The Progressive Suspension 444 Series Shock absorber offers advanced technology and durable construction designed for demanding motorcycle applications. Featuring the all-new Frequency Sensing Technology (FST), these shocks automatically adjust damping in real-time based on the frequency of bumps encountered, ensuring a smoother and more controlled ride across varied terrains. The deflective disc valving enhances responsiveness and consistency, contributing to improved handling and rider comfort. With pre-load spring adjustment that can be easily modified by hand without special tools, riders can fine-tune their suspension setup to match their riding style and load conditions. Included is a progressive-rate spring complemented by high-pressure gas charging, which maintains consistent performance and durability under heavy-duty use.
Made in the USA, these shocks are slightly longer than stock units, which can influence the head angle and steering characteristics—potentially offering quicker or slower steering depending on the specific installation. It is essential to verify that alterations in wheel travel do not cause clearance issues with components such as the swingarm, exhaust, chain or belt guard, and tires before installation. The 444-4020B shocks are recommended for heavy-duty applications, especially for bikes operating at or near maximum load ratings over 50% of the time. Their robust construction and sophisticated damping technology make them ideal for riders seeking enhanced performance, stability, and ride quality under demanding conditions.
Designed for professional and enthusiast use alike, the Progressive Suspension 444 Series Shock provides reliable, high-performance suspension upgrade for a variety of motorcycle models. Whether used for daily commuting or aggressive off-road riding, these shocks deliver superior damping, improved control, and increased durability, ensuring a confident riding experience in challenging environments.
