Progressive Suspension 444 Series Shock - 13-inch Super-Duty Black (Part Number 444-4076B)

444 Series Shock - 13" - Super-Duty - Black

The Progressive Suspension 444 Series Shock is designed to enhance your motorcycle's ride quality with advanced features and high-performance components. Featuring the innovative Frequency Sensing Technology (FST), these shocks automatically adjust damping based on the frequency of bumps, providing a smoother and more controlled ride across various terrains. The deflective disc valving ensures consistent damping response, contributing to improved handling and rider comfort. Each shock comes with a pre-load spring that can be adjusted by hand without the need for special tools, allowing for quick customization to suit rider weight and riding style.
The shocks include a progressive-rate spring that offers a balanced ride with increased support during heavy loads or aggressive riding. They are high-pressure gas charged, which maintains performance consistency over prolonged use and under demanding conditions. Made in the USA, these shocks are designed for durability and reliability, capable of handling heavy-duty applications. Slight variations in length—either longer or shorter than stock—may alter the head angle, affecting steering response; longer shocks typically result in quicker steering, while shorter shocks may slow steering. Before installation, ensure your wheel travel can accommodate these shocks without causing clearance issues such as contact with the exhaust, chain or belt guard, or other components.
Ideal for motorcycles operating near or at maximum load capacity, the PROGRESSIVE SUSPENSION 444 Series shocks provide a significant upgrade over stock components, delivering improved handling, comfort, and durability for demanding riders. Whether for daily commuting or aggressive off-road adventures, these shocks are engineered to withstand rigorous use while maintaining optimal performance and ride quality.
