Damn . . . I'm on the fence about getting a set with 3.5 inch stretch. If 3.5's were included, it just might be enough to push me off on the side of ordering!! Oh well, maybe next time??
The best I could measure was the bottom of the fender facia on an '09 Street Glide is 3 1/4".
I didn't want to have any trouble so I went with the 3" it looks great.
Every thing here is built for Pickups and Surburbans so i didn't want to scrape driving in and out of places.
I think a 3 1/2" would have been fine too. Especially since I have went to the 13" Ultra shocks
