Video Transcript for Fifth Wheel Hitch Kit Installation - 2016 Chevrolet Silverado 1500

Today in our 2016 Chevrolet Silverado 1300, we'll be installing the Reese Quick-Install custom-based rails installation kit for 5th wheel trailer hitches, part number RP50064-58. Here's what our rails look liked installed. As you can see, they don't take up very much space of our bed at all. They sit relatively flush with the bed so they won't take away from any of our cargo space, especially if we're putting plywood or flat items in the bed of our truck. These rails are constructed of a durable steel construction and have a nice high-gloss black powder coat finish, so they'll give us many years of rust free and corrosion free service. These rails will allow us to attached 5th wheel heads, or gear inaudible 00:00:43 adapters, or any other in-bed accessory that's designed to work with a rail system. We started our installation by removing our spare tire. Once you have your spare tire out of the way, there's this heat shield on the passenger side over the exhaust. It's held in place with several T25 torque screws.

We'll go ahead and remove those. From this bolt right here, you can't get to it with any socket. We're not going to be reinstalling this heat shield. What we can do is just cut around it as best as possible and just take it off that way. We use a pair of tin snips for that. Okay, with that cut off now, want to work on heat shield one out. We have our front rail position in our bed based upon the appropriate measurements for our bed length.

Make sure you follow the instructions exactly so you can place your front rail in the right spot, depending on your bed length. Now, we'll mark and center-punch the holes that we're going to be using. We'll use the center hole towards the rear of the front rail. We'll use both of our outer holes on both sides. All right, with all of our holes center-punched, we can slide our rail out of the way now. We'll drill them out with an 1/8" drill bit.

Now on our driver's side ones we want to be careful we don't drill down too far because our fuel tank's right below. With our holes drilled, we'll slide our driver's side frame bracket up in position and make sure our holes line up. We'll do the same process on the passenger side. You can see how the holes line up on our passengers side bracket, driver's the same way. Now, we can enlarge all our holes to the final size diameter of 9/16ths. I'll be using a step bit for this.

You can use a drill bit. Whatever you have available. All right, now that our hole's drilled, it's a good idea to take some spray paint and paint the inside edges of the holes so you don't have to worry about any rust from forming. We have a spray-in bed liner, we'll just use some flat black. Make sure you get it nice and good. We'll let that dry. We'll do the same for the other ones. Now, our rail will cover this up so we won't see the discoloration. Once it dries, since it's flat black, it will blend in nicely. Now we'll take our 3.4" diameter pull wire, insert it into the hole just behind our jounce stop, right here. We'll route it towards the rear of the vehicle. Make sure we go over this tube here and we'll pull it out a hole inside the frame. Here it comes over the tube and the frame. We'll slide a large, flat washer on, drop it over the tube and we'll thread on our bolt to the pull wire. We'll push that on it. We'll grab our pull wire now. Make sure our bolt is in the right location. Take our frame plate, put our pull wire through this upper hole towards the back. Make sure our pull wire stays in that hole and doesn't get pinched and we'll pull the bolt on through. Let it rest on there for right now. Take off our pull wire. Slide on another one of those large, flat washers, a lock washer and we'll thread on a nut. With that loosely installed, we'll install our front hardware now. Now, our front hardware will go through this upper hole here, next to this raised section, and the hole directly below it. We'll have one of these plates here oriented like this, between our frame and our bracket here. We'll have a second one on the inside of the frame. We'll secure with the 5 1/2" long carriage bolts. One on the inside of the frame and one between our frame and our bracket. We have our bolt inserted on the bracket. We'll slide our other bracket up between the bracket and the frame. Push up on the main bracket and slide it over in the right position and push the bolt through. Okay. Good. Just like that. With the bolt pushed through our frame bracket, just slide on a flat washer, a lock washer and we'll throw on a nut, loosely. Now we'll do the same for the bottom bolt. Go to the upper hole, push it through all the brackets and we'll slide on our hardware from the outside. Now with both of our frame brackets loosely installed, we've slide our rail back into position. We take one of our U-shaped blocks here. We'll slide it between our rail and our bed. Do the same on both holes here, actually. On the driver's side, we'll be using the button heads here. That would be allen holing them with a washer. We'll drop those down, do our rail and do our bracket down below. For our center hole, we'll just use a standard carriage bolt. Drop down. For our passenger's side, we'll use two more of the blocks and two more of the carriage bolts. Now, we'll go underneath and install some nuts. For our middle bolt here, we use a 1/2" conical tooth washer with the teeth facing up towards the bed of the truck and we'll throw it on a nut. We'll loosely snug that down. Now we'll take one of our offset spacer blocks here for round hole. We'll install it onto our bolt here. We'll get a 1.2" lock washer on it. I'll just snug that down by hand. We'll do the same for this one here. Okay, with this nut started, we'll do the same on the other side. With our front rail loosely tightened down on both sides, we'll take our unassembled 5th wheel head and place it onto our rails, so we can get the proper spacing for the rear rail. Okay. With that in, we'll make sure it's nice and square. Now, we'll use our center punch and mark the center spot for our holes. We'll be using the front one in the middle. Now, for our rear rail, we'll be using the second from the out . the ones next to the outer on both sides. We'll just center punch these and we'll drill them out. We'll also be using the Ford center bolt hole. We'll do the same with that. With our pilot holes started, we'll remove our rail and drill them out to the final size for all 5 bolt holes. Then, we'll put our spray paint on, like we did on the front. Do the same for all the 5 holes that we drilled. Take our rail and we'll place it over the holes and we'll drop down our two outer bolts. Now, these are the ones that are next to the outermost, on the rear one. We'll place our unassembled 5th wheel head back on our rails to help set everything up and to help hold it down. Now we'll go underneath and install our appropriate hardware. We'll slide our spacers, the U-spacers in, around our bolts to our frame panel there. Do the same on the other side. We'll put our offset spacer on here. A lock washer and we'll thread on our nut. Do the same for the other side. Now, we'll snug down all of our 3.4" hardware that attaches our rails to our frame brackets. We're using a crow's foot on our 3/8ths torque wrench, in order to tighten these. We'll just torque them to spec. With all four of those done, we'll do the same on the other side. Now, we'll torque our frame brackets to our frames, following the instructions. Now, we'll tighten down the big 3.4" nut. We'll torque the big bolt now. With all our frame hardware tight on this side, we'll do the same on the driver's side. Now, we'll torque our two final bolts underneath. With all of our hardware torqued, that completes our installation. The only thing left to do now is to reinstall our spare tire. That completes our installation of the Reese Quick-Install custom-based rails and installation kit for 5th wheel trailer hitches, part number RP50064-58 on our 2016 Chevrolet Silverado 1500.

Reese Quick-Install Custom Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches - RP50064-58

Average Customer Rating:  4.6 out of 5 stars   (108 Customer Reviews)

Custom brackets reduce the amount of drilling and time required to install your fifth-wheel trailer hitch. Brackets, base rails and hardware included.


Poorly packaged at the warehouse which caused a box failure enroute to my house. I REALLY needed this for the weekend and will now have to either borrow a truck with a hitch or find a kit locally. Customer service blamed UPS. I disagree. Had the box been secured properly from etrailer to begin with, I wouldn’t be writing this review. I will not order anything heavy from them again.

2006 Dodge 2500HD

I was a little leery of installing a fifth wheel hitch to begin with, but after watching the videos from etrailer a few times and reading the instructions a couple of times, I decided I could do it. I installed the RP50064-58 kit for fifth wheel hitches and the Reese 30083 Fifth Wheel 20K w/Round Slider Unit on my 2006 GMC 2500HD short-bed. I had my three grandsons, ages 2, 3, and 7, helping me. The installation went really smooth (other than the younger children occasionally running off with tools) and I am very impressed by how sturdy it is. Now I am looking forward to receiving the Stromberg Carlson 100 Series 5th Wheel Tailgate with Open Design that I ordered. Thank you etrailer! You make it fun and easy!

Ha ha ha Michael I can relate to that have a 3 and a 7 years old and every time I work on something they are there to help the 3 year old more like wants to do it himself . Planing on installing a 5th myself and was thinking they could be of help steping on the bolts top side so I can put the nuts to the bolts, looks kinda hard. Good luck with your venture .

2006 GMC Sierra

I was a bit nervous at first installing the rails that would eventually hold the weight of a 16,000lb camper, however after reading the instructions and looking at the quality of the parts, I felt alot more comfortable. The installation was very easy, and with the large side plates, I feel alot better knowing the rails and hitch are secured to the frame with more than those small pieces of L steel that normally come with the kit. Install only took me about an hour and the hitch is very solid!

2006 Chevrolet Silverado

I have a 2006 2500HD with an existing gooseneck hitch that is welded in place between the frame. I had thought the "custom-fit 5th wheel" brackets would still fit so I ordered them so as to not have to drill in the truck frame. Unfortunately, the gooseneck channel is in the way of where the "U" bolt needed to go on the back side of the frame so I have to return this and get the "universal" install kit / rails. It will still be fine but I was trying to not drill in the frame any more than necessary.

I just wanted to pass this along incase anyone else had the same setup. It will save you some time, frustration, and shipping money :-). It was my fault (not etrailer's) .

I attached a picture showing where the bracket is with the gooseneck channel behind it (in the way). Hope it helps someone else.

2014 Chevrolet Silverado

Not as easy as the online videos would lead you to believe. However I did manage to get it installed. Getting the spacers nuts and lock washers on the bolts over the gas tank on my 2014 Silverado were a real SOB. Dropped 3 lock washer into the shroud over the gas tank while trying to accomplish this. Ended up taping the nut and lock washer to my wrench to get them in position while someone turned the bolt from inside the truck bed.

2004 GMC Sierra

I did not have to take off the spare tire or do anything with my heat shield. It bolted right on took about 4 hours.

Ram 3500

Very good products that are built to last. Nice thick powder coat. My order was an odd one . I ordered a fifth wheel base kit for a Chevrolet 1500. I don’t think many 1500s put fithwheel kits on them, but it’s for a 1500 towable Camper , very short and light. The system kept trying to send me the kit for a newer 2500 or 3500 I guess but we finally got it right with the required pieces to get it mounted. Nice and respectful service on the phone.

2002 Chevrolet Silverado

Very fast shipping for the 5th wheel sliding hitch, rails and wiring ! Installation was very straight forward although the instructions were a bit vague. Watched the installation videos a couple of times which was a big help. Took about 4 hours for everything including wiring. Could have been quicker if I took off the rear wheels and lowered the exhaust but just worked around them. Picked up my new 5th wheel a week later and was very happy with the hitch - No problems at all. This was installed on a 2002 Chevrolet Silverado 2500HD.

Still very happy after thousands of miles !

Had everything needed for installation

2012 GMC Sierra

Per instructions, removal of the vehicle heat shield was a beastly process. Modification of inner fenders was never mentioned in the instructions, had to modify the brackets to eliminate interference fit with hanger on the drivers side on the frame. Had to customize an existing bracket to allow access to mounting bolt on driver side. Also had to modify the frame to gain access to hold 3/4" bolt head for tightening mounting plates. It would have been much better to have had 2 throw away short open end stamped wrenches supplied with the kit in exchange for many extra bolts and other hardware. Once custom fabrication was complete it does work fine.


It wasn't so easy for me as I am 80 yrs. old but I got her done in a days time and it works fine, all the measurements in the directions were right on.


Great kit, everything needed short of tools was included, installed in a couple hours.

Everything is great, no problems!!

2005 Chevrolet Silverado

Instructions leave something to be desired.. and every bolt needed for every variation of truck this kit can go on is included, so lots of leftover hardware. Surprising for a 'custom' kit (not universal).

Other than that, got it installed on my 2005 Silverado 3500 in roughly the time advertised. Almost. Still trying to figure out how to tighten the last nut that is really hard to reach.

No issues after a year. Kudos to etrailer for asking since so many people jump the gun quickly with glowing reviews only to realize disappointment soon after. Not so with this kit all is still good.
Mikey - 08/06/2018


Ordered the Reese Quick-install rail and installation kit for my 08 GMC because the 05 brackets I had did not fit the 08. A friend and I installed it in about 2 hours, had difficulty installing one bolt above the fuel tank but this was to be expected. The instructions were clear and easy to follow. The parts fit perfectly and looked like a professional installation when finished.


Parts arrived in a very short time and all fasteners and directions were in the boxes as expected! Installing was not quick and easy as I thought it would be. Fat fingers I could have done without. My son helped with most of the installation because 4 hands are required! The quality of the product is great as I expected too!

The product is working as I expected. The sun and weather has taken its toll on the paint, but that to I would expect. Great kit overall.

2004 GMC Sierra

The frame brackets and measurements worked out incredibly accurately! I am very happy with my purchase and the install time. I will say this, if installed on a 2004 GMC Sierra 2500, the drivers side frame rail is dished inwardly. Making the 1/2x2” bolt impossible to get in the hole from the inside of the frame out! This problem held me up for at least 1-2 hrs, since I had to grind off and make the actual bolt 1 1/2 long to be able to fit it in the proper location in the frame. It would be nice to accommodate for this in the future.

2006 GMC Duramax

This kit was a perfect fit on my 2006 Duramax crew cab. Installation was a breezy and it did not require any drilling or welding of the frame. The instructions were good and all necessary bolts and nuts were supplied ( along with a lifetime supply of spares). I would highly suggest this seller and their kit if you need fifth wheel rails installed in your truck.

Got my order in record time!
the rails cheaper elsewhere but they couldn't deliver. You could.

2015 Chevrolet Silverado 1500

Easiest fifth wheel assembly I’ve ever installed. Only took roughly an hour and a half to do a complete installation. Very detailed instructions included with the kit. Definitely the way to go over a universal style bracket assembly.

great product but the Instructions ARE THE WORST I EVER SEEN

Thank you for your review. understands that written instructions are sometimes difficult to read. That is why we make our own video installs. See this kit install below:

2014 Chevrolet Silverado

I bought a new Chevy 2014 Silverado Double Cab 4X4 with the 6' 6" bed and needed a bed rail kit to mount a fifth wheel hitch from another vehicle. Plan on spending 6 - 8 hours to install it if you have no previous experience with this installation. Make sure you have less than 1/4 of a tank of gas as the installation requires lowering the gas tank down about 12 inches. You will also need to remove the spare tire. You will save yourself a lot grief by doing these two things first. Also note the position of the bolts that hold the rails to the brackets, the front rail uses the outer most holes. The rear rail uses the second set of holes inward from the end of the rail. If you have a bed liner, trim it first before doing anything else.

This is a well designed heavy duty product. I have purchased several different products over the years and never had a complaint. Their service and pricing have been great.


I was happy with this set of rails. I chose to have them installed, but my installer said they fit well and were an easy install. I have used them now with multiple 5th wheel and gooseneck hitches.

2002 Chevrolet Silverado

I brought this 5th Wheel rail kit to a local Hitch Installation and Welding shop, and they installed it for me in one day. I brought the Hensley Trailersaver TS3 5th Wheel Hitch as well, so that the whole assembly could be line-up precisely as prescribed, with the center of the Kingpin at 1-5/8" forward of the truck drive axle center line. Great product by Reese, that fit my 2002 Silverado 3500 perfectly. Would recommend Reese products to anyone contemplating towing an RV/Travel Trailer.

2005 Chevrolet Silverado

Like a few of the other reviewers, I decided that the custom brackets for my 2005 Silverado 2500HD with 6 1/2 foot box was the way to go because I didn't want to be drilling and fitting the smaller brackets under there. Here's some thoughts. Yes, the spare tire really needs to come down - that took me about 2 hours, as I have never had it down before and had to keep referring to the instruction manual. Making measurements for the rail placement and drilling the holes in the bed was the easy part, as was using tip snips to remove a section of the heat shield underneath. The hard part was drilling the optional hole in the frame for the 1/2 inch bolt and fishing the bolt through on the drivers side (passenger side was an easy fish). I started with 1/2 inch hole for the 1/2 inch bolt - ended up drilling a 9/16 hole so the bolt would come through. Still, I do feel comfortable that this bolt provides extra security/rigidity to the brackets. The other hard thing to do was get the rectangular offset hole plate and lock washer attached to the rail bolts up by the fuel tank. Ended up hot gluing the lock washer to the plate because I was out of fingers to hold the pieces up there and thread the nut onto the bolt - ideally one would need to be part stretch armstrong and part contortionist. My total installation time was closer to 5-6 hours - but when it comes to something like this, I would rather be slow and thorough than fast and miss something. The kit contained everything needed and even a few leftover parts - so don't be concerned. Towed my new trailer home 2 nights ago and was pleased with the set-up and how it towed.
