Progressive 444 Series shocks for Harley-Davidson feature Frequency Sensing Technology (FST) that dynamically adjusts damping in real time to handle both small and large bumps with equal composure. Hand-adjustable preload and your choice of spring rate and finish make these a dialed-in, made-in-USA suspension upgrade.
Fits Harley-Davidson models. Confirm your specific year and model before ordering, as different Harley platforms use different shock mounts and lengths.
FST senses bump frequency and automatically adjusts oil flow through internal ports to match the road input, keeping the bike composed on both small ripples and large hits.
Yes—Progressive designed the 444 with a threaded top-mount adjuster you can turn by hand. No special tools or shop visit needed.
Heavy-duty springs support more weight (passenger, luggage, or heavier riders) with less sag. Standard is suitable for solo riding or lighter loads.
Yes—Progressive manufactures the 444 Series in the USA and backs them with a limited lifetime warranty.
Confirm fitment with your specific Harley model and year. Some models may reuse stock mounts; others may require brackets. Check the fitment tag or contact support.

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.
