Video Transcript for Review of Stealth Hitches Ball Mounts - 391BMU7S

Ellen: Hey everyone. I'm Ellen here at etrailer.com. Today, we're going to be taking a look at these Stealth Hitches ball mount. Now, this is an accessory to add onto your existing tow package from Stealth Hitches. Each vehicle has a custom fit kit to make sure you have all the components that you need to tow safely. So this is going to be an accessory too that is not going to replace that tow package.

So be sure that you already have that tow package so that you have all the things, like your safety chain loops, your wiring bracket, and all that good stuff.This one is going to be the tallest one available, so if your vehicle sits a little too low to be level out with your trailer, this is going to be the one you need. You want to make sure that it's a fit with your vehicle. The way to do that is to check the chart on the product page here at etrailer.com. It's got all the vehicles that are listed to be compatible with this ball mount, and it'll also tell you the ride height or the ball height once this is mounted on your vehicle. So check that out, make sure all those measurements match and you should be good to go there.The reason why you want to make sure that your vehicle is level with your trailer, is to eliminate any kind of issues that can happen while you're towing.

If the ball mount is pressing too far down onto your trailer, it can cause some issues. And also if your vehicle is too low and then your trailer inaudible 00:01:19 kind of having to come down and meet that, can just off balance your trailer and cause some issues with sway and all that. So we want to eliminate that as much as we can, make sure that everything's level so we have the best experience possible, while you're out there towing, and also staying safe on the road.This is going to have all the same features as your original ball mount. It's going to mount the same way as that ball mount that comes with your tow package, so nothing changes there just gives you that different height. Again, this is going to be the tallest one, so hopefully that's going to be the right height that you need.

It does not come with a hitch ball, so you will have to pick that up separately. There are several options you can find here at etrailer.com. You just want to match the ball size with your coupler, and then there's also a carrying case that you can get to hold this as well as your receiver tube, so you have a place to put all your stuff, and keep it together. That way you're not having to search for things, you're not clinking around in the back of your vehicle and causing some issues there.Has a nice welded reinforced bracket to make sure that we have a nice, rigid spot for our tow ball to be mounted up to. As far as measurements with this, the total length is going to be 13" from the back to the front, the length from our hitch ball to the center of the ball attachment point or the ball mount attachment point is 10".

The thickness of the base is 3/4", and then that ball hole diameter is 1". So any of those ball mounts will work that have a shank diameter of 1". All those hitch balls I had listed on the screen, they should all be compatible with this guy. Just want to get those different or match the size of your coupler ball with your coupler on your trailer.It does have a limited lifetime warranty and nice black powder coat finish, so it should stay looking nice for a long time, but that's pretty much all there is to it for our look at the ball mount for Stealth Hitches. I hope this video has been helpful in deciding this is going to be the right one for you. If not, we do have a couple other options available here at etrailer.com. There's a couple that are a little bit shorter than this, so if you need to get something that's a little bit less tall than this guy, we should have you covered. But again, I'm Ellen here at etrailer.com. Thanks for watching..

  • Can Stealth Hitches Hidden Trailer Hitch 391AUDQ518 For 2018 Audi SQ5 Be Used To Tow A Boat Trailer?
    We have just what you need! The Stealth Hitches Hidden Trailer hitch receiver # 391AUDQ518 you were looking at for your 2018 Audi SQ5 is not rated for towing and is only rated for carrying accessories like a bike rack or cargo carrier. Using it to tow will void the warranty of the hitch. Since you do not need all of the wiring for towing your 17' boat then you can just purchase the Ball Mount for Stealth Hitches Hidden Receiver Hitch # 391BMU7S which can be used in place of the receiver...
