Progressive 444 Series shocks for Harley-Davidson feature proprietary Frequency Sensing Technology (FST) that dynamically adjusts damping in real time as you ride over bumps. Hand-adjustable preload and available in standard or heavy-duty spring rates with chrome or black finish.
Fits Harley-Davidson models. Verify your year, engine, and suspension type before ordering to confirm correct spring rate selection.
FST automatically senses bump frequency and adjusts oil damping in real time — small bumps get a soft response, big hits get firm support for consistent comfort.
No — the threaded top mount cap twists by hand. No special tool is required.
Standard rate suits stock-height bikes with typical load. Heavy-duty is for riders carrying passengers, cargo, or who prefer a stiffer setup.
Yes — Progressive 444 Series shocks are manufactured in the USA and backed by a limited lifetime warranty.

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.
