Experience superior ride quality with the Progressive Suspension 444 Series Shock, designed with innovative Frequency Sensing Technology (FST) that automatically adjusts damping based on bump frequency for optimal comfort and control. Constructed with deflective disc valving, these shocks provide consistent performance across various terrains, ensuring a smooth and stable ride. The pre-load spring can be easily adjusted by hand without the need for specialized tools, allowing for quick customization to your riding preferences. Each shock includes a progressive-rate spring and is high-pressure gas charged, enhancing responsiveness and durability for demanding riding conditions.
Made in the USA, these shocks are slightly longer than stock, which may alter the head angle slightly and lead to quicker steering, or slightly shorter, possibly resulting in slower steering. Before installing shocks that differ from OEM length, verify that your wheel travel can be adjusted without causing clearance issues such as contact with the swingarm, exhaust, chain or belt guard, or tires. These shocks are recommended for heavy-duty applications, particularly for bikes operating near their maximum load capacity more than half the time, providing reliable performance under demanding conditions.
