Progressive 444 Series shocks for Harley-Davidson use Frequency Sensing Technology (FST) to dynamically adjust damping in real time, responding to small bumps and large impacts with automatic oil distribution for a smooth, controlled ride. Hand-adjustable preload, made in the USA with a Limited Lifetime Warranty.
Fits Harley-Davidson models. Confirm your specific year and model compatibility before ordering.
FST senses bump frequency and automatically adjusts internal oil ports to match the impact — small bumps get softer damping, big hits get firmer response.
Hand-adjustable preload — simply twist the top cap to fine-tune spring tension without tools.
Yes. Progressive 444 Series shocks are manufactured in the USA.
Limited Lifetime Warranty covers defects in materials and workmanship.
For best handling balance, install them as a pair. If replacing one, ensure both are set to the same preload.

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.
