Progressive Suspension 444 Series Shocks - Improved Ride Quality

Upgrade your motorcycle's suspension with Progressive Suspension's 444 Series Shocks. These shocks deliver superior ride quality and handling performance. Featuring advanced Frequency Sensing Technology (FST) and deflective disc valving, the 444 Series automatically adjusts damping to provide a smooth and controlled ride, no matter the road conditions.

Description

The Progressive Suspension 444 Series shocks utilize Frequency Sensing Technology (FST) to dynamically adjust damping based on bump frequency, ensuring optimal comfort and control. The deflective disc valving further enhances the shock's ability to react to changing road conditions. Pre-load is easily adjustable by hand, eliminating the need for special tools. These shocks feature a progressive-rate spring and high-pressure gas charge for consistent performance. Built with quality materials and made in the USA, the 444 Series shocks are designed for durability and long-lasting performance. The coilover monotube design ensures efficient heat dissipation and consistent damping, even under demanding conditions. Heavy-duty applications are recommended for bikes operating near their maximum load rating over 50% of the time.

Important to know

Shocks slightly longer than stock may alter head angle slightly and provide quicker steering. Shocks slightly shorter than stock may alter head angle and provide slower steering. Before purchasing or attempting to install shocks different than OEM length, confirm your wheel travel can be altered without causing clearance issues, such as swingarm/axle to exhaust contact and chain/belt guard or tire contact.
