Progressive 444 Series shocks for Harley-Davidson use Frequency Sensing Technology (FST) to dynamically adjust damping based on bump frequency, delivering comfort over small and large road imperfections. Hand-adjustable preload and available spring-rate options let you dial in ride height and stiffness without special tools.
Fits Harley-Davidson motorcycles. Confirm your specific model and year compatibility with Progressive before ordering.
FST senses bump frequency and automatically adjusts damping — small bumps and large impacts get different oil flow for a smoother ride without manual adjustment.
Yes — the top-mount threaded preload adjuster twists by hand. No wrench or proprietary tool needed to fine-tune ride height.
Standard rates suit stock Harley ride height. Heavy-duty rates lower the bike slightly and suit heavier loads — choose based on your riding style and bike setup.
Yes — Progressive 444 shocks are manufactured in the USA and covered by a Limited Lifetime Warranty.
Installation requirements vary by Harley model. Consult Progressive's fitment guide or your mechanic for your specific bike.

This is my 2nd set of progressive's 444 shocks.<br />My 1st set were on my custom 2013 Harley Davidson Dyna Switchback, the 2nd set are on my 2016 Triumph Rocket 3 roadster.<br />These shocks do a fantastic job of smoothing out the bumps in the road, even with a passenger.
