It was the exact replacement hitch for my Stealth hitch that was lost….thank you Jeremy for assuring that I got the correct part! And it was here in mere days too!

Very solid ball mount with no play or slop in the connection. Tows smoothly and disappears when not in use.

This hitch was a must have so that I could own a Porsche Turbo GT and still have a tow vehicle when needed on rare occasions. I made a replaceable cover between the exhaust pipes and hid the plug behind a hinged license plate. I then used stainless steel shackles to help facilitate connection of the safety chains. Had to remove bumper for install, but it was well worth it. Just keep the OEM bumper as it will be needed if you sell the vehicle to make it a certified pre-owned (CPO).

As I have indicated in a prior review, the whole thing is a big gimmick. Yes, the hitch is hidden, but that is really the only benefit. It's hard to use, comes with a mediocre wiring harness kit for the car, and overall you can get spare parts, but they cost time and money. The whole reason I needed to buy a second stealth hitch receiver is because I lost the first and it is totally proprietary. Overall, I WOULD NOT RECOMMEND. Stick to the standard square mount receiver.

1 year update. Let me reassure you, I have not changed my mind about this product. Do Not Buy. I have already bought the factory wiring and hitch. Go with the right thing to begin with, you will not be disappointed.

- Solution For Adding More Rise To Stealth Hitch Ball MountHello Brian, thanks for reaching out. We do have a product that will help with this. Take a look at the following: - Ball Mount for Stealth Hitches Hidden Receiver Hitch # 391BMU7S This provides more rise than the standard ball mount that came with your hitch. This will raise the ball height to 20-1/2" when installed on a 2022 Volvo XC60. This will allow your trailer to be much closer to level. Typically, anything within 3" of level is considered safe to tow.
view full answer... - Will the Curt RockerBall Shock Absorbing Hitch Ball Work w/ a Stealth Hitches' Ball Mount? No, it can not Jeremy. The Curt RockerBall Shock Absorbing 2-5/16" Hitch Ball item # C82KR is not compatible with a Stealth Hitch ball mount like item # 391BMU7S. Those ball mounts only work with a standard hitch ball like the BulletProof Hitches item # BPH63RR. We're pretty limited with Stealth Hitches so I do not have any way to help you with that height difference.
view full answer... - Ball Mount For 2005 Chevy SSRWelcome back, Bill! The hitch GM used on your 05 SSR was actually made by Oris, which has a different attachment mechanism than the Stealth Hitches. Unfortunately, there is no way to make them work together. I did actually find the Oris part that would have originally come with the hitch (their part number ORS01122254020), but to further compound the disappointment, it was discontinued quite some time ago (I couldn't find an exact date, but it looks like somewhere between 7 and 10 years...
view full answer... - Is There Stealth Hitch Ball Mount Attachment with More RiseHey Jim, so we have three options for different height ball mount platforms for the Stealth hitches. The part # 391BMU7S which is probably too tall, the part # 391BMU5S which is probably the one Stealth wanted you to get, and the part # 391BMU5L which is similar but longer in length. I would reach back out to who you talked to and ask for a part number of what they recommended. It looks like today you ordered the part # 391BMU7S which might be on the taller side but it probably will...
view full answer... - Can You Change The Ball Mount Height On The Stealth Trailer Hitch Receiver For a 2017 BMW 3 Series?The Stealth Hitches Hidden Trailer Hitch Receiver w/ Towing Kit # SH33VR will come with a 7" Ball Mount # 391BMU7S. When we had this installed on a 2014 BMW 3 series it had a ball height of 18-1/2". You can get either the 5" Ball Mount # 391BMU5S to drop the hitch 2" or the 3" Ball Mount # 391BMU3S to drop the ball height 4". I recommend installing the hitch and connecting your trailer with the 7" ball mount to determine how much your suspension will sag to determine which ball mount will...
view full answer... - I Need Help Identifying A Specific Ball Mount. Can You Help?That is a ball mount for a stealth hitch brand trailer hitch, with what is likely a 1-7/8" or 2" trailer ball. You can replace the ball mount with part # 391BMU7S. For a 1-7/8" trailer ball you can use part # A-80, or part # A-82 for a 2" ball.

- Recommended Trailer Hitch for a 2018 BMW X5No, the Ball Mount for Stealth Hitches Hidden Receiver Hitch # 391BMU7S is not going to fit your 2018 BMW X5. The only ball mount that fits your Stealth Hitches Hidden Trailer Hitch Receiver w/ Towing Kit # SH52VR would be the one included in the Towing Kit w/ Ball Mount and Trailer Wiring for Stealth Hitches Hidden Rack Receiver # SH98VR. Realistically, the only thing you can do is swap your hitch out with a regular hitch like the Curt Trailer Hitch Receiver # 13077 and use a ball mount...
view full answer... - Video that Shows How Stealth Hitch Hidden Ball Mount and Hitch Opening AttachIf you check out the install video I attached to this page for a similar Stealth hitch you'll see in the beginning how the Stealth hitch inserts like # 391RR2 and # 391BMU7S install into the main hitch tube of the hitch. Nothing else would be needed to order.
view full answer... - 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...
view full answer... - Stealth Hitches Trailer Hitch & Access Hole Cover That Fits 2019 Tesla Model 3Definitely a smart idea to check, and the Stealth Hitches trailer hitch does fit your 2019 Tesla Model 3, as does the ball mount, so here is exactly what you will need for your 2019 Tesla Model 3: - Stealth Hitches Hidden Rack Receiver # 391TES317 - Ball Mount for Stealth Hitches Hidden Receiver Hitch # 391BMU7S Then for a hitch ball, depending on your trailer's coupler size you will need either the 1-7/8" Hitch Ball # C40002, 2" Hitch Ball # 40038 or 2-5/16" Hitch Ball # C40007.
view full answer... - Recommended Ball Mount Attachment for a Stealth Hitch Hidden Rack Receiver Hitch Hey Jorge, you are correct you are going to need the Ball Mount for Stealth Hitches Hidden Receiver Hitch # 391BMU7S to be able to tow with your Stealth Hitches Hidden Rack Receiver # 391AUDQ518. You'd also need a ball mount like # 40038 for a 2" ball, or # C40007 for a 2 5/16" ball depending on what your trailer needs.
view full answer... - Ball Mount And Sway Control For 2022 Audi Q7 With Stealth Hitch Hi Isabelle, welcome back! The Ball Mount for Stealth Hitches # 391BMU7S will work with your existing hitch. On a 2022 Audi Q7 this will give you a hitch height of 20-1/2" so make sure that lines up well with the Airstream. This does not include a hitch ball, so you will need # 40038 for a 2" or # C40005 for a 2-5/16" ball. The Curt True Course Advanced Bluetooth Trailer Sway Control # C94VV installs on the trailer side, so it works with any vehicle that has a 7-way. Do you have a 7-way...

Make sure that if you plan on towing, you get the safety chain anchors as well. Product is sturdy and I tow a Scamp camper and small utility trailer.
