Video Transcript for Review of CURT Fifth Wheel Installation Kit - Custom Brackets with Base Rails - C16418-204

Hello everybody, this is Jeff at Today we're gonna take a look at the CURT Custom Fifth Wheel Installation Kit for the Chevrolet and GMC trucks. This one has the carbide finish base rails on it. 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, and it'll show if you this will work for application.

Now this kit here is a complete installation kit. This will allow you to install a fifth wheel to your truck bed. This kit here includes the custom fit mounting brackets right on your side here. The base rails, the hardware to install everything, comes with a nice set of instructions that'll have pictures of how everything goes together. And they even include this extra bracket for the relocation of your electrical box.

Now the brackets on the side here, these mounting brackets, these will mount beneath your truck bed and they provide the attachment points for your fifth wheel rails. This provides a nice custom fit by mounting to the existing holes that's in your vehicle's frame. This will minimize the amount of drilling that's required and it helps cut the insulation time in half when compared with the universal bracket kits that are out there. Now the base rails, which is these here, these base rails is what'll sit in your truck bed and they allow the installation of your fifth wheel trailer hitch to your truck. These base rails are visible, and these have the nice carbide mat finish to them which will match the CURT fifth wheel hitch.

These mounting brackets have a nice black powder coat finish to them to resist corrosion. And this kit is designed to work with the BMW brand, the CURT, the Draw-Tite, the Hidden Hitch, the Reese, and even the Husky brand above bed fifth wheel trailer hitches. But that should do it for the review on this CURT Custom Fifth Wheel Installation Kit for Chevrolet and GMC trucks. And this has the carbide finish base rails..

Install your fifth wheel trailer hitch in half the time with this custom bracket kit. Requires less drilling than universal kits and provides a custom fit for your vehicle. Includes everything you need for installation.


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.

2005 Chevrolet Silverado

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.


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.

I emailed you a picture of the parts list, which items are you missing?

There were no parts missing! Just 4 extra 34 inch washers were needed

2005 Chevrolet Silverado

Well built. Some bolts are a bugger to get tightened up but not bad. Didn't remove the heat shield.

2004 Chevrolet Silverado

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.


Easy install,great product


The Help & professionalism of Quinn F @ 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 @ for all my RV related needs.


All I needed


Just got everything delivered today. Looking forward to installing it. More to follow

Very satisfied with the 5th wheel hitch and the kit I received to install onto my 2002 GMC Sierra. The online videos really helped I will recommend this set up to anyone I know who is considering a 5th wheel tow package
Brian - 02/17/2023


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

Update I have probably put about 5000 miles of towing With this kit I have not had an issue with it still looks good no rust all the bolts are still tight

2005 GMC Sierra

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 heavy duty. Very secure. No problems aside from the initial installation. Nice setup.
Jeff M - 06/23/2015


My order arrived quickly, as promised. It was an easy process of ordering it. I reserve 1 star on my rating as I have not opened the box and installed it yet. I'm hoping - all the pieces are present and the installation goes easy?

2005 Chevrolet Silverado

The curt custom kit was very well made I have a 2005 chevy 3500 Dully long bed A couple of things that you will have to do when installing the kit you will have to drill two holes in your frame for the installation of the frame brackets on the front a 1/2 inch hole and 7/8 hole you will have to remove your spare tire you will not have to drop your gas tank or cut your exhaust heat shield out of the way but the only thing you will have to do is cut a quarter inch off of the large bolt on the driver side front three-quarter inch bolt because it will not fit in The frame area properly without doing that other than that the install was great and very well-made it Took me 3.5 hrs to install and my hands are beat up good luck and safe travel


Just received this and haven't installed it yet. I plan to add it to my truck in about 2 weeks. This is exactly the same as my last truck which was a perfect fit. It also worked great pulling my 35-foot fifth wheel RV. I look forward to the same quality as before, perfection.

Checked the install to make sure everything was still good. No problem found even after a year.

2008 Ram 2500

Another success from etrailer! Ordered a 5th wheel rails kit for my Chevy 2500 Duramax. It arrived within a couple of days as scheduled. Even though I didn't install it myself, the install fit my truck well and looks very clean. I didn't get any nasty calls from my installer so I am guessing there weren't any issues. Lol. I will continue using etrailer as my go to place for quality parts that fit well at a good price!

2006 Chevrolet Silverado

Installation was simple enough with the guide. Measurements were spot on and bolted through the bed correctly. The frame rails are a different story...the front holes shown in video were for a short bed. On the long bed version, the two front holes have to drilled on each side. Make sure to tighten the bolts in the bed first to ensure alignment. The driver side frame rail doesn’t allow for the fish wire for the larger of the two bolts, because the fuel tank support straps are directly behind and Chevy made this section of the frame narrower. The bolt must be installed from the outside with a small person, daughter-in-law, holding the nut inside the frame and tighten from the outside. The passenger side, no problems at all. Once those four holes are drilled everything else is a cake walk. May be different on other models than Chevy, but would have been nice to know before and to have a large enough drill bit on hand. If not for the extra drilling and frustration this would have received a 5 star.

2001 Chevrolet Silverado

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.

1 Year later, the brackets and rails still look new. the paint hasnt chipped or faded. I interchange a 5th wheel saddle and gooseneck ball plate often and even the paint near the mounting points still looks good.
Josh J - 07/16/2020


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 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


Great product. Worked very well


Every thing was satisfactory except the tracking system was terrible bad link or something you need to look into that. Sorry no photos yet not installed


fast shipping, good price, excellent co mapany


Parts fit as advertised. Great service , quick shipping and quality products.


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.

My son and I installed this hitch without a lot of problems. It arrived complete with all parts intact. It took us about 2 hours of leisure effort to get everything installed. The only thing we could not do was torque the larger frame bolts since I do not have a torque wrench that goes that high. One call to a truck shop got that settled for much less than it would cost for a new wrench.Everything else went together easily.
Jim H - 01/04/2019


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

After a year I still feel the same. A great product and a good price
