About this product
Experience a superior ride with the Progressive Suspension 444 Series Shocks. These shocks utilize Frequency Sensing Technology (FST) to automatically adjust damping based on bump frequency, ensuring optimal comfort and control. Built for performance and durability, the 444 Series offers a significant upgrade over stock suspension.
Description
The Progressive Suspension 444 Series shocks are engineered to provide exceptional ride quality and handling. Featuring Frequency Sensing Technology (FST), these shocks intelligently adapt to varying road conditions, delivering a smooth and controlled ride. The deflective disc valving further enhances damping performance, ensuring consistent and reliable operation. Pre-load adjustments can be made by hand without the need for special tools, making it easy to fine-tune the suspension to your specific needs. The progressive-rate spring and high-pressure gas charge work together to deliver consistent performance across a wide range of conditions. Designed and manufactured in the USA with quality materials, the 444 Series shocks are a testament to superior craftsmanship and reliability. Heavy-duty models are available for motorcycles consistently operating at or near maximum load capacity.
