    I put the same shocks on my ’01 Dyna T Sport. Love them. So does my spouse. I also paid a couple hundred dollars less then I would have for the Harley stock shocks. Price was the biggest reason I chose the Progressive 444 series. Also Progressive’s history of making very good shocks.

    Hi, All, I just installed my black PS 444’s on my new 2014 Street Bob and they make a significant improvement on their main responsibility: shock absorption! The stock HD ones were like driving on 2 x 4s even at the softest setting and were really messing up my lower back. Big improvement. Also, I’m not a huge fan of slammed suspension so I mounted 13.5″ shocks which raised the seat about an inch over stock and improved location/position/relationship of foot, hand and butt. Plus, I got another inch of travel so the ride is much improved. Ride safe!

    How do you feel about the Progressive Monotube Cartridge for Touring front end? Have you done an installation video on them?
