Progressive Suspension 444 Series Shock - 12 Inch Heavy-Duty Black - Part 444-4250B

The Progressive Suspension 444 Series Shock (Part 444-4250B) offers advanced damping technology designed to enhance your motorcycle's ride quality and handling. Featuring the innovative Frequency Sensing Technology (FST), these shocks automatically adjust damping based on the frequency of bumps encountered, providing a smoother and more controlled ride over various terrains. The deflective disc valving further optimizes damping response, ensuring stability and comfort during aggressive riding or daily commuting. An adjustable spring preload allows for quick, tool-free customization to suit different rider weights and load conditions, making it versatile for a range of applications. Included with these shocks is a progressive rate spring, which contributes to improved ride comfort and handling, especially under heavier loads or rough conditions. Being high-pressure gas charged, these shocks deliver consistent performance, reducing fade and maintaining damping characteristics over time. Slight alterations in length—either longer or shorter than stock—may affect steering response by subtly changing the head angle, so compatibility with your motorcycle's geometry should be verified prior to installation. Heavy-duty applications are recommended for bikes frequently operated at or near maximum load capacities, ensuring durability and sustained performance under demanding conditions. Before installing shocks that are not stock length, confirm that wheel travel and clearance issues such as exhaust contact, swingarm interference, or chain and tire contact are not compromised, maintaining safety and optimal functionality.
