Progressive Suspension 444 Series Shock - 12.5 inch Heavy-Duty Black (Part Number 444-4019B)

The Progressive Suspension 444 Series Shock Absorber, featuring a 12.5-inch length, is designed for demanding motorcycle applications where durability and performance are essential. Built with advanced features, this shock utilizes Frequency Sensing Technology (FST), which allows it to automatically adjust damping based on the frequency of bumps encountered during riding, resulting in a smoother and more controlled ride. The deflective disc valving further enhances damping precision, providing excellent responsiveness across a variety of terrains. The shock's pre-load spring can be easily adjusted by hand without the need for special tools, enabling quick customization to suit rider preferences and load conditions. Equipped with a progressive-rate spring and high-pressure gas charge, this shock offers consistent performance and improved handling, especially under heavy loads or aggressive riding conditions. Made in the USA, the 444 Series Shock is engineered for heavy-duty applications, making it ideal for bikes operating at or near maximum load ratings over 50% of the time.

It is important to note that shocks slightly longer or shorter than stock may alter the motorcycle’s head angle and steering characteristics. A longer shock can provide quicker steering, while a shorter shock may result in slower steering. Before installation, verify that your wheel travel can accommodate the altered length without causing clearance issues such as contact between the swingarm, axle, exhaust, chain or belt guard, or tires. Proper fitment is crucial for safety and optimal performance, especially when considering non-OEM shock lengths. This shock is suited for riders demanding heavy-duty performance and enhanced handling, ensuring durability and reliability in challenging riding conditions.

Overall, the Progressive Suspension 444 Series Shock offers a high-performance upgrade for motorcycle enthusiasts seeking a resilient, adjustable, and responsive shock absorber that can handle rigorous riding environments with ease. Its robust build and innovative damping technology make it a suitable choice for riders who require dependable shock performance and precise handling on demanding terrains or heavy loads.
