Progressive 444 Series shocks use Frequency Sensing Technology (FST) to dynamically adjust damping based on bump size, delivering a controlled ride over both small and large road imperfections. Hand-adjustable preload and deflective disc valving allow tuning without special tools, and all shocks are made in the USA with a Limited Lifetime Warranty.
Fits Harley-Davidson models. Verify year and model compatibility with Progressive before ordering, as fitment varies by chassis and suspension type.
FST senses bump frequency and automatically adjusts internal oil flow through ports to dampen small bumps smoothly while controlling larger impacts.
Yes — the top-mount threaded adjuster allows hand-tuning of spring preload without special tools.
Heavy duty springs provide firmer support for two-up riding or heavier loads. Standard springs are tuned for solo riding.
Limited Lifetime Warranty covers defects in materials and workmanship for the original owner.
Progressive 444 shocks are manufactured in the USA.

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.
