Description
If you’re running your bike hard and demanding consistent performance across varying terrain, the Progressive 444 Series Shock delivers the precision damping control you need without constant manual adjustments. Frequency Sensing Technology automatically adapts to bump inputs in real-time, eliminating the guesswork of traditional fixed-valving shocks and keeping your suspension working optimally whether you’re cruising or pushing limits. Built for longevity and heavy-duty applications, these shocks combine high-pressure gas charging with progressive-rate springs to maintain performance even when your bike is operating at or near maximum load capacity.
