Progressive Suspension 444 Series Shock - 13.5 inches, Standard/Heavy-Duty, Chrome - Part 444-4003C

The Progressive Suspension 444 Series Shock Absorber combines advanced technology with durable construction to enhance your motorcycle's ride quality. Featuring the innovative Frequency Sensing Technology (FST), these shocks automatically adjust damping based on the frequency of bumps, providing a smoother and more controlled ride over various terrains. The deflective disc valving design further improves damping consistency, ensuring predictable handling and stability during aggressive riding or long-distance cruising.
Each shock includes a pre-load spring that adjusts easily by hand without the need for special tools, allowing for quick customization based on rider weight and riding conditions. The shocks are equipped with a high-pressure gas charge and a progressive-rate spring, which work together to deliver consistent performance, better shock absorption, and improved handling. Made in the USA, these shocks are built to withstand rigorous use and demanding applications.
Note that shocks slightly longer than stock may alter the head angle slightly, leading to quicker steering response, while shorter shocks could result in slower steering. Before installation, verify that your wheel travel can be modified without causing clearance issues such as contact with the swingarm, exhaust, chain or belt guards, or tires. These shocks are recommended for heavy-duty applications, especially for bikes operating at or near maximum load ratings over 50% of the time, providing reliable performance in demanding conditions.
