this item is a single shock but made to look like two shocks in ad photo. Did not install because of this, as my style of riding is probably much more aggressive than average rider. I require stability and this appears to be anything but stable
So I had the suspension rebuilt on my Harley Heritage after OEM seals busted with only 6800 miles. I decided to purchase the Progressive Monotube suspension and I have to say what major difference while on a group ride. I felt the responsive and balanced compared to the original OEM suspension. The I immediately felt the wheels snugged to the pavement and while taking corners without any problems. I'm super stoked about the new suspension.
Haven?t had the chance to install yet, it looks like it will do what?s intended for, only concern I have is it looks like there a part missing if anyone can chime in and let me know from the pic. That?s why only 4 stars.
