Progressive Suspension 444 Series Shock - 13.5 inch Super-Duty Black - Part Number 444-4077B

444 Series Shock - 13.5" - Super-Duty - Black

The Progressive Suspension 444 Series Shock with a 13.5-inch length is engineered for high-performance, heavy-duty riding conditions. Featuring the innovative Frequency Sensing Technology (FST), these shocks automatically adjust damping based on bump frequency to deliver a smooth and controlled ride across various terrains. This advanced feature enhances ride quality by providing superior shock absorption, making it suitable for demanding applications where consistent performance is essential. Constructed with deflective disc valving, the shocks are designed for precise control and durability, ensuring they can withstand rigorous use. The pre-load spring can be easily adjusted by hand without tools, allowing riders to fine-tune their suspension setup for optimal handling and comfort. Additionally, the shocks include a progressive-rate spring and are high-pressure gas charged, which contributes to consistent damping and responsiveness under load. Made in the USA, these shocks are suitable for bikes operating at or near maximum load ratings over 50% of the time, providing the durability needed for heavy-duty applications. It's important to note that shocks slightly longer than stock may alter the head angle, resulting in quicker steering, while shorter shocks can slow steering response. Before installation, verify that your wheel travel can accommodate shocks of different lengths without causing clearance issues with components such as the swingarm, exhaust system, chain or belt guard, or tires. Proper installation and compatibility ensure optimal ride quality and safety for your motorcycle. Designed for riders seeking durable, high-performance suspension, the Progressive Suspension 444 Series shocks are an excellent choice for enhancing your motorcycle’s handling and comfort in demanding conditions.
