Progressive 444 Series shocks for Harley-Davidson use patented Frequency Sensing Technology (FST) to automatically adjust damping based on bump severity, delivering a compliant ride on both small and large road imperfections. Hand-adjustable preload and deflective disc valving come standard, with your choice of spring rate and finish.
Fits Harley-Davidson. Verify your specific model year and suspension configuration before ordering — Progressive offers different lengths and spring rates for cruisers, touring, and dynas.
FST senses bump frequency and automatically adjusts damping oil flow through internal ports, so small bumps get soft response and big hits get firm support without manual adjustment.
Yes — the threaded top mount allows you to twist the cap by hand to dial in preload, no tools needed.
FST compensates for load changes within a range. Significant weight additions may require selecting a heavier spring rate when ordering.
Yes — Progressive 444s are street-legal replacements for stock shocks and do not require emissions or DOT compliance modifications.
Standard rate suits most stock Harley weights. Heavy duty is for riders carrying extra load (passenger, luggage, weight gain) or who prefer a firmer 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.
