Installed these shocks on my 02 Harley 883R and love them. My bike had the 11.5" Hugger shocks on it and it was so stiff it was like riding on a brick...the suspension didn't move. Now with these 12" Progressive shocks the suspension actually moves and works together with the front as they should. I ride alot with my wife and on the old shocks she chipped a tooth !! She loves these new shocks !! What a difference !!!
