I regret to inform you that Audi specifically contraindicates the use of any WDH hitches. It could cause the hitch to disconnect with the trailer and everything and cause a big accident. The manual specifically calls it out. I used one for 2 trips, I'll discontinue the use. I learned for this time in another post in this forum when I was looking to fix my sagging. I didn't really wanted to believe it and went and confirmed in my manual. The guy here that mentioned was talking about an SQ5 or Q5 and I was thinking, maybe doesn't apply to a Q7. But sadly it does. So now I'm looking to electronic means to prevent sway.
Anybody wants to buy a WDH? (just half kidding :P )
I'm not here to debate whether WDH is ok or not for the Q7, but I find it funny that the "follow the manual" argument applies in some situations (ie: this one), but not others (ie: 10k mile OCI).
I'm sure this thread has been followed by some, and I suspect the WDH recommendation in the manual is due to EU regulations and Audi doing a CYA move than an actual engineering/technical reason: https://www.audiworld.com/forums/q7-...3067994/page3/
Last year I towed with the 60904 and spaces (that came with the kit). I wasn't overly impressed with the sag reduction. I felt it was safer for sure, but my ride height didn't seem to improve much. Not as much as I expected.
I had a center diff issue, Audi replaced it under warranty, but before I took the Q7 in, I removed the bags (cut them out).
Now I'm ready to install a set and it's a good opportunity to improve what I had before.
The question is, for those of you that did this, would you now go with 60905 kit instead? The 60905 is 3.5" x 9.5" and comes with spacers.
Does the 3.0" wide give any advantage over 3.5" or is height really the key?
Other option is 60902 which is 3.0" x 9.0" and buy 3rd party spacers..
I'm monitoring this thread as I'll very likely need to do something within a month or two. Who wants to be the trail blazer?
I just picked up a 2018 Q7 with no AS and I need to tow my boat once a year to the dealer for winterization. Boat is around 7200lbs on trailer. I def want to add helper air springs for that tow. I will also be watching this thread.
This month is going to be crazy busy for me but I’m hoping I can make time to get the 60905 bags installed. I crawled under with a tape measure and from top to bottom spring coils looks like almost 9” to me so should work.
I also need to get a tongue scale to see where I’m at. Camper battery box on tongue was a solid ice cube last fall so it either needs drainage or relocate inside.
I'm most likely going to do mine week of May 20th.
The only concern I have is the 9.50" plus spacers. That said, when I had the 60904 in they moved around for sure at 7.75 so maybe it's just fine and I'm over thinking it.
