Progressive 444 Series shocks use patented Frequency Sensing Technology (FST) to dynamically adjust damping in real time as you ride, absorbing both small and large bumps with a single setting. Hand-adjustable preload, progressive rate spring, and made in the USA with a limited lifetime warranty.
Fits Harley-Davidson models. Verify application with Progressive's fitment chart or contact support for your specific year and model.
FST automatically senses bump frequency and adjusts damping in real time — small bumps get soft damping, big hits get firm support without manual adjustment.
Yes. The top-mount preload adjuster twists by hand — no special tools needed. Start with factory settings and fine-tune for load and preference.
Yes — available in standard or heavy duty spring rates depending on rider weight and intended load.
Yes. These shocks are DOT-compliant for street use and carry a limited lifetime warranty.

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.
