Category:
The Progressive Suspension 444 Series Shock with a 13.5-inch length is engineered for heavy-duty motorcycle applications, providing enhanced stability and control under demanding conditions. Featuring the innovative Frequency Sensing Technology (FST), these shocks automatically adjust damping based on the frequency of bumps encountered, resulting in a smoother ride and superior handling. The deflective disc valving design ensures consistent shock performance across various terrains, while the preload spring can be easily adjusted by hand without requiring special tools, allowing for quick customization based on rider weight and riding style. These shocks include a progressive-rate spring and are high-pressure gas charged, which maintains consistent damping characteristics and improves ride comfort even under heavy loads. Made in the USA, they are designed to withstand rigorous use and provide reliable performance over time.
