Progressive 444 Series shocks for Harley-Davidson use patented Frequency Sensing Technology (FST) to dynamically adjust damping in real time, absorbing both small and large bumps with a single setup. Hand-adjustable preload and deflective disc valving deliver a comfortable, tunable ride without special tools.
Fits Harley-Davidson models. Confirm your specific year and model compatibility with Progressive before ordering.
FST senses bump frequency and automatically adjusts internal oil ports to dial in the right damping — soft bumps get soft compression, hard hits get firm support.
No — the top-mount preload adjuster is a simple hand-twisted cap. No wrench or spring compressor needed.
Yes — available in black or chrome finish depending on configuration.
Limited Lifetime Warranty. Shocks are made in the USA by Progressive.
Standard and heavy duty spring rates — choose based on your bike's suspension setup and riding style.

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.
