About this product
About this product
Upgrade your motorcycle's ride quality with Progressive Suspension's 444 Series shocks. These shocks are engineered for superior performance and handling, offering a smoother and more controlled riding experience for enthusiasts and professionals alike.
Description
The Progressive Suspension 444 Series shocks feature Frequency Sensing Technology (FST), allowing the shocks to automatically adjust damping based on the frequency of bumps encountered on the road. This innovative technology, combined with deflective disc valving, provides exceptional ride quality across various road conditions. The heavy-duty shocks are ideal for motorcycles operating at or near maximum load capacity over 50% of the time. Pre-load spring is easily adjusted by hand without the need for special tools. The progressive-rate spring and high-pressure gas charge ensure consistent performance and fade-free operation. These coilover monotube shocks are designed for rear mounting and offer a significant improvement over stock suspension systems.
