Progressive Suspension 444 Series Shock - 12 Inch Standard Chrome - Model 444-4061C

The Progressive Suspension 444 Series Shock Absorber 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 in response to the frequency of bumps encountered, providing a smoother and more controlled ride across various terrains. The deflective disc valving ensures precise response and durability, while the pre-load spring can be easily adjusted by hand, eliminating the need for special tools. This allows for quick customization to suit rider preferences or load conditions.
The shocks are equipped with a progressive-rate spring and are high-pressure gas charged, ensuring consistent performance and responsiveness over time. Made in the USA, these shocks are slightly longer than stock, which can subtly alter the head angle and result in quicker steering. Conversely, shocks that are slightly shorter may slow steering response, offering flexibility to customize handling characteristics. It is important to verify that your wheel travel can accommodate length modifications without causing clearance issues, such as contact with the swingarm, exhaust, chain or belt guard, or tires before installation.
Designed for heavy-duty applications, the Progressive Suspension 444 Series Shock is recommended for bikes frequently operating near maximum load capacity—over 50% of the time. This makes it an ideal upgrade for riders seeking enhanced durability, improved ride comfort, and superior handling performance in demanding riding conditions.
