Progressive 444 Series shocks use patented Frequency Sensing Technology (FST) to dynamically adjust damping on the fly, automatically responding to small bumps and large hits for a consistent, comfortable ride. Hand-adjustable preload and available spring rates make these shocks tunable without special tools.
Fits Harley-Davidson models. Verify your specific year and model before ordering to confirm compatibility with this shock mount style.
FST automatically senses bump frequency and adjusts damping in real time, so small road imperfections and large potholes are handled without manual adjustment.
Yes — the top-mounted threaded preload adjuster allows hand-tuning without special tools. Twist the cap to dial in your ride height and stiffness.
444 shocks come in standard and heavy duty spring rate options. Choose based on your bike's weight and desired ride feel.
Yes — Progressive manufactures these shocks in the USA and backs them with a Limited Lifetime Warranty.
444 shocks fit Harley-Davidson motorcycles, but fitment varies by year and model. Confirm your specific bike against the part number before purchasing.

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.
