Video Transcript for Fifth Wheel Hitch Installation - 2008 GMC Sierra 2500 HD

Today on this 2008 GMC Sierra 2500 HD we will be installing Curt fifth wheel Q5 with roller part number 50064 and part number 16500. We will also be installing the fifth wheel installation kit with rails part number 50061-6008. Go ahead and lower the spare tire up out of the way. Also on some models you will find that the heat shield over here on the passenger side will interfere with the installation of your frame brackets. If that is the case you may want to go ahead and remove the heat shield out of the way as well. Okay on the models that have the factory installed electrical brake control unit will need to relocate the electrical plug mounted to the inboard side of the driver side frame rail here. Loosen those up and you can see that we can actually take the heads of the bolts, slide the bracket forward, and pop them out those larger holes there. 00:59

What we are actually going to do is to install the new bracket that is provided with our installation kit. Then this larger hole here will help us hold it on later on when we install the actual brackets to the side of the vehicle. Okay the next step is to go into the bed and we are going to go ahead and set up our front rail, the one closest to the cab. We want to check the dimensions that are listed in the in the instructions to verify the distance from the tailgate that we are going to be setting our rail onto. This is actually a short bed model, this is a 6 1/ 2 foot bed. For this model we are going to be coming from the end of the bed here to the front edge of the bracket. We want to set it up at 47 1/ 2 inches. We also just want to center the rail in between the wheel wells as well. 01:48

Go ahead and mark our holes here. On the front rail here we will be marking out the two outside most holes on each end. I am going to just simply take a Sharpe, mark those. Go ahead and move the rail out of the way and drill those holes out with 1/ 8 inch drill bit. We want to be especially careful when drilling out the driver side holes, especially the front one because the gas tank is located directly below the bed here at this attaching point. To check the alignment you want to line up this hole and this hole with the existing holes here in the frame. So you want to double check the ones on the passenger side as well. Then we can go up in the bed and enlarge those holes to 9/ 16. Next we will go back underneath the vehicle. We are going to loosely install our frame brackets to the side of the vehicle. Here from the inside of the vehicle you can see the oblong hole here at the rear attaching point for our frame bracket. You can see the hole in the frame bracket that it is aligning there. We will be attaching that with the 3/ 4 inch hex bolt here into the bracket. We are just going to rotate that. Slide it into the oblong hole in the frame and we will be attaching on the back side with the flat washer, lock washer, and nut for the U bolt that is provided with our installation kit. We have got two holes here that we can use that we will be using in the coinciding hole here at the bottom as well. Here you can see the two holes at the bottom of the frame bracket where our U bolt can align. Again you just want to take the one that is probably going to be the best clearance for you and the tightest fit. 03:36

You do want to make sure before installing the U bolt that you check to see if there are any lines that are going to be in the way when you do install it. You want to make sure that those are pulled out of the way so they do not get pinched. On this particular model that the forward set of holes are the ones that are going to provide the easiest set of force with our U bolt. We will be attaching on the back side with the flat washer, lock washer, and nut. We are just going to kind of hand tighten these for the time being until we make our final adjustments. Okay now we have got the frame brackets loosely installed on the vehicle. We can go ahead and go back in the bed and we are going to go ahead and mount our front rail. Align it back over the holes that we drilled earlier. We will be installing through those holes the 3/ 4 by two inch carriage bolts. Okay since where we drilled our holes is actually at the bottom portion of the ribs in the bed we are going to want to go ahead and put the spacers in between the rails and the bed so that we can ensure our metal to metal contact. We need to do that at all four locations. With those in what we want to do is go ahead and take the feet of our fifth wheel head and bring it up in here. What we are going to do is go ahead and test fit it inside of this rail and that will help us line up the rear rail as well. Okay with the rear rail centered we can go ahead and mark our holes. On the rear rail we are actually going to be drilling the second set of holes in from the end on both sides. You will notice that this set of holes is going to be sitting on the upper corrugation of the bed so that the spacers that are going to be put in the front rail are actually going to be under the bed on the second set of holes. I am just going to go ahead and remove the roller assembly. Move my rail again and go ahead and drill my holes out to 1/ 8 inch like we did previously. Check our alignments underneath with the frame brackets and then enlarge them to 9/ 16. Next we are going to take our 1/ 2 inch by two inch carriage bolts. Drop them through the holes that we just drilled. You need to do that at all four locations. Okay what I am actually going to do is set the slider assembly back into the rails here and then we will go underneath and tank those down. Okay and then back underneath the vehicle we are looking at the bolts that are coming through the rear mounting rail. The spacers that we used above the bed on the front rail we are actually using under the bed here. You need to do that at all four locations. We are going to attach that at the bottom using a block, lock washer, and nut. You want to repeat that set up for all of the bed rail mounting boards. Once we have got all of the fasteners in position we want to go ahead and torque our bolts down. 06:27

We are going to start with our 1/ 2 inch carriage bolts holding the bed rails to the frame brackets and then we will move on and torque the bolts holding the frame brackets to the frame of the vehicle. You will likely find that on most if not all carriage bolts that you are not going to be able to get a torque bar in there to torque them down. If that is the case just go ahead and take an open ended wrench. Get it as tight as you can with your hand and then get a breaker bar in there and give it about 1/ 4 turn and that should get you right about at your torque rating. Your torque ratings are listed in the directions. Okay with all of the bolts torqued down the installation of the fifth wheel components under the bed are completed. Coming back up inside the bed here we want to go ahead and put the hat on to our slider assembly. You can see we have got both holes here on the side of the head assembly we are going to be attaching to the slider assembly using the provided hex bolts, lock washer, and regular washer. Those are going to be going from the inside out like so and they will be threading into the existing weld nuts here on the slider assembly. Then we need to tighten down the bolts on the head assembly. We want to the pin in through the hole in the base rail and then add the clip on the back side. Then we want to torque the bolts on the head assembly. You want to check with the directions to verify the appropriate torque rating. And then when you need to use the slider assembly you simply turn the release handle and pull the vehicle forward and it will slide back into place. With the head assembly installed we just want to make sure that if you had removed your heat shield earlier that you put that back up into place and we also want to make sure we put our spare tire back up and our installation will complete. This will conclude the installation of Curt fifth wheel 50064.

Reese Quick-Install Custom Bracket Kit for 5th Wheel Trailer Hitches - RP50064

Average Customer Rating:  4.8 out of 5 stars   (526 Customer Reviews)

Custom brackets reduce the amount of drilling and time required to install your fifth-wheel trailer hitch. Hardware included. Base rails sold separately.


Fits great and works well on my 2005 Sierra 1500 ( 5 1/2 )short bed.


Can’t use the carriage bolts that you supplied, except in the middle of the rail. There’s no room to put a socket on the nut between the beam and bed, there’s just enough room to use an open end wrench and torque the bolts from the bed side, Which means you have to buy 8 bolts. A video stated the same thing, you believe it’s a one man’s job, it’s not. That’s why you supplied the carriage bolts.


Missing parts, not quick install


Good quality


Delivery time was excellent ( about 3 days)! Driver's side bracket was extremely difficult to put washer,lock washer, and nut on carriage bolt coming from hitch rail in bed because of limited space between bed underneath and fuel tank. Would have been easier to remove fuel tank, but didn't want to do that. Very hard to get hand in tight places to manuever nut and especially tighten. Over all I am well pleased with product and exceptional customer service!

Very much agree...

2005 Silverado 2500HD Ex Cab Short bed. I was very impressed with the turnaround time for this kit. I was in a real panic as I had a deposit down on a 5th wheel and needed to pick it up the weekend after. Package came in good time and I was able to get my trailer on time. Installation was a breeze once I figured out that the Reese instructions are really a VERY rough guide, and can be misleading and contradictive in placed. You have to double, and treble check what you are doing. were great to deal with and I wouldn't hesitate to recommend, and use again. Web site is easy to navigate and there are lots of questions asked, and answered. This is how to do business. Thank you. Jeff. W


I installed this "custom" mount which was not very custom on a 2011 Silverado 1500. I understand that this mount fit '07-11 model years and may have fit better on the earlier models, but it layed so poorly on the frame of my truck that I was sure I had the wrong mount. etrailer gave me the number of the manufacturer customer service and they assured me I had the correct parts and to bolt it up and it would bend to fit. Long story short, I've done a few of these in the past with very little problem, usually a 2hr job. I had 8 long hours on this one, but finally made it work. This site has a nice video of the installation on a 2008 model. I would love to see the video of the installation on a 2011. They better have a lot of film!!


Vince from customer service was very helpful in getting me the parts I needed. Item came in 2 days, was well built and made Installation straight forward and easy without having to drill holes in my truck frame. This being the first 5th wheel hitch I have ever installed, I was glad I ordered these. I will definitely use the custom brackets again in any truck I have and will also use for my towing parts.


It is a install kit for my 2007 GMC for a fifth-wheel hitch rail set. The adaptor works great. Using the inclosed directions the rails lined up right on for the hitch.


Ordered a fifth wheel kit for my sister's Ford Super Duty. Order was received really soon. Easy to install, fitment was great. I then ordered a frame bracket kit for sisters Silverado. Even though the brackets were on national back order, I was updated on progress regularly. Received kit this week. Thanks Will recommend you to my friends.


This product was exactly as described the holes matched perfectly to the frame of the truck and made installation of the rails a breeze. It will take 2 people to do this installation so don't try and tackle by yourself. ordering rep was extremely knowledgeable. and ordering was simple and efficient. ground shipping arrived 2 days early.


Received my order in 2 days(I was extremely happy with that). Started to install brackets only to find one bracket was defective. I contacted customer service and explained the problem. 2 days later I received the replacement.VERY pleased with e trailer.


Product works as described, was a bit hard installing, but install went well with the detailed instructions and the help from Etrailer, thank you all again for the help and install kits from Etrailer.




i am very happy with the custom fit brkts. . installation was a no brainer . it took two of us about 2 hours to install complete hitch . not to mention the customer service was great !


After we finally got all the parts[the first order was broken open in shipping and parts were missing] we installed theRP50064 with ease and would recommend this product and similar types of frame brackets.


Fit was right on. The paint on the other hand. Had to repaint do to shipping wear. Be sure you have extra bolts. needed 4 extra 2" bolts for a 05 silverado. The brackets stick out 3/4 in in the middle. could not use air bags with this setup. :(


the service department was a pleasure to deal with . order came in within 2 days very quick. for me the brackets installed pretty easily even though there were in instructions to install the brackets , i have done this before so was not to big a deal. all in all the staff are wonderful to deal with , thank you.


Great product. Sure made the install so much easier. The instructions are a little lacking when it comes to the rail bolts above the gas tank. Use the hex bolts and a helper there.


Was pretty easy to install. My truck had very little room to work with so i had to buy regular nuts and bolts and needed 2 people to install otherwise good product


Still not sure this is the right item, but the support was great and I'm in the process of verifying details for my unique situation.


The parts were very good quality and mounted to my truck with no modifications. Service and delivery were excellent. I have used them on multiple occasions.


I haven't installed it yet but it seems to be of good quality.

The product is working out great.

Easy installation


I hope this is for a 2005 3500 long box not a 2009 I haven't installed it yet waiting to find out
