Video Transcript for Review of CURT Fifth Wheel Installation Kit - Custom Fit - C16420-204

Hello everybody, this is Jeff at Today we're gonna take a look at this CURT Custom Fit Fifth Wheel Installation Kit with the carbide black base rails for the Dodge trucks. Now this is a custom fit part. It is designed to fit the 2006 to 2008 Dodge Ram 1500 extended crew cab trucks. Also the 2003 to 2012 Dodge Ram and Ram 2500 and 3500 trucks. And because this is a custom fit part, 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 this will work for application. Now this kit is a complete installation kit to allow you install a fifth wheel to your truck bed.

The kit will include everything shown here on the table. It includes the side custom fit mounting brackets here, the base rails, includes all the hardware you need for installation, even a nice set of detailed instructions that'll describe how it all goes together. Now those custom brackets on the side here, I wanted to zoom in on those. These custom fit brackets are designed to mount beneath your truck bed, and they provide the attachment points as you can see here, for your fifth wheel base rails. These parts have a black powder coat finish on 'em to resist corrosion.

And we mentioned they provide a custom fit by mounting to existing holes in your vehicle's frame. If you see these holes that are already in there, these will line up with holes in your frame, so it minimizes the amount of drilling that's required, which in turn will cut the installation time in half, when compared with the universal bracket kits. Now these base rails right here, these are what'll sit in your truck bed. They allow the installation of the fifth wheel trailer hitch to your vehicle, and these rails are visible in your truck bed. And if you notice, these have a nice carbide black finish to 'em, sort of like a matt black finish.

And that's to match the color of your fifth wheel hitch. These are industry standard rails that are compatible with B&W, CURT, Draw-Tite, Reese and Husky Above Bed Fifth Wheel Trailer Hitches. But that should do it for the review on these CURT Custom Fit Fifth Wheel installation kit with the carbide black base rails for the Dodge Trucks.

2012 Ram 3500

2012 ram 3500 mega cab short bed! Well from all the reviews I’ve read, and the video, I gathered about 5-6 hours to install by myself, which was very accurate, directions say 90 min instal, not! It was the 5-6 hour range, regardless it went in as the directions and video said! Take your time measure it out double check everything, the kit is great, follow directions and watch the video you can do it in your driveway!

2011 Dodge Ram Pickup




I still have no complaints I have pulled my 35ft fifth wheel camper multiple times already and it did great. I have since recommended etrailer site to everybody I know that needs hitches. Thank you again for making it so easy to order and install!

2011 Dodge Ram Pickup

This is a well put together package. The fact that you do not have to drill the frame makes things much easier. That said, it is still a lot of work and if you do not have all the tools needed and a lift you will be at this install for quiet some time.

The spare tire has to be removed and if there is a spare tire shield it will have to go as well. The inner fenders need to come out and at that point you will find it is easier if the tires and wheels are out of the way. It is a bit of work to get the right rear bracket in with the tail pipe in place. Also the spacers that go into the frame are also hard to get in place. Lastly, you will still have to drill holes in the bed.

With all this work required, I am very glad that I did not have to drill the frame also.

2012 Ram 2500

Fish wire was too short for long bed installation. Instructions did not address how to clear my brake lines on the left side front bracket. Overall the installation was not as easy as the video depicts. I am a professional mechanic for over 30 years.

2018 Dodge Ram Pickup

2005 Ram 2500 Quad Cab Short Bed. Xlnt kit, easy install. The installation instructions could have been better. I suggest watching the video on youtube and setting up the rails and hitch on the garage floor first. Take measurements between rail hole rows (row 2 to row 3 - 17 3/4") and add 3/4" for front bed support clearance - 18 1/2". Looking over a rear tire and measuring from the front bed support, My row 2 needed to be rear of center by 1/2". This puts my rear rail at 26 1/4 instead of 26 3/4" from the tailgate. Then everything lined up perfect. The fish wire provided really works great ( threads on to the bolt like a nut). My only problem was the spacer that gets fished with the carriage bolt was to wide for the large hole in my frame. I cut a 1/4" off the spacer and that was the only modification I made to this kit. Not all trucks are the same. XLNT kit, I was impressed !

This is a little confusing. Is the correct measurement 26 34 or 26 1/4 ??I installed a Curt rail kit a couple years ago. I do recall that if you use the instructiondimension...things line up better on a Dodge front rail if everything would have been about a 1/2 inch further rearward. Is there any way this can be clarified? I am starting on another install today. thanks.

Patrick B.


The most current instructions for part # C16420 rail kit state that the measurement from end of bed to rear most edge of the rear rail is 26-3/4 inches on a 6 foot bed. Check out the instructions linked on the product page for more details and a couple of diagrams.

2012 Dodge Ram Pickup

Installed on a 2012 Ram 3500 long box. The rail kit itself is excellent and appears to be very strong. I was able to install with the truck on the ground and the tires on. I did have to remove the inner fender liners to access some of the bolts for torquing. I do not see how the nuts can be brought to proper torque without the use of a 3/4 inch crowsfoot, as it is impossible to get a socket on some of the nuts. The shock mount welded to the frame on one side is an prevents the use of a socket. The single most important step is measuring properly because there is very little margin for error. The video was very helpful. Took me about 6 hrs without jack stands or a lift, but I'm very happy with the finished product and they went on without interfering with my AIR LIFT 57295 LoadLifter 5000 Series Rear Air Spring Kit.

So far excellent!!!

2007 Dodge Ram Pickup

So here I am 1 year later and 7000 + miles later having towed/hauled a 30' Keystone Cougar with the Curt E16K hitch and bed rails.
I installed the item and it was fairly easy with the help of a friend to help tighten bolts and nuts. On the rails I have the E16K Curt Hitch in a 2007 - 2500 Dodge Ram Cummins. I used to remove the Hitch after every trip. That lasted for the first 2-3 times. It is darn heavy to remove and put back in. So now I leave it installed in the truck and remove it when/if I need to haul something in the bed.

Hope this helps your decision and Happy Hauling :o)


Instructions were spot on, also had viddos on youtube to help as well


The accessories weren't correct for my application but upon researching etrailer products was able to find the correct brackets for use under body.


Very pleased and very appreciative with customer service because when receiving order from UPS the box was torn open and majority of hardware was missing. After taking inventory i called customer service explaining how it arrived the representative immediately ordered another hardware kit shipping out same evening, the install took about four hours with one small modification to a mounting bracket. Works great and very pleased so far



So far really good. Thankyou

2006 Dodge Ram Pickup

Took some time to install but overall wasn't horrible. I'd recommend these rails to anyone looking for this mounting style. Didn't have to remove tires or drill any holes besides through the bed of the truck. They are very strong and solid. is a great place to order from. Great customer service and tons of information for all your trailer and towing needs. I'll be ordering more in the near future. Overall a great shopping experience and a quality product!

Arron M.


Another great item that has worked flawless. Would definitely buy it again!


Works fine for me. I didn't install so Im not sure. Pulls a 14,000 fifth wheel just fine.


Works like it should


I bought a Curt 5TH wheel hitch and it took a bit longer to install then I planned for but It has worked great the customer service is fantastic! I have told my friends about Etrailer and two of them have bought their hitches from Etrailer you will not find a better price.

2007 Dodge Ram Pickup

If you are towing with a Dodge with a boxed frame...This kit works perfectly. Every bend...every bolt hole...every piece and par of this kit fit perfectly....No holes to drill...

Duane I.


Still looks new after near constant use

2010 Dodge Ram Pickup

Received my parts to install my 14K Reese 5th wheel hitch in a timely manner and free shipping .. Started the installation on my 2005 Ram 3500 Dually and the parts all fit GREAT... Installation time was exactly what the instructions said ... The following week we hooked up to our 2010 Cougar 34ft RV and left the Wet Coast of the Pacific Northwet and made the 2600 mile adventure to Northern Michigan.... E-TRAILER is AWESOME........

2012 Ram 2500

It installed just as advertised, the video was helpful but the one I found on YouTube shows an actual install which was even more help by showing some of the minor issues during installation. The written directions were well done too. Also a quality product with a very good website to help order the right parts with ease.

Ed S.


After 1 year still working as when I installed it, nothing loosened up and solid the rails are a definite plus.

2007 Chevrolet Silverado 2500

I spent a few hours researching hitches before i settled on the Curt installation kit to go with my Anderson hitch. The directions were easy to follow, but i recommend watching the video as well. I installed this on my 2007 Dodge 2500 on my garage floor. I am sure this added a bit more time to the install, but for my first ever hitch install I had it installed and cleaned up in about 3 hours. I would definitely recommend this installation kit. etrailer was also very responsive to make sure they had my correct mailing info since I use a P.O. box for mail.

Dodge Ram Pickup

Etrailer is a company that I will recommend to anyone that has the need for trailer equipment. Thank you to the team that got my order shipped ahead of schedule. As for the Curt Q20/R20 hitch and installation kit it was a fairly easy installation on my Dodge Ram 2500. Everything was exactly as the videos on the etrailer site had stated.

2004 Dodge Ram Pickup

This kit fit my 2004 Ram 2500 exactly as advertised. Took way longer than the 90 minutes the directions state, to install, but I took my time and made sure all steps were done correctly. Something I should have done, that is not mentioned in the directions, is to "pre-mount" the hitch on these rails, prior to drilling and bolting. If you get it even a bit off parallel, you have I do..when trying to dismount the hitch. I will have to fight it, to put back on these rails also. My fault, not the kit. Etrailer is very helpful, quick and responsive. They have me as a repeat customer already.

2010 Dodge Ram Pickup

The worst hitch I have ever installed! All the pieces are nicely built and appear that they will hold up well, but I would rather install a universal hitch any day.

While I did not have to drill any holes in the frame, it was still a nightmare to put in. The bolt locations are next to impossible to get to with an end wrench much less a torque wrench.

The worst part is the exhaust hits heavy on one of the brackets. No fixing this....

2006 Dodge Ram Pickup

What a Pain in the Butt. Watch the Video. It will help. Be ready to order additional parts/spacers if needed. You can do it by yourself but could really use another person at times. The rear tire removal is very helpful. Drop the rear drivers side shock tower. Then the back is pretty easy. The front is a pain. My brackets didn't reach up to the bed so I had to use spacers on top and bottom. Didn't have enough to do it so I had to order more. The screws for that location were too short so I had to go to Lowes to get longer ones. Those were a pain to get the nut on. I am still working on getting that done. Other than that, it does work.


This is the second time I used this hitch mount. It wasn’t too hard to install on the ground. A vehicle lift, as shown on the product video, makes it look a lot easier but install is still very doable. The video is necessary to have in addition to the enclosed instructions.

The ordering staff has always been friendly and knowledgeable about the product.

etrailer will continue to be my first stop for all my RV products.

2007 Dodge Ram Pickup

This is the 2nd order that I have placed with this company. I've been very pleased with the quality of the product and the Great customer service. I Highly recommend etrailer for any of your trailer/towing needs. My next order will be a shock absorber towing system for our 5th wheel. Great job etrailer, keep up the good work.

2005 Dodge Ram Pickup

Easy to deal with, good communication and quick response.
