Progressive 444 Series shocks use patented Frequency Sensing Technology (FST) to dynamically adjust damping in real time as you ride over bumps, delivering a compliant ride whether hitting small chop or large obstacles. Hand-adjustable spring preload and available in standard or heavy-duty rates with black or chrome finish.
Fits Harley-Davidson models. Confirm your specific year and frame style with Progressive's fitment chart before ordering.
FST sensors detect bump frequency and automatically route oil through internal ports to adjust damping — stiff for quick impacts, soft for low-frequency sag.
Yes — the top-mounted threaded preload adjuster twists by hand to fine-tune ride height and spring tension.
Standard suits stock weight riders and two-up cruising. Heavy-duty is for heavier riders or extra cargo. Progressive can help match your weight.
Yes — 444 shocks bolt directly into your Harley's frame mounts without additional modifications or brackets.
Limited Lifetime Warranty covers manufacturer defects. Made in the USA.

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.
