Progressive 444 Series shocks for Harley-Davidson use patented Frequency Sensing Technology (FST) to dynamically adjust damping as you ride, automatically responding to small bumps and large impacts for a compliant, controlled ride. Hand-adjustable preload and choice of spring rates make these shocks tunable without special tools.
Fits Harley-Davidson models. Verify your specific year and model before ordering, as Progressive offers multiple configurations for different chassis types.
FST senses bump frequency and automatically adjusts damping — the shocks compress differently for small road imperfections versus large impacts, giving you a smoother overall ride.

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.
