Progressive 444 Series shocks use patented Frequency Sensing Technology (FST) to dynamically adjust damping in real time, responding to both small bumps and large hits with appropriate oil flow for a composed ride. Hand-adjustable preload, available in standard or heavy-duty spring rates, and made in the USA with a limited lifetime warranty.
Fits Harley-Davidson models. Confirm your specific year and model before ordering, as shock lengths vary by chassis.
FST allows the shock to sense bump frequency and automatically adjust internal oil ports to provide the right damping — stiff for small bumps, softer for big hits — without rider input.
No. Progressive 444s feature a hand-adjustable top-mount preload cap that twists by hand — no tools required.
Heavy-duty rates support heavier loads and stiffer suspension tuning. Standard rates suit most riders. Choose based on your bike's load and riding preference.
Yes — Progressive 444 shocks are street-legal suspension components. Check local regulations if your area has specific suspension rules.
Limited Lifetime Warranty covering defects in materials and workmanship for the original owner.

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.
