Experience superior ride quality with the Progressive Suspension 444 Series Shock, designed specifically for demanding motorcycle applications. Featuring innovative Frequency Sensing Technology (FST), these shocks automatically adjust damping in response to bump frequencies, ensuring a smoother ride over varied terrains. The deflective disc valving system enhances shock responsiveness and durability, providing consistent performance even under heavy loads. A pre-load spring, adjustable by hand without tools, allows for quick customization to suit rider preferences and riding conditions. The shocks include a progressive-rate spring and are high-pressure gas charged, delivering reliable damping performance for both street and off-road riding. Made in the USA, these shocks are engineered to withstand tough conditions, making them ideal for heavy-duty applications or motorcycles operating at or near maximum load ratings over 50% of the time. Please note that shocks slightly longer than stock may alter the head angle slightly and improve steering response, while shorter shocks may result in slower steering. Before installation, verify that your wheel travel can accommodate the shock length without causing clearance issues with components such as the swingarm, exhaust, chain or belt guard, or tires. Proper selection ensures optimal handling and safety during your rides.
