Progressive Suspension 444 Series Shock - 12.5 Inch Standard/Heavy-Duty Black 444-4001B

The Progressive Suspension 444 Series Shock absorber, model 444-4001B, is engineered for optimal performance and ride quality on a variety of motorcycles. 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 different terrains. The deflective disc valving enhances response and stability, providing superior handling characteristics. Designed with user convenience in mind, the preload spring can be adjusted manually without the need for special tools, allowing for quick customization to rider preferences and load conditions. Each shock includes a progressive-rate spring and is high-pressure gas charged to maintain consistent performance over time, even under demanding riding conditions.
