Progressive Suspension 444 Series Shock - 13 Inch Standard/Heavy-Duty Black 444-4002B

444 Series Shock - 13" - Standard/Heavy-Duty - Black

The Progressive Suspension 444 Series Shock with part number 444-4002B is engineered to enhance your motorcycle's ride quality through innovative features and durable construction. Featuring the all-new Frequency Sensing Technology (FST), these shocks can detect the frequency of bumps and automatically adjust damping for superior comfort and handling. This dynamic adjustment ensures a smoother ride over varied terrains, making them suitable for both everyday commuting and off-road adventures. Constructed with deflective disc valving, the shocks optimize oil flow for consistent damping performance, contributing to improved stability and rider control in diverse riding conditions.
The preload spring can be adjusted by hand without special tools, allowing for quick customization to rider weight and load. The included progressive-rate spring provides a balanced ride, absorbing shocks efficiently while maintaining stability. These shocks are high-pressure gas charged, which helps sustain consistent performance over prolonged use, reducing fade and maintaining damping characteristics. Made in the USA, the 444 Series shocks are designed to fit a range of applications, with slight variations in length that can influence steering responsiveness. Longer shocks may offer quicker steering, while shorter ones can slow steering response; it is essential to verify wheel travel clearance to avoid contact issues with swingarm, exhaust, or tires before installation. Heavy-duty applications are recommended for bikes regularly operating near maximum load capacities, ensuring durability and performance under stress. Overall, the Progressive Suspension 444 Series shocks provide a versatile upgrade that enhances ride quality, handling, and durability for your motorcycle.
