Progressive 444 Series shocks for Harley-Davidson use proprietary Frequency Sensing Technology (FST) to dynamically adjust damping on the fly, responding to small bumps and large hits with automatic oil flow compensation. Hand-adjustable spring preload and available in standard or heavy-duty rates with black or chrome finish.
Fits Harley-Davidson models. Verify application with Progressive's fitment chart or contact tech support for your specific year and model.
FST senses bump frequency and automatically adjusts internal damping oil flow to absorb both small road chatter and large impacts without manual adjustment.
Yes — the top-mount threaded adjuster lets you fine-tune preload by hand with no special tools needed.
Standard rate works for solo riders and stock weight; heavy-duty is for riders who carry passengers, luggage, or heavier body weight.
Yes, Progressive 444 shocks are manufactured in the USA.
Installation typically requires basic tools and knowledge of shock removal/installation. Consult the manual or a qualified mechanic if unsure.

The shocks seem super nice, but they are incredibly stiff. Turns out they’re 130/200 top to bottom. Would be nice to have an option to choose your spring rate. Couldn’t find it in the description either. Have them installed on a 1998 sportster 1200 by the way. I’m about 180lbs and they don’t move at all, my friend who weighs about 260 also said they were way to firm. Hope this helps.
