Note: The included receiver attachment is only for hitch-mounted accessories and cannot be used for towing. To tow with this hitch, you must use the included ball mount attachment.

This Stealth Hitches trailer hitch includes everything you need to hook up your trailer for towing. The ball mount pops into the hitch's center block so you can attach your trailer's coupler to the hitch ball. The wiring harness lets you power your trailer's lights. And the safety chain loops let you attach your trailer's safety chains. A receiver attachment is included as well for those times you need to use a bike rack or cargo carrier instead of towing your trailer. This all-in-1 solution saves you the headache of scrambling for missing parts, so you can get on the road faster than ever.

Completely Hidden Design

Nothing can ruin the clean, stylish look of your vehicle like a giant piece of metal bolted beneath the bumper. Luckily, with the Stealth Hitches trailer hitch receiver, you never have to worry about messing up your vehicle's lines.

hitch in use comparison

This hitch installs behind your bumper, keeping the cross tube concealed and leaving only the ball mount visible. Even better, the ball mount can be easily removed from the cross tube when it's not in use, so you won't see any trace of the hitch. This means that you can retain that clean, from-the-factory look for your ride, while still being able to tow your trailer on the next family road trip.

This hitch also comes with a removable 2" square receiver, which can be used to mount any variety of hitch accessories, like your bike rack or cargo carrier.

Simple Set Up

Both the ball mount attachment and receiver attachment can be installed and removed in seconds with no tools required. Simply pop the selected attachment's base up into the stainless steel block at the center of the hitch until it automatically latches in place.

center block locking

Be sure to then press the lock on the side of the block to fully secure the attachment. When you're finished hauling, use the included key to unlock the latch. Then turn the handle on the block clockwise and remove the attachment. You can stow the attachments in a safe place like your vehicle's rear cargo area, or you can use a convenient carrying case (391CASEC - sold separately).

hitch plug and center block

And when you're not using an attachment, the included hitch plug covers the center block's opening to protect the hitch's body from dirt and debris.

Wiring Installation


The included wiring splices into your vehicle's wiring harness, which is located in your rear cargo area, on the driver's side. Once you've made all of the necessary connections, insert the provided fuse into the in-line fuse holder.

Once installation is complete, the 7-way connector will mount beneath your hitch. A mounting bracket is included to attach the connector to your hitch.

7 way connector on hitch

It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 7-way connector itself - to help prevent corrosion. Technical Support

Stealth Hitches Hidden Trailer Hitch Receiver w/ Towing Kit - Custom Fit - 2" - 391AUDQ818T

Average Customer Rating:  3.5 out of 5 stars   (2 Customer Reviews)

Tow your small trailer with this completely hidden trailer hitch. Remove the ball mount for a fully concealed look when you're not towing. Use the included receiver attachment to mount a bike rack or cargo carrier. Trailer wiring included.


Summary: More gimmick than practical. Would recommend OEM/dealer hitch/wiring. (I later bought the OEM wiring harness.)

Our Audi Q8 did not have a hitch. The same day I bought the car, I placed the order for the Stealth Hitch.

Installing: Installation for the hitch receiver has instructions that are straight forward in my opinion, and I installed the receiver in just hours. The car bumper will need to be cut. HOWEVER, the aftermarket wiring parts and instructions were Awful. It requires wire taps to gain access to the signal from the car, which cuts into the insulation (I don't personally like). It's not the worst thing.
The worse was running the power wire from the back of the car to a battery terminal at the front of the car. While there may be alternatives, if you are following the instructions (there really aren't any for this part), you will struggle and have to make things up on your own, passing a 12 G +'ve wire past things with sharp edges.

Using: As the name implies, it's nearly invisible. I really like that the towing ball has no rattle when hauling. These 2 reasons are why it gets 2 stars from me. EVERYTHING else is a fail! #1 if you loose the receiver ball adapter, you will need to buy another, which is $xxx (and shipping time lost). It's design is totally proprietary. You cannot "borrow" a friend’s receiver or go to [moving company] or [hardware store] and get a new one off the shelf. #2 The ball receiver locks into place, but YOU must be sure to hear a "click" it makes. I did not do this correctly and lost my receiver ball, thankfully while I was not hauling anything. While this is all totally my fault, I have Never made that mistake with a standard square receiver, Ever. And remember, if you loose your ball adapter, $xxx. #3 The rubber plug that keeps the receive opening covered fell out. I'm not surprised, it faces directly down and is nearly impossible to take in and out regularly. #4 The wiring harness plug bracket that hold the plug for trailer connection is thin metal that bends with usage. It’s garbage, but it works okay. #5 Just a little inconvenient taking the hitch/chains on and off due to the hidden location, but that's not much of a con. #6 The aftermarket wiring harness failed in less than a year. I replaced it with the OEM wiring which is expensive ($xxxx), requires taking the rear bumper and interior off the car again, and also requires programing from the dealer ($xxx). #7 Cannot add a reverse wire to the aftermarket harness. Although the hitch instructions indicate I shouldn’t really ever need a 5th wire, low and behold a boat trailer I bought later on had a 5 wire plug and I could not upgrade the existing module. #8 With aftermarket wiring, the car doesn’t know you’re hauling a trailer. This is annoying when in reverse and the car constantly thinks you’re hitting something, or it signals you that there’s a car in your blind spot.

#1 Hard to see after installation, which is cosmetically appealing
#2 No receiver rattle when hauling

Now I have a stealth receiver and OEM wiring. FYI: The OEM hitch is a standard square receiver and is very well built.

Thanks for reading

The programming process should be started before the installation of the parts. Please allow at least a week to make programming arrangements. Also, the purple wire is the reverse wire which is located in the middle of the 7 way. You should not have to add any additional wires.

Fantastic fit and quality. Can’t wait for them to come out with one for my 2021 Land Rover Defender.
