Progressive Suspension 444 Series Heavy-Duty Shock Absorber - 13 Inch Chrome, Part Number 444-4020C

Experience enhanced ride comfort and handling with the Progressive Suspension 444 Series Heavy-Duty Shock. Featuring advanced Frequency Sensing Technology (FST), these shocks automatically adjust damping based on the bump frequency, providing a smoother and more controlled ride across various terrains. The deflective disc valving ensures precise tuning for consistent performance and superior shock absorption.
Made in the USA, these shocks include a progressive-rate spring that adapts to your riding style and load conditions, offering optimal support whether you're cruising or tackling challenging off-road trails. The high-pressure gas charge further enhances performance stability and responsiveness, making these shocks ideal for demanding applications.
Adjusting preload is straightforward with a hand-operated feature that requires no special tools, allowing quick customization to suit your riding preferences. Designed to be slightly longer or shorter than stock, these shocks may influence your bike's head angle and steering response, so verifying clearance and suspension travel before installation is recommended. Heavy-duty applications are supported, making these shocks suitable for bikes operating at or near maximum load capacity over 50% of the time, ensuring durability and longevity under tough conditions.
