Progressive 444 Series shocks use proprietary Frequency Sensing Technology (FST) to dynamically adjust damping based on bump frequency, delivering a comfortable ride whether hitting small or large road imperfections. Hand-adjustable preload and progressive rate springs make tuning easy without special tools.
Fits Harley-Davidson models. Verify fitment with the specific year and model before ordering.
FST senses bump frequency and automatically adjusts damping — small bumps get soft damping, big hits get firm damping for balanced comfort and control.
Yes — hand-twist the top mount cap to adjust spring preload. No special tool needed.
Standard rate is ideal for two-up riding and highway cruising. Heavy duty is better for solo riding or heavier riders.
Yes — Progressive 444 Series shocks are manufactured in the USA and backed by a Limited Lifetime Warranty.
No — they bolt into stock mounting points. Verify fitment with your specific year and model before ordering.

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.
