Video Transcript for Review of CURT Fifth Wheel Installation Kit - Universal Base Rails - C16204

Hello, everybody. This is Jeff at Today we're gonna take a look at the CURT Universal Carbide Black Finish Fifth Wheel Base Rails. Now, these base rails will install in your truck bed. And they provide the necessary attachment points for your fifth wheel hitch installation. Now, when these rails are used with the CURT's Custom Mounting Brackets, which we sell separate on a website, these rails will cut in half the time it takes to install your fifth wheel trailer hitch.

We mentioned the finish on this. I'm gonna zoom in and sort of show it. It's a carbide black finish, sort of like a matte black finish, so it matches the finish if you use it on the CURT Q5 20K Fifth Wheel Hitch. Now, these rails are universal, so they will work with the following fifth wheel hitches. They work with the CURT brand, the Draw-Tite, the Hidden Hitch, the Reese, and even the Husky.

This part here will include the two base rails. Now, we mentioned the mounting brackets, the custom mounting brackets, the hardware, and an installation kit is all sold separately. The length on these rails, if we put a tape measure on them from one end to the other, right at 43 inches long. But that should do it for the review on the CURT Universal Carbide Black Finish Fifth Wheel Base Rails.

Average Customer Rating:  4.6 out of 5 stars   (66 Customer Reviews)

When used with Curt's custom brackets, these rails will cut in half the time it takes to install your fifth wheel trailer hitch. They also function as replacement rails for your existing towing system.


I ordered C16418-204 which is rails hardware and brackets to truck frame. Within 3 business days I received the brackets but no hardware or rails and my tracking info showed delivered. So I started a case that I was missing the rails and hardware. I then ended up receiving the rails about 5 business days later but still no hardware so I emailed etrailer again and was in contact with Daylon from e trailer where I was told that kit doesn't come with hardware and that I would have to purchase it separately even though in the item description and pictures hardware is included I had to send multiple emails with screen shots of my order and confirmation email stating what I ordered and what I received Daylon final found the confusion and sent me the hardware although this whole process took about 3 weeks and ended up missing a camping trip that was already planned. Overall the rails and brackets are good quality just had poor customer service with etrailer and don't know if I will do business with them again


The product is just as described!! I would give it a 5 star review. As for etrailer if I could give a 0 I would. I bought a complete 5th wheel install kit that was suppose to have the rails. Rails were never sent with the rest of the install kit. Called and they said it would be another week before I would receive them. I had to pay and extra $[XX] to get the expedited shipping and then on top of that you charged me for the rails that you never sent the first time. Still waiting on my refund for rails. Your customer service is subpar at best! I do not recommend ETRAILER!


The delivery was not good half the hitch showed up with just the bed rails I called customer service they sent another package a week later with a second set of bed rails when I needed the frame plates then finally the following week the frame plates came with no instructions and I had to go out of my way to return the duplicate set of bed rails I have another hitch on the way I really hope this is a better experience not really impressed with this transaction


My order is apparently being shipped in two separate parcels. I received the custom fifth wheel installation kit but the rails were not included and apparently will not arrive until one week later. I can’t install one without the other so it would have been better to send the kit complete instead separating the parcels by a week. On a positive note I appreciated the emails advising the ship date with the tracking number.


I have not received the hitch as of this reply. I tried to track it but the last update was july 5th


It arrived very quickly and everything was packed nicely and everything came as desired


Fit and finish is very good. The rails have worked as described with out Anderson Ultimate hitch pulling around our 14,000 lb. 5th wheel.


I ordered the rails and brackets kit with included hardware for a Curt slider hitch. The order arrived 3 days later in perfect shape and the quality of the parts is 1st rate...heavy. Price was better than other stores. I'm happy.

Don S.


The hitch and mounting brackets work great except the slide is really hard to move with the 5er hooked up. Its very hard to pull the handle for the slide.


Great customer service. Item delivered on time Super happy


Great customer service.


Perfect fit


Good quality 5th wheel hitch ordered. Lucked out getting it on sale. Shipped on time. Arrived in perfect condition. Self install. Highly recommend Etrailer!


We bought a Curt slider hitch 16516 and base rails with bracket kit. Everything was very well constructed. We were very impressed with the product. We installed everything ourselves after watching the video. We highly recommend watching the video. Everything went together without any problems. Very solid hitch.


This was a fairly simple install.


Truck had holes and frame brackets for rails already from previous owner. Why they would remove rails I dunno, but I ordered up the Curt universal rails only and they bolted right up to existing holes and hardware. Cheap way to go!


Exactly what I expected from etrailer! Delivered earlier than scheduled. Great fit to my truck and existing equipment.


Perfect, they lined up with the holes in the deck and with my curt gooseneck


Followed the directions and it fit perfect. Good job.


Excellent customer service. Super fast handling and delivery. Karen C. did a great job of correcting a mistake that I made. I will use E-trailer again...Thank you..


Good product with great service and prompt delivery


all parts fit properly and are well made.because of tight clearances very hard to properly tighten rail bolts between frame and bed.4hr. install with two experienced techs. if on a lift would be less time.


The product seems to be well-made everything fits perfectly he trailer was very fast and they’re shipping


This company is always great to go to when you need something at a reasonable price usually delivered before they say it is coming great customer service and the parts are quality


The product was awesome fit perfect the people at etailer keep me informed on my order I was very pleased would highly recommend etrailer.
Thanks to all!!


The greatest parts and service departments YOU theBest.Thanks needed the parts today and got them.

  • Correct Base Rails for Curt E16 5th Wheel Hitch on 2021 Ford F-250
    In order to use the Curt E16 5th Wheel Trailer Hitch part # C16115 on a 2021 Ford F-250 you'll need the Curt Custom Fifth Wheel Installation Kit part # C79BR which is composed of the Curt Universal Fifth Wheel Base Rails part # C16204 and Curt Custom Fifth Wheel Bracket Kit for Ford part # C99BR. Please not, the base rails are not sold individually.

  • Above Bed 5TH Wheel Rails Availability Separate From Mounting Brackets
    We do carry the in bed 5th wheel rails separate from the lower brackets for your 2020 Ford F-250. I do recommend matching the manufacturer for lower brackets to ensure you do not have any fitment issues. Here is a list of the different rails we carry.

  • Do The Curt C16204 Universal Rails Come With Hardware?
    No, the Curt # C16204 Universal Rails do not come with hardware. The hardware will be included with the bracket kit, which is custom fitted for your vehicle. I see that you are looking for parts for a 2017 Chevy Silverado 1500 short bed. For that I suggest the B&W Custom Installation Kit w/ Base Rails # BWRVK2503. This is a full kit so you get your rails, brackets and hardware. I like the B&W kits because they are made in the USA, and the price is usually pretty competitive compared to...

  • Which Curt 5th Wheel Bracket Kit Fits A 2021 Ford F-250 Super Duty?
    I have another option for you, but the Curt 5th Wheel Bracket Kit # C16424 you were looking at only works with select Ford F-250/350/450s from 2011-2016. For your 2021 Ford F-250 Super Duty you will need the Curt # C16204 instead which comes with new above bed rails, as just the mounting brackets are not available. This will allow you to use a 5th wheel hitch that utilizes industry standard rails (ISR). Lastly since your truck does not have the OEM Towing Prep Package you may also be...

  • Curt 5th Wheel Brackets That Fit 2018 Ram 2500
    Hi Rick, We do have the correct Curt 5th wheel brackets that fit your 2018 Ram 2500, though it's a different part number than the one you mentioned. The correct brackets are the following: - Curt Custom 5th Wheel Bracket Kit for Ram Truck # C16427 Also keep in mind the # C16427 will only work with Curt base rails - part # C16104 or # C16204 - and will not work with any other manufacturer's base rails. And just in the interest of being thorough if you happen to need a 5th wheel wiring...

  • Curt Fifth Wheel Hitch Installation Kit for 2002 Ford F150
    The part you've asked about, # C16204 is the bed mounted fifth wheel base rails only. It does not include the frame mounting brackets or the installation hardware. For the complete kit that's compatible with your truck, you'd want # C16437-204.. The install rails are compatible with fifth wheel hitches that use industry standard rails, which includes Valley, Husky, Reese and Curt, among others. If your truck currently has a Gooseneck hitch with a 2-5/16 inch ball that sits in the truck...

  • Recommended 5th Wheel Installation Bracket/Bed Rail Kit for 2018 Ram 3500
    I'd recommend using the Curt # C16430-204 5th wheel install bracket/rail kit. This kit provides the industry standard 5th wheel mounting rails which are compatible with industry standard rail compatible 5th wheel hitches from Curt, Draw-Tite, Hidden Hitch, Reese, Valley, Husky and some B&W and Demco hitches, among others. If you'd like to install a 7-way trailer connector in the truck bed, you can do so using part # C56000. I'll link video showing how to complete the installation.

  • How Far Apart Do the Rails Need To Be To Install the Curt A16 5th Wheel Hitch
    In order to install the Curt A16 5th Wheel Trailer Hitch part # C16120 you'll need to position the base rails 22" apart on center. That is the distance between the center of the legs front to back. I have attached a photo with the dimensions of the above bed base rails that will fit the Curt A16. The correct base rails are the Curt Universal Fifth Wheel Base Rails part # C16204.

  • Fitment 2021 F-350 Dually
    The Curt # C16424-104 that you referenced is not a fit for a 2021. You will need the Curt # C16424 bracket kit and the Curt # C16204 Universal Base Rails. These 43" Rails are compatible with Curt, Draw-Tite, Hidden Hitch, Reese, Valley, and Husky. Their low profile takes very little room in your truck bed.

  • No-Drill 5th Wheel Brackets That Fit 2021 Chevy Silverado 2500
    We do have no-drill 5th wheel brackets which are a fit for your 2021 Chevy Silverado 2500. The correct fit for your truck is the following: - Curt Custom 5th Wheel Bracket Kit for Chevy/GMC Truck # C16429 This bracket kit will install onto your Chevy without any drilling, though they do require you use the Curt above-bed base rails (all 5th wheel brackets need to use the same manufacturer's base rails in order to fit). For that you can choose from two different finishes, either the Curt...

  • 5th Wheel Bed Rail/Install Bracket Kit for 2022 Chevy Silverado 2500
    For an industry standard 5th wheel bracket/rail install kit for your 2022 Chevy Silverado 2500, I'd recommend the # BWRVK2505 from B&W. The bed rails provided with this kit are industry standard, and fit industry standard compatible 5th wheel hitches from Curt, Reese, Draw-Tite, Valley, Husky, B&W and Demco, among others. The frame brackets utilize exisitng holes in the truck frame, but you will need to drill up through the bed in order to attach the bed rails to the frame brackets. If...

  • Can You Mix Fifth Wheel Rail and Bracket Manufacturers
    We can't recommend the mixing of fifth wheel brackets and rail manufacturers. If you have Reese rails you would want a set of Reese brackets. Without knowing what vehicle you have it would be hard for me to recommend the correct brackets to go with your rails. If you have Curt brackets and need rails you would want # C16204.

  • What Is The Difference Between The Curt C66HR And C22ER 30k Hitches?
    Though I do need to start by saying the highest rated fifth wheel hitch available for a 2019 Ram 3500 long bed with the factory puck system will be the Reese M5 5th Wheel Trailer Hitch # RP37FR, which is rated to 27,000 pounds, I can still compare the Curt 30k hitches for you. First, the Curt A30 # C66HR. The A-Series fifth wheel hitches have been around for quite some time and the second is the Curt PowerRide # C22ER. This is Curt's brand new fifth wheel hitch.

  • What 5th Wheel Hitch is Compatible With Industry Standard Base Rails?
    The Curt Universal Fifth Wheel Base Rails - Carbide Black Finish # C16204 are industry standard base rails just like the Reese # RP58058. These allows any fifth wheel hitch that is designed to fit Industry Standard Rails to fit your truck, which is most of the hitches on the market. I recommend the Reese M5 5th Wheel Hitch # RP30928 because it is a top of the line hitch with safety features such as the easy-to-see king pin indicator and wraparound king pin jaw as well as features that...

    Although we don't offer a Husky 5th wheel install rail and bracket kit for your truck, we do offer a reasonably priced bracket/rail kit that would be compatible with your Husky 5th wheel hitch. I'd recommend you go with the Curt # C16411-204 Custom 5th Wheel Install Kit. The kit uses existing holes in the frame, so the only holes you'll need to drill are the ones down through the bed to attach the rails to the brackets which bolt to the frame.

This applies to both short and long bed trucks.
