom fit part. It is designed to fit the 1999 to 2010 Chevrolet Silverado and GMC Sierra 1500, 2500 and 3500 models, with either the six and a half foot bed or the eight foot bed. And on a custom fit part like this, I do like to recommend for you to go to our website, use the fit guide, put in your year and model vehicle. That'll show you if this will work for your application.
Now these brackets right here, they are designed to mount beneath your truck bed to provide the attachment point for your fifth wheel rails. Now those fifth wheel rails, we do sell separately on our website. They go by part number C16104 or C16204. And just give you an idea what those rails look like, they come in a set of two, and again, they'll attach to these mounting brackets on your vehicle. This provides a custom fit by mounting to the existing holes in your vehicle's frame.
That will minimize the amount of drilling that's required to install these, and it'll cut the installation time in half when compared with universal bracket kits. If you notice, it does include all the necessary hardware to install it. It does even come with this nice extra bracket for relocation of the electrical box. And it comes with a nice set of instructions with pictures that'll describe how these parts install. The finish on these brackets is a nice black powder coat finish to resist corrosion.
And these will work with the BMW, CURT, Draw-Tite, and Husky above bed fifth wheel trailer hitches. But that should do it for the review on the CURT Custom Fifth Wheel Bracket Kit for the Chevrolet and GMC trucks..
Ratings & Reviews
The installation kit had everything I needed & fit perfectly as it should have. I would have given a five star rating but neither the instructions nor the video mentioned lowering the gas tank which was neccessary on my 2009 Chevy dually with the 35 gal tank. Aside from that the install went smoothly. I would have no problem recommending this kit & etrailer to anyone
This is the 4th hitch I have installed over the years so I'm not a novice. I thought I would order the custom kit for ease of installation. Was I wrong. followed the instructions to the letter. I ended up taking my truck to the dealership to drop the fuel tank to reach the front drivers side nut for the front rail. Also on the frame about midway it's double thickness. Tried using the wire provided to "fish" the front bolt in.. Was only enough room to barely get the wire in much less the bolt.. Bought a tap for $45.00 a threaded the frame instead. Over all I should have taken my old system out and put it in this truck. The nuts were welded to the frame and you just insert the bolts and tighten.
A must have kit for installing a 5th wheel hitch in your late model Chevy. All the components fit, instructions are easy to follow. It's not an easy install due to components on the truck and access issues, but this kit takes all of the guess work out of it. Do yourself a favor, buy a cheap 3/4" wrench, cut it in half, weld in a piece of 1/4" x 1" flat bar to make a 24" long 3/4" wrench. You'll thank me for being able to tighten bed rail bolts between the bed and fuel tank, and in between the bed and exhaust heat shield.
The install went easily and smoothly, made for a near perfect fit. It didn't last me a year though, got it from Maine to Florida, but the spring trip north only made it as far as Richmond Hill Ga where I rolled the truck & trailer. Nobody was hurt, and the Curt system (with my Reese 5th wheel) held up so well, that the police had difficulty separating the truck from the trailer after the accident. Good product (and this was the 2nd one I've installed over the last 5 years.
This kit is perfect! Comes with everything you need with easy to install instructions. I’d recommend this and other etrailer products. They match all factory specs. Simple and easy
Instructions were very easy to follow, diagrams were detailed and clear. The installation itself is a bit of a chore but with simple hand tools and a helper to hold the carriage bolts inside the bed, the install took less than 90 minutes.
I’m able to do so much more with my truck now that I’ve installed these rails. I’m pulling fifth wheels and goose neck trailers. I had to drill a hole in each side of the frame which wasn’t the easiest thing to do. Use a jack and a block of wood to lift up on the frame but leave the tires on the ground. This will give you more room for a drill and an impact gun to tighten everything up once it’s on.
The Help & professionalism of Quinn F @ etrailer.com was outstanding. He confirmed that the product was the best choice for my vehicle & purpose, his personal response & follow through impressed me (including an e-mail letting me know my parts were delivered a couple days early). I will definitely be using Quinn F @ etrailer.com for all my RV related needs.
The rails and mounting kit arrived on time and intact. This is the second time I have ordered thru etrailer and I will again if I need anymore trailer hitch products
Worked very well. Instalation instructions were precise and easy to follow. Took some work to install which was worth the effort.
I just received the hitch. I ordered it very late New Years night. It shipped the next day with an estimated delivery of Friday before 8pm. I received it on Thursday about noon. Awesome super-fast shipping. It came in 3 HEAVY boxes, one of which was slightly damaged but I have not unpacked it yet. I hope to do so this weekend. I have bought from etrailer before and have no doubt this will be as good as the other purchases I have made.
I wish I could give two ratings for this kit, one for quality of product, and one for quality of fit and instruction. The product quality, once it is installed is very nice and heavy duty.
The instructions, and the fit on my 2005 GMC one ton dually leave a lot to be desired. They say it should take about 90 minutes to install. Plan on about 8 hours if you don't have a lift, and plan on drilling 3/4 inch holes in the frame rails. You better have access to a compressor, cut off wheel, 1/2 inch impact gun, 1/2 inch drill motor and 3/4 drill or reamer. This is NOT for the average "weekend warrior" with a small set of hand tools to install.
Very strong product I would give five stars except the instructions would not be good for an every day truck owner but the E trailer video is really good the only issue with a long bed is you have to drill 4 holes in the front of the frame two on each side and be aware if you do have a long bed truck you will need a big drillbit for instants I used a 7/8 but the overall product is good shipping was great could not imagine having to install the universal brackets and this kit made it so much easier
Product was great but what I really want to review was the customer service one of the packages showed up box was broke open and parts missing Lauren in customer service got right on it and had new parts to me within a couple days ..A+ effort and communication
Installation is a breeze
I order the items I need and they were immediately placed for delivery. I received hitch and slide quickly. Packages were shipped with care. Excellent instructions.
Well built. Some bolts are a bugger to get tightened up but not bad. Didn't remove the heat shield.
Nice well made with thick material. Time would tell how sturdy it is. Easy to install, clear instructions with everything you need for it. (Nuts and bolts).
This is my second mounting kit that I get for my trucks.
Installed on my 2005 Chevrolet 2500. Used install videos from your website and had no problems at all installing. Fast shipping also. Thank you for a great website!
High quality, heavy duty system. Bolted right in and instructions were easy to follow. I feel good about pulling our camper with this set up. Only issue was shipping, the box was damaged and was missing the pins that were ordered. But customer service quickly got thing fixed and resent.
The Curt A25 5th Wheel Trailer Hitch with S25 slider worked perfectly on my 2024 GMC Sierra 2500HD Denali. Install was a breeze. Great pricing as well at etrailer.com.
This is a great kit from Curt to install your 5th wheel hitch. Installation was not to hard even while working on the ground. Tightening up the frame and rail nuts was a little difficult. You will need an Extra Long 3/4 inch Ratcheting Wrench to get to the ones near the fuel tank. The customer service from etrailer is Exceptional. I was missing a few spacers and bolts because UPS trashed the box but etrailer replaced all the hardware over night. Definitely will be using this company for all future purchases. Thank you!
Upon delivery the box was a little banged up. Everything was inside was still in good condition. To my time with install to insure proper alignment, the only thing I can say negative about it is, you need 4 additional 3/4 inch washers for the frame bracket bolts that are not included, at least I did! On both sides. In the end it was a rather easy success.
2004 Chevy Silverado 2500HD, installed the Custom 5th Wheel Installation kit along with the Q16 Slider Hitch. Product arrived very quickly after ordering. It was shipped in 3 different boxes. One box was a little beat up during shipping, but all of the parts were there and undamaged. I watched the installation video once, then my brother-in-law and I tackled the job which took us about 2 hours. This was not difficult to install other than trying to get the 1/2" bolt through the hole on the driver side of the frame (the frame is boxed there). The included wire guide helped, but you still have to manipulate the bolt into the right position in a very tight spot. Everything turned out to be a perfect fit, no modifications needed. Also, I removed both rear wheels before starting which gave us plenty of working room. I have purchased from etrailer in the past and will continue to use them in the future.
Items as described arrived on time and installed rather easily, directions were very good and the installation video helps a lot
