The Progressive Suspension 444 Series Shock with a 13.5-inch length is engineered to enhance your motorcycle's ride quality and handling. Featuring innovative Frequency Sensing Technology (FST), these shocks automatically adjust damping based on bump frequency, providing a smoother and more controlled ride across a variety of terrains. The deflective disc valving ensures consistent performance, while the pre-load spring can be easily adjusted by hand without the need for special tools, offering quick customization for different riding conditions. Constructed with a high-pressure gas charge and a progressive-rate spring, these shocks deliver reliable support and performance even under heavy loads. Made in the USA, the 444 Series shocks are designed to be slightly longer or shorter than stock units, which can influence steering characteristics—longer shocks may provide quicker steering, while shorter shocks can result in slower steering. It is important to verify that your wheel travel and clearance are compatible before installation to avoid contact issues with the swingarm, exhaust, chain or belt guard, or tires. These shocks are recommended for heavy-duty applications, especially when the motorcycle operates at or near maximum load capacity over 50% of the time, ensuring durability and consistent handling in demanding conditions.
