I installed these on a 93 Sporty build along with rebuilding the front forks to HD. I'm 210 lbs and the HD are too stiff for me solo, just bearable two-up. I ordered the standard springs direct from Progressive and am hoping they're perfect.

Big improvement over stock shocks. Installed on 2011 FXDC. Very happy with these shocks, they look better and perform better than stock.

dmoehle

Wow wish I did this when I first bought the bike. Rides and handles fantastic !

Important Product Notes

Note: When shocks are shorter than stock, clearance must be carefully checked for potentially dangerous interference.

Note: Standard Duty shocks are for ride loads under 225 lbs., Heavy Duty shocks are for ride loads regularly over 225 lbs.
