PROGRESSIVE SUSPENSION 444 Series Shock - 11.5 Inch Standard Chrome Model 444-4063C

Experience superior ride quality with the PROGRESSIVE SUSPENSION 444 Series Shock, featuring advanced Frequency Sensing Technology (FST) that automatically adjusts damping based on bump frequency for a smoother ride. This innovative technology ensures optimal absorption of shocks, providing enhanced comfort and control across a variety of road conditions. The shocks come equipped with deflective disc valving, which offers precise damping control, contributing to improved handling and stability during aggressive riding or long-distance cruising. The pre-load spring is easily adjustable by hand without the need for special tools, allowing riders to fine-tune suspension settings for different loads or riding preferences seamlessly. Each shock includes a progressive-rate spring and is high-pressure gas charged, ensuring consistent performance and durability over time. Made in the USA, these shocks are designed to accommodate slightly longer or shorter lengths than stock units, which can influence steering response—longer shocks may lead to quicker steering, while shorter ones can result in slower handling. It is essential to verify that altering shock length will not interfere with wheel travel or cause clearance issues with components such as swingarm, exhaust, chain or belt guards, or tires before installation. Heavy-duty applications are recommended for motorcycles operating near their maximum load capacity over 50% of the time, ensuring longevity and reliable performance under demanding conditions.
