About this product
Experience a superior ride with Progressive Suspension's 444 Series Shocks. These shocks utilize Frequency Sensing Technology (FST) to automatically adjust damping based on the frequency of bumps, providing optimal comfort and control. Built with quality and performance in mind, the 444 Series will enhance your motorcycle's handling and ride quality.
Description
The Progressive Suspension 444 Series shocks are engineered to deliver a consistently smooth and controlled ride. Featuring Frequency Sensing Technology (FST), these shocks intelligently respond to varying road conditions, adjusting damping in real-time for optimal performance. The deflective disc valving further enhances ride quality, providing a plush and responsive feel. The pre-load spring is easily adjustable by hand, eliminating the need for special tools.

Important to know
Shocks slightly longer or shorter than the stock length can alter the head angle, affecting steering response. Before installing shocks that differ from the OEM length, ensure adequate wheel travel to prevent clearance issues (e.g., swingarm/axle to exhaust contact). Heavy-duty applications are recommended for motorcycles operating near maximum load capacity more than 50% of the time.
