Features to know about

Clean Look Without the Bulk: Completely Hidden Hitch Design

No one wants to ruin the lines of their vehicle with a bulky hitch hanging below the bumper. This setup keeps everything tucked away. The cross tube stays hidden behind the bumper, and both the 2" receiver and ball mount detach completely with no tools when you’re done towing or hauling. You get a clean, from-the-factory look that doesn’t affect ground clearance or block any foot-activated sensors.

Quick Swaps Between Towing and Carrying: Removable Attachments

Switching from towing to carrying gear couldn’t be simpler. The center block’s tight-tolerance design lets you pop in either the included ball mount for a small trailer or the included receiver for a bike rack or cargo carrier. Just latch it in place, press the integrated lock to secure it, and you’re ready to go. When you’re finished, unlock it, remove the attachment, and cover the opening with the hitch plug to keep out dirt and debris.

Strong, Safe, and Built for Real Use: Stainless Steel Construction

This hitch is made from durable stainless steel that resists corrosion and meets SAE J684 towing safety regulations. It’s rated for up to 3,500 lbs gross trailer weight and 350 lbs tongue weight when using the included 2" ball mount attachment. The sturdy center block design keeps movement to a minimum when starting or stopping, so your trailer or rack stays stable mile after mile.

Simple Setup That Protects Your Vehicle: Bolt-On Install and Included Wiring

You don’t need to drill or weld anything to get this hitch installed—it bolts right up using existing connection points that preserve your vehicle’s crumple zones. The included 4-way flat connector powers your trailer’s signal lights and connects directly to the battery to avoid overloading the electrical system. A magnetic clip keeps the connector secured near the hitch when not in use, ready for your next haul.

2023 Audi A5
The stealth hitch with towing package has been a rock solid product that is well made and seamlessly integrated into my Audi A5. I had a professional install it and they did a good job. No computer reprogramming was needed for the light system.

They noted it was more difficult than they were expecting and took closer to 3-4 hours so certainly DIY-able with the right tools, but expect it will take a bit of time. Make sure you cut a big enough opening in the bottom of the bumper as the access to the latch key, release, and electrical will all be done through that hole you cut as the hitch sits so far up and hidden.

  • Should Factory Bumper Beam be Reinstalled for 2024 Audi S5 Stealth Hitches Installation
    Hey Jim, If you have room to reinstall the factory reinforcement beam on your 2024 Audi S5 and fit the Stealth Hitches Hidden Trailer Hitch Receiver # 391AUDA5S518T then by all means go for it. Usually when the instructions say to discard the beam that means there physically isn't room, but every once in a while, we find that there is a little wiggle room so we add it back in just because it won't hurt anything. Since trailer hitches are stiff pieces of metal they are good substitutes...

    Installing the Stealth Hitches Hidden Trailer Hitch Receiver w/ Towing Kit # 391AUDA5S518T on your 2021 Audi A5 will not void your manufacturers warranty.
