Progressive Suspension 444 Series Shock - 13 inch Standard Black - Part 444-4039B

Experience enhanced ride quality with the Progressive Suspension 444 Series Shock, designed to deliver superior performance and versatility for your motorcycle. Featuring the groundbreaking Frequency Sensing Technology (FST), these shocks automatically adjust damping based on bump frequency, ensuring a smooth and controlled ride across various terrains. The deflective disc valving further contributes to responsive damping and stability, making these shocks ideal for riders seeking precise handling in diverse conditions. The pre-load spring is easily adjustable by hand without the need for special tools, allowing for quick customization to suit different loads and riding styles. Included with the shocks is a progressive-rate spring, which provides a balanced ride comfort and support, while the high-pressure gas charge maintains consistent performance over time. Constructed in the USA with high-quality materials, these shocks are slightly longer than stock models, which may influence the head angle and steering response, providing quicker steering characteristics. Conversely, shorter shocks can slow steering and alter head angle, so it’s important to verify your wheel travel compatibility before installation to prevent clearance issues such as contact with swingarm, exhaust, or chain/belt guards. These shocks are recommended for heavy-duty applications, especially for motorcycles operating at or near maximum load capacity over 50% of the time, ensuring reliability and durability under demanding conditions.
