2014 or Newer RAM Promaster Curt Class 3 trailer hitch w/ 2″ Receiver


I’ve heard a lot about CURT hitches… Why is that?

CURT is one of the largest if not the largest provider of hitches in the USA and possibly the world. In fact, the manufacturer says that their class 3 hitch is the most commonly installed hitch on SUVs, trucks, and other vehicles like your Transit, Promaster, or Sprinter van.

Can I use this on other vehicles?

The answer is yes with a few caveats. The major caveat is that your vehicle has to be able to use a hitch. It may seem like common sense but it is not always the case. The owners manual of your vehicle will tell you whether or not you can use a hitch. Otherwise, you may cause your vehicle problems. because it was designed with enough structural integrity to handle the rigors of transporting weight. It is especially true if you ask it to transport weight across a very specific point of contact where the hitch will affix to your vehicle. It is a lot of weight for a vehicle to bare if the area was not designed for towing and damage is possible if it was not designed for that task.

What is the gross trailer weight capacity of this particular hitch?

The manufacturer says that this is 5,000 lbs of weight.

What about the tongue capacity of this thing?

What tools am I going to need to install this thing? Do you know? I want to make sure that I have everything I need before attempting to install this 13710 hitch.

Sure. The manufacturer says that you need a ratchet, 15mm socket, 16mm socket, 3/4″ socket, T30 Torx bit socket, and they also strongly recommend that you have safety glasses.

I’m not going to have to drill into my van to install this piece then?

Nope. You will not have to break out a drill to install this hitch.

Any idea how difficult of an install this thing is?

I’ve heard that this has some kind of fishwire hardware, is that true?

Yes. It looks like the fishwire hardware has to do with the mounting hole and the access hole. The picture with this fishwire hardware is either above or to the right of this sentence. It is clickable and it opens a new window if you want to have a better look at what we are talking about right here.

Am I going to remove anything to put this thing in?

We see a picture that seems to denote that you will have to remove a part. It says that it is only temporary, however.

Is there anything I need to do once this thing is installed?

Is it able to accept hitch-mounted accessories?

Yes. You can use most ball mount to standard tow trailers, single horse livestock trailers, utility trailer, and large campers as long as you are not going over the weight capacity of your vehicle and your hitch. You can also use bike racks or cargo carriers.

What is this thing coated with?

It has a liquid Bonderite coating and a powder coat so that it resists scratches and rusting much better than if it was left untreated.

Does this thing have a warranty?
