Progressive Suspension 444 Series Shock - 13 Inch Standard/Heavy-Duty by PROGRESSIVE SUSPENSION (Part 444-4002B)

Experience enhanced ride quality with the Progressive Suspension 444 Series Shock, designed for motorcycle enthusiasts seeking superior handling and durability. Featuring the innovative Frequency Sensing Technology (FST), these shocks automatically adjust damping based on bump frequency, ensuring a smoother ride across various terrains. The deflective disc valving provides precise control and responsiveness, while the pre-load spring can be easily adjusted by hand without the need for special tools, allowing for quick customization to rider weight and riding conditions.
Constructed with a progressive-rate spring and high-pressure gas charging, these shocks maintain consistent performance over time and under heavy loads. Made in the USA, the 444 Series shocks are engineered for durability and reliable operation. Slight variations in length—either longer or shorter than stock—may influence steering dynamics, providing quicker or slower response depending on your setup. Before installation, verify that your wheel travel can accommodate length changes without causing clearance issues such as exhaust contact, chain or belt guard interference, or tire rubbing. These shocks are particularly suited for heavy-duty applications, ideal for bikes frequently operating near maximum load capacity, ensuring stability and control under demanding conditions.
