Improvement over previous shocks
Installed these on my 91’ fxr and I’m very pleased. I considered a higher quality set of shocks but couldn’t bring myself to spend $600+ on Harley shocks. Bike feels much more planted everywhere. These 14.25” shocks set my bike almost perfectly level. Frame is almost parallel with ground. Just barley higher in front which I think is perfect.

These shocks made an amazing improvement to my 2014 Sportsters ride quality and handling!!!
What a huge difference in ride quality!!! I installed these on my 2014 HD Iron (XL883N), even though Amazon says they wont fit, they do. They have made the height and ride many times better than I could have expected. I paired these shocks with the Progressive 18.5" fork springs and the bike is now a whole different animal, I can actually lean in and corner aggressively now! I'll probably have to upgrade my tires and brakes now to keep up with how much of an improvement the Progressive shocks and springs made!

Best Bang for your Buck!
Great shocks for my 1990 FXRS. Corner well, comfortable 2 up and super easy to install.If you’re like me and not interested in paying a mortgage payment for a set of shocks, these are quality shocks that do the job well.

Great upgrade for FXRP
Install was fairly straight forward. Installed on 92 FXRP. Replaced chrome 12” shocks, possible originals. Ride and handling are amazing-not sure if that’s because the old ones were shot or these are so good! But no complaints
