The Progressive Suspension 444 Series Shock is engineered for superior ride quality and durability, featuring advanced Frequency Sensing Technology (FST) that automatically adjusts damping based on bump frequency for a smoother ride. This innovative technology ensures optimal comfort and handling across a variety of terrains by sensing the frequency of impacts and adjusting accordingly. Constructed with deflective disc valving, these shocks provide precise control and responsiveness, enhancing overall suspension performance. The pre-load spring is easily adjustable by hand, eliminating the need for special tools, which simplifies customization to match rider weight and riding conditions. Included is a progressive-rate spring that offers a seamless transition from soft to firm, paired with high-pressure gas charging to maintain consistent damping characteristics over time.
Designed to fit a range of applications, these shocks are slightly longer than stock units, potentially altering the head angle for quicker steering, or slightly shorter for more relaxed handling. It is important to verify that your wheel travel can be modified without causing clearance issues such as contact with the swingarm, exhaust, chain or belt guard, or tires before installation. These shocks are recommended for heavy-duty applications, especially for motorcycles that operate near or at maximum load capacity over 50% of the time. Made in the USA, the Progressive Suspension 444 Series Shock offers a reliable upgrade for riders seeking enhanced performance, durability, and ride quality in demanding conditions.
