Features to know about

Clean Look Without the Bulk: Completely Hidden Hitch Design

You don’t have to give up your vehicle’s clean lines just to carry your bikes or cargo. This hitch installs behind the bumper with the cross tube fully concealed, so nothing hangs below when it’s not in use. The 2" x 2" receiver detaches without tools, leaving no visible hardware or cutouts. When removed, you can plug the opening with the included hitch cover for a factory-fresh look every day.

Stealth Hitches center block fitted with protective hitch plug to keep debris out when receiver is removed.

Easy to Attach and Remove: Quick Latching Receiver Mechanism

When it’s time to load up, the receiver connects in seconds. Just push it into the stainless steel center block until it automatically latches in place, then press the integrated lock for a secure fit. When you’re done, unlock it, turn the handle, and lift it out. The detachable design means you can store the receiver safely out of sight and avoid low clearance issues when driving without gear attached.

Strong, Rust-Resistant Build: Stainless Steel Construction

This rack receiver is built to last. The stainless steel construction and black powder coat finish fight corrosion and road wear while maintaining full strength. It meets SAE J684 safety regulations and supports up to 350 lbs of tongue weight when using accessories. The compact design doesn’t affect ground clearance or block the trunk’s foot-access sensor, keeping both performance and convenience intact.

Quick Bolt-On Setup: No Drilling or Welding Needed

Installing this hitch is straightforward thanks to the simple bolt-on design that uses existing mounting points. There’s no drilling or welding required, so you can get it installed and ready for your favorite rack or cargo platform without modifying your vehicle’s structure. It’s a clean upgrade that adds everyday utility without changing how your vehicle drives or looks.

This is a very high quality hitch system. The color printed instructions (also easily available .pdf online) are fairly clear. The detach system is very high quality and works great. I am giving 4/5 for the high price.

Tips:
I have installed this type of hitch on a 2012 VW Jetta and now a 2011 S4 Sedan. When it came to cutting the plastic bumper to gain access to the hitch assembly, just take your time and get it close. As long as you are close to the proper area you will not be able to see the cuts. On my VW I spent over an hour making sure all of my measurements were perfect and it was exact. Then I drove that VW for 2 years and you could not see any of those cuts, and this Audi one is even more hidden.

Pro's:
- Very high quality and well made materials.
- Assembly went smooth and easy. Just take your time and follow the instructions. (may have to guess at some things see CON below)

Con's
- Price (it is very expensive but very few options for this car)
- The instructions had very clear and laid out instructions for the A4/S4 and A5/S5 with color codes and all. BUT when I began working on the car the instructions/photos did NOT match my 2011 S4. My car looked much more like the A6 and in some cases did not look like any of the photos or instructions. (example: the instructions to cut the back bumper for the A/S4 were completely wrong and mine looked just like the A/S6).
- Several of the pieces came out of their protective cardboard in transit and scratched each other up.

After one year with the hitch I have no complaints. It operates and functions just like brand new and I have no issues. I only use it for a 2-bike tray style bike rack and most of the time I dont even remove the bike from the receiver, I just release the receiver from the car.

by:
When installed on my 2016 Audi S5 Cabriolet it has only 6.5 inches of ground clearance and drags on the ground whenever you go down a curb or up an incline and that’s without any bike rack attached to the car. Once installed the hitch cannot be returned to etrailer. They should have a warning on their website indicating ground clearance may be an issue.
by:
While pulling the rear bumper cover was a bit daunting the hitch installation was straight forward. My kit came with a template to mark where the access hole for the hitch needed cut. When no hitch is installed, the hitch disappears and can only be seen if you bend down or know what you are looking for. This was the clean install and look that i was after. I could not bring myself to ruin the aesthetics with a square receiver glaring at me. While not cheap, it was the right choice for me.
I've used this hitch to pull a 4x7 utility trailer and have hauled Motocyles, a large gun safe and loads of soil as well as many other things. The hitch hasn't let me down yet!

So happy that this hitch has been a reliable solution for you, Jesse. I agree with you, too. Might be a bigger price tag but the hidden hitches are just NICE! We'd love to see a photo of your install if you ever felt like sending one in :)

Fits great, works amazing on my lowered S4.

Just finished the install. The trunk threshold and bumper on the 2015 S4 are tough to get off. Just have to be patient and pull with purpose. The directions were adequate to point you in the right direction nearly all the time. Installed, the rack and mount feel robust, and I’m excited to have the 2” receiver to fit my current rack from previous SUV.

One year in, the hitch and mount are still functioning like new. Stout and sturdy enough to carry 4-bike rack and 4 bikes, and invisible when the mount is removed!

by:
Product is very well-built - Solid, heavy and very sturdy. I couldn't find a body shop near me that was willing to install it for me because none of them had ever done anything like this before. I had the right tools, so I did it myself and the installation on my 2010 Audi A4 took several hours vs the recommended 2hrs. It was my first (and last) time taking apart the rear bumper, tail lights, trunk floor and the whole shebang. But the included instructions (with pictures) were excellent and very detailed.

My Ikuram bike rack holds up to 4 bikes so it gets pretty heavy when fully loaded. It's been a year since I've installed the hitch receiver, and it's still solid after a dozen short trips to the beach, parks etc. I love that it's totally stealth when the receiver is detached.

The only negative: If you're like me, you'll permanently secure your bike rack to the detachable receiver. The problem is the bike rack + receiver combo is very heavy (easily 60+ lbs in my case). To attach the receiver, you need to aim for the hole in the cross tube UNDER the rear bumper...which you won't be able to see. Meanwhile, I also need to lift 60+ lbs to snap the receiver into place. The first few times were a struggle - took me 10-15 minutes. These days, I can do it in maybe 3-4 minutes, but there's no way my wife could do it. Detaching the receiver is a lot easier, but you need to insert a key (again, blind) to unlock it then twist a knob really hard to release the receiver. I wish I'd cut a bigger hole so my hand can more easily reach the knob.

Overall, this is worth the money spent and I'd recommend this to my friends if they are confident of the installation and/or can find a workshop to install it for them.

I have been using this product to attach a bike rack and carrying an e-bike or two. I have had Zero issues with this product on my 2014 Audi S5 in combination with a OneUp bike rack. Although I have not used this product for traditional towing purposes. The tongue weight and ground clearance were my biggest concerns, but I am happy to report I have had almost no issues so far, other than a minor issue with the cap rubber breaking to cover the lock mechanisms.
by:
Easy install, everything lined up well. Only minor issue is the hideahitch once install sticks out 6" past the bumper cover (Too long)

  • What Stealth Hitch for Bike Racks Will Work on my 2016 Audi S4?
    Hi Bill, The Stealth Hitch Hidden Rack Receiver part # 391AUDA4A5S509 is the perfect fit for your 2016 Audi S4 and is designed to be used only for bike racks or cargo carriers, not for towing. The suggested two hour install time is geared more towards a professional.

  • Option For a Bike Rack on a 2016 Audi S5 Convertible
    I have another solution for you. But we do not have any trunk mount style bike racks that work with the convertible model of the 2016 Audi S5. While it is not an ideal scenario, the only bike rack option for your 2016 Audi S5 is a hitch mounted bike rack like the Kuat Beta Bike Rack for 2 Bikes # B202-2. This rack only weighs 12.6 lbs., which is the lightest option we have, making it the easiest to take in and out. If you do not have a hitch on your S5, the only hitch we show as a confirmed...

    The Ecohitch # 306-X7324 will not work on your 2012 Audi A4 Sedan. It is confirmed to fit a 2012 Audi A4 Allroad Quattro. The Stealth Hitches Hidden Rack Receiver # 391AUDA4A5S509 is the trailer hitch you will need. The hitch has a simple, bolt-on installation with no drilling or welding required. It has a black powder coat finish which offers a superior rust protection. This trailer hitch is only for hitch-mounted accessories only. This hitch has a maximum tongue weight up to 350 pounds.

  • Comparing Trailer Hitch Options for a 2010 Audi A5 with Dual Mufflers
    There are only two trailer hitch options for a 2010 Audi A5 with Dual Muffler, the Curt Trailer Hitch Receiver part # C11188 which is a class I or the Stealth Hitches Hidden Rack Receiver part # 391AUDA4A5S509 which is a class III. The Curt has a 1-1/4" opening and the Stealth has a 2" opening. They can both be used for towing/hauling but you'll be limited by the vehicle's capacity. There are no class II options.

  • Trailer Hitch Receiver for 2014 Audi A5 With Single Muffler
    While we do have a trailer hitch receiver that fits a 2014 Audi A5, the one you referred to is not a fit for single muffler. For your Audi with a single muffler, the only hitch that fits is the Curt Trailer Hitch Receiver # C11037. This is a Class I hitch with a 1-1/4 inch receiver and will only fit the single muffler A5. I have added a link to the installation instructions as well as a link to a video install for you to check out of the Curt Trailer Hitch # C11037.

  • Does Stealth Hitch For 2011 Audi S5 Have Low Clearance
    While we haven't had a chance to install the Stealth Hitches Hidden Rack Receiver # 391AUDA4A5S509 on a 2011 Audi S5 and thus don't have the exact clearance numbers, the vehicle is naturally low to the ground at the rear, so it is possible when going over speed bumps and the like, there could be bottoming out. That said, the receiver portion of the hitch is removable, so you should remove it when not in use. As for the towing kit with the wiring, that can be purchased later on separately...

  • Correct Trailer Hitch Fit for a 2010 Audi S5
    The only trailer hitch option we offer for a 2010 Audi S5 is the Stealth Hitches Hidden Rack Receiver part # 391AUDA4A5S509. This trailer hitch is a custom fit so no drilling with hidden design so you won't see anything under the vehicle while not in use. It has the larger 2" x 2" opening for greater accessory compatibility. It's listed as a fit for all S5 sub-models and options.

  • What Is Shipping Weight And Box Size For Stealth Hitches Hidden Rack Receiver 391AUDA4A5S509?
    The shipping weight of the Stealth Hitches Hidden Rack Receiver - Custom Fit - 2" # 391AUDA4A5S509 you were looking at for your 2010 Audi A4 Sedan is 51lbs, and the dimensions of the box will more than likely be 45" x 8" x 25". The reason I say more than likely is that if you order other products with the hitch a larger box may be used to fit all of the products. I included a link to the written instructions of the # 391AUDA4A5S509 for you to take a look at.

  • Stealth Brand Trailer Hitch Fit for 2016 S5 Audi Convertible
    According to Stealth Hitch, the proper hitch for your vehicle is part # 391AUDA4A5S509. I just spoke with my Stealth Hitch representative to confirm this for you. I've linked the installation instructions for you. This hitch would be compatible with a bike rack, but not for towing purposes. If you wanted to tow with the hitch use part # 391AUDA4A5S52T. The # 391AUDQ509 hitch you'd looked at is a fit for the 2016 Q5 or SQ5, but NOT the S5.
