The Progressive Suspension 444 Series Shock absorber is engineered for superior performance and durability, featuring advanced Frequency Sensing Technology (FST) that detects bump frequency and automatically adjusts damping for optimal ride comfort and handling. This innovative technology ensures a smooth ride across various terrains by dynamically adapting to road conditions, providing better control and rider confidence. The shock includes deflective disc valving for consistent damping performance and a pre-load spring that can be adjusted manually without any special tools, allowing for easy customization to your riding preferences.
The 444 Series Shock is equipped with a progressive-rate spring and is high-pressure gas charged, ensuring reliable and consistent performance over extended use. Its design slightly alters the stock length, which may influence the head angle and steering response—shorter shocks tend to slow steering, while longer shocks can enhance responsiveness. It’s essential to verify that your wheel travel can accommodate these modifications without causing clearance issues, such as contact with exhaust, chain or belt guards, or tires, especially when considering shocks that differ from OEM length.
Constructed in the USA with high-quality materials, this shock absorber is recommended for heavy-duty applications, particularly for bikes operating at or near maximum load ratings over 50% of the time. Whether you ride on rugged trails or city streets, the Progressive Suspension 444 Series Shock provides improved ride quality, enhanced handling, and long-lasting durability, making it an excellent upgrade for your motorcycle’s suspension system.
