About this product
About this product
Experience a new level of ride quality and performance with Progressive Suspension's 444 Series Shocks. These shocks are engineered to deliver superior comfort and control, whether you're cruising down the highway or tackling challenging roads. Built with quality and precision in the USA, these shocks are a reliable upgrade for your motorcycle.
Description
The 444 Series shocks feature Frequency Sensing Technology (FST), an innovative system that automatically adjusts damping based on the frequency of bumps encountered on the road. This ensures optimal ride quality in varying conditions. The deflective disc valving further enhances the shock's ability to respond to changes in the road surface, providing a smooth and controlled ride. Pre-load is easily adjusted by hand, eliminating the need for specialized tools. These shocks include a progressive-rate spring and are high-pressure gas charged for consistent performance, delivering a balanced and responsive suspension system. The heavy-duty design is recommended for bikes operating at or near maximum load rating over 50% of the time.
