Progressive Suspension 444 Series Shock - 11.5 Inch Standard Black | Model 444-4063B

The Progressive Suspension 444 Series Shock Absorber offers advanced ride performance with innovative features designed for durability and superior handling. Featuring the all-new Frequency Sensing Technology (FST), this shock automatically adjusts damping based on the bump frequency, ensuring a smooth and controlled ride over various terrains. The deflective disc valving enhances shock response, providing stability and comfort during aggressive riding or on uneven surfaces. Equipped with a pre-load spring that is easily adjustable by hand without the need for special tools, this shock allows riders to fine-tune their suspension setup quickly and conveniently.
Built with a progressive-rate spring and high-pressure gas charging, the 444 Series Shock maintains consistent performance even under heavy loads, making it ideal for heavy-duty applications. Made in the USA, this shock features a slightly longer length than stock, which can subtly alter the head angle and offer quicker steering response. Alternatively, a shorter shock may slow steering, so it is important to verify your wheel travel and clearance to prevent contact issues with components such as the swingarm, exhaust, or tires before installation.
Designed for riders seeking enhanced handling and durability, especially under maximum load conditions, the Progressive Suspension 444 Series Shock is suitable for high-performance motorcycle applications. Proper installation and adjustment ensure optimal performance and longevity, making it a reliable upgrade for demanding riding environments.
