Progressive Suspension 444 Series Shock - 11.5 Inch Heavy-Duty Chrome (Part Number 444-4060C)

Experience enhanced ride quality with the Progressive Suspension 444 Series Shock, designed for demanding motorcycle applications. Featuring advanced Frequency Sensing Technology (FST), these shocks automatically adjust damping by sensing the frequency of bumps, providing a smoother and more controlled ride across various terrains. The deflective disc valving ensures precise damping control, while the pre-load spring can be easily adjusted by hand without special tools to fine-tune performance for different loads and riding conditions. Equipped with a progressive-rate spring and high-pressure gas charging, these shocks maintain consistent performance and durability even under heavy use.

Constructed in the USA, the 444 Series shocks are slightly longer than stock units, which can subtly modify the head angle and improve steering responsiveness. Conversely, shorter versions may cause slight steering slowdowns. Before installation, verify that your wheel travel can accommodate these length changes without clearance issues such as contact with the swingarm, exhaust system, chain or belt guards, or tires. These shocks are especially recommended for heavy-duty applications where the motorcycle operates near or at maximum load capacity more than half the time, ensuring reliable performance under demanding conditions.
