Progressive Suspension 444 Series Shock - 12 inch Standard Black (Part #444-4249B)

444 Series Shock - 12" - Standard - Black

The Progressive Suspension 444 Series Shock with a 12-inch length offers advanced damping capabilities designed to enhance your motorcycle's ride quality. Featuring the innovative Frequency Sensing Technology (FST), these shocks automatically adjust damping in real-time by sensing bump frequencies, ensuring a smoother and more controlled ride across various terrains. The deflective disc valving provides precise shock response, improving comfort and handling during both casual and aggressive riding. The shocks include a progressive rate spring that adapts to riding conditions, delivering a balance of comfort and stability.

These shocks are high-pressure gas charged to maintain consistent performance over time, reducing fade and ensuring reliable damping. They also allow for easy manual adjustment of spring pre-load without the need for special tools, enabling quick tuning to match rider preferences or load changes. Slight variations in length, either longer or shorter than stock, can influence the motorcycle’s steering characteristics by subtly altering the head angle, providing options for quicker or slower steering responses.

Heavy-duty applications are recommended for bikes operated at or near the maximum load capacity over 50% of the time, ensuring durability and performance under demanding conditions. Before installing shocks that differ from the OEM length, it is important to verify that wheel travel and clearance are adequate to prevent contact with exhaust components, chain or belt guards, or tires. Proper installation and compatibility will help maximize the benefits of these shocks, delivering a superior riding experience with enhanced control and comfort.
