Progressive Suspension 444 Series Shock - 12.5-Inch Standard Chrome (Part #444-4038C)

The Progressive Suspension 444 Series Shock provides exceptional performance and ride quality, featuring innovative Frequency Sensing Technology (FST) that automatically adjusts damping based on bump frequency for a smoother ride. This advanced technology ensures optimized damping response, improving comfort and handling across a variety of terrains. Constructed with deflective disc valving, these shocks deliver precise control and consistent performance under demanding conditions. The pre-load spring is easily adjustable by hand, eliminating the need for special tools and allowing quick customization for optimal ride height and firmness.
Made in the USA, these shocks include a progressive-rate spring designed to adapt to different loads and riding styles, providing a balance of comfort and support. They are high-pressure gas charged to maintain consistent damping performance over time. The slightly longer design compared to stock shocks may subtly alter the head angle, resulting in quicker steering response, while shorter variants can provide a slower steering feel, allowing for tailored handling characteristics. It is important to verify that wheel travel and clearance are suitable for your specific motorcycle setup before installation, as modifications to length can impact swingarm, axle, exhaust, chain or belt guard, and tire contact.
These shocks are highly recommended for heavy-duty applications where the bike operates at or near maximum load for over 50% of the time. Their robust construction and advanced features make them suitable for riders seeking improved durability, control, and ride quality on demanding rides or heavy loads. Whether upgrading your stock suspension or customizing for specific riding conditions, the Progressive Suspension 444 Series shocks offer a reliable solution for enhanced motorcycle performance.
