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 and available in standard or heavy-duty spring rates with black or chrome finish options.
Fits Harley-Davidson models. Confirm your bike's year and model with Progressive before ordering to ensure proper mounting and spring rate selection.
FST senses bump frequency and automatically adjusts damping — soft bumps get a softer response, hard hits get firmer support, all in real-time without rider input.
No — the top-mount threaded preload adjuster adjusts by hand. Simply twist the cap to fine-tune ride height and stiffness.
Standard rate suits most riders. Heavy-duty is best if you frequently carry a passenger, cargo, or weigh more than 200 lbs.
Yes — Progressive manufactures these shocks in the USA and backs them with a Limited Lifetime Warranty.
Progressive 444s fit most Harley models, but fitment varies by year and chassis. Verify your specific bike with Progressive or the retailer before purchase.

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.
