PROGRESSIVE SUSPENSION 444 Series Shock - 12 inch Heavy-Duty Black (Part #444-4058B)

444 Series Shock - 12" - Heavy-Duty - Black

The PROGRESSIVE SUSPENSION 444 Series Shock with a 12-inch length is engineered for heavy-duty motorcycle applications, providing exceptional ride quality and durability. Featuring innovative Frequency Sensing Technology (FST), these shocks automatically adjust damping based on the frequency of bumps encountered, ensuring a smooth and controlled ride across varying terrain. The deflective disc valving further enhances damping precision, contributing to improved handling and rider comfort. Equipped with a pre-load spring that can be independently adjusted by hand without tools, these shocks allow for easy customization to suit rider weight and riding conditions. The included progressive-rate spring is designed to provide consistent performance under heavy loads, and the high-pressure gas charge ensures reliable operation over time. Made in the USA, these shocks are slightly longer than stock, which may alter the head angle for quicker steering, or slightly shorter, potentially slowing steering response, depending on your setup. It is important to verify that your wheel travel can be safely altered without causing clearance issues, such as contact with the exhaust, chain or belt guard, or tires. These shocks are recommended for heavy-duty applications, especially for bikes operating at or near maximum load ratings more than half the time, offering durability and superior performance for demanding riding conditions.
