Progressive 444 Series shocks for Harley-Davidson feature Frequency Sensing Technology (FST) that dynamically adjusts damping in real time to absorb both small and large bumps. Hand-adjustable preload, deflective disc valving, and progressive-rate springs deliver a comfortable ride without special tools.
Fits Harley-Davidson models. Available in three configurations (Standard, Heavy Duty, and Lowering). Verify your specific model year and frame style before ordering.
FST senses bump frequency and automatically adjusts damping in real time, so small bumps and large impacts are both absorbed smoothly without manual adjustment.
Yes — the top-mount threaded preload adjuster adjusts by hand with a simple twist. No special wrench or tool needed.
Yes, Progressive manufactures these shocks in the USA and backs them with a Limited Lifetime Warranty.
Standard and Heavy Duty spring rates are available. Choose based on your typical load and riding style.
No — the deflective disc valving and progressive-rate spring are tuned for Harley comfort and handling right out of the box.

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.
