Progressive 444 Series shocks feature proprietary Frequency Sensing Technology (FST) that dynamically adjusts damping in real time to absorb both small and large bumps. Hand-adjustable spring preload, deflective disc valving, and a progressive rate spring deliver a comfortable ride tuned to your weight and riding style.
Fits Harley-Davidson. Verify your specific model and year with Progressive before ordering, as different Harley platforms may require different shock lengths and mounting configurations.
FST sensors detect bump frequency and automatically route oil through ports to adjust damping stiffness — small bumps stay soft, big hits get firmer support.
Yes. The top-mount threaded preload adjuster twists by hand to fine-tune spring compression for your weight and setup.
Progressive 444s fit Harley-Davidson cruisers. Contact Progressive or check the specific model compatibility chart — different platforms may need different part numbers.
Limited Lifetime Warranty covers manufacturing defects. Check Progressive's warranty terms for full details.
Standard and heavy duty spring rates let you match the shock to your weight and riding style.

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.
