How to Install a Trailer Hitch on a 2015 Chevrolet Silverado 2500


Today on our 2015 Chevrolet Silverado 2500 we're going to be taking a look at and installing the Curt Trailer Hitch Receiver Class 5, part#C15860. Here's what it's going to look like once it's installed. As you can see it's got a nice powder-coated finish. That's going to protect it against rust and corrosion. It's got a really large safety chain loop. It's a 2 1/2 X 2 1/2 receiver, Class 5. It's going to allow you to have 20,000lbs of trailer weight.

That's the pulling. 2,700lbs of tongue weight, that's your downward force, that's your receiver. Now you want to make sure your truck is actually able to pull that much weight by checking with your manufacturer or your owner's manual. Now this hitch is going to be a large tube that's going to hang down below your bumper, as you can see. It's going to protrude past your bumper on the backside about 4 inches. It does require you to drill two holes in our frame.

The rest of it is going to simply bolt on with the hardware supplied and we're using some of your factory hardware. We'll go ahead and give you some measurements. It's going to help you in picking out your accessories, such as a ball mount, cargo carrier or bike rack. From the ground to the top of the inside of the hitch receivers is about 22 inches. From the center of our hitch pin hole to the end of our bumper is going to be about 3/4 of an inch that it's going to stick out past our bumper. Let's go ahead and show you how to install it. To begin our install we're going to need to remove our spare tire off of the vehicle.

We're going to need to remove this factor heat shield and set it aside for re-installation at a later time. Three 00:01:58 13mm bolts. If your vehicle is equipped with a factory style hitch that's going to go under . That's for a ball mount through your bumper, this large bracket here, we're going to need to remove that. We're going to have a large 21mm bolt on the bottom, on each side.

We'll have two more on the side that we're going to take out and we're going to save all these bolts for re-installation of our new hitch. There will also be two 13mm bolts on the inside that we're going to take out. Then we'll take out these two 13mm bolts. This bracket is not going to be re-installed so we're just going to give that back to our customer. I'll go ahead and flip this out. Now we're going to get an extra set of hands and we're going to set our hitch up into place and put in the two rear bolts. We've put on their N14 00:03:12 bolt with our conical tooth washer, teeth side up. We're going to snug them up, just to hold the hitch in place. We'll snug up both sides, making sure that we have it level at the back here, on both sides of the frame, so we have it centered. Once we have it centered we're going to drill out the forward two holes, one on either side, we're only going to use one hole. We're going to have to drill at this hole and on the other side will be the forward most hole, as well. We're taking a c-clamp to hold it in place. We're going to mark our holes. Once we have it marked we can lower our hitch back down and drill out our holes to accommodate a 1/2 inch bolt. We'll get an extra set of hands because this hitch is very heavy. Starting with a small bit and we're going to work our way up. This is going to take a little while because this is a very large and thick part of the frame rail. It's double-walled. You can just take your time and just keep enlarging the hole until we get to our final size, which should be a little bit larger than a 1/2 inch so our 1/2 inch hardware will fall through the hole. I've taken a strap and just pulled our exhaust over to the side to give us a little access room. We can take our 1/2 inch carriage bolt and our block. Once we have our hole drilled out we'll slide it inside the frame rail. Then we can drill out the one on the driver's side. We're going to set our hitch up into place. We'll install these with our flange 00:05:08 nut and we'll take our N14 bolt, with our conical tooth washer, teeth side up and we'll place it into the original weld nut on the frame. We'll repeat this for both sides. Go ahead and round these up until they're snug. We'll repeat for the other side. We're going to take this side bracket. That's going to attach with one of our original brackets that came from our frame. We'll start that into the hole on the bottom one. We're going to take our 1/2 inch carriage bolt and slide it from the inside. We'll start out our flange nut. We'll repeat that for the bottom. We'll have the same process for the passenger side. We can snug up our side brackets. We'll take a 7/8ths socket and we're going to torque them down to the specifications in our instructions. We'll do the bottom four first. Then we'll torque the two sides. Then we're going to re-install the factory bolt on the top side to help hold our bumper into position. The last inaudible 00:06:46 torque will be 3/4ths here. That will finish it up. We're going to re-install our heat shield. The rear most hole on our hitch is going to line up with that hole where this bolt originally came out of so we can just put our heat shield over the top of that. There's a second bolt back here in the back plate. We'll take our 13mm socket and run those back down. We can set our spare tire back into position and we're ready to tow. That's going to do it for our look at an install of the Curt Trailer Hitch Receiver, Class 5, part#C15860 on our 2015 Chevrolet Silverado 2500.
