Progressive Suspension 444 Series Shock - 13-Inch Super-Duty Black (Part #444-4076B)

Upgrade your motorcycle's performance with the Progressive Suspension 444 Series Shock, designed for superior durability and ride quality. Featuring advanced Frequency Sensing Technology (FST), these shocks automatically adjust damping by sensing the frequency of bumps, ensuring a smooth and controlled ride across various terrains. The deflective disc valving enhances shock responsiveness and stability, while the pre-load spring can be easily adjusted by hand without the need for special tools, allowing for quick customization based on rider weight and riding conditions. Each shock includes a progressive-rate spring and is high-pressure gas charged for consistent, reliable performance under demanding conditions.
Constructed in the USA, these shocks are slightly longer than stock, which may subtly alter the head angle and improve steering response. Conversely, shorter shocks could modify steering characteristics differently. Before installation, verify that your wheel travel can accommodate the change without interference from components such as the swingarm, exhaust, chain or belt guards, or tires. These shocks are recommended for heavy-duty applications, especially for bikes operating near maximum load ratings over 50% of the time, providing enhanced durability and performance for aggressive riding and heavy loads.
Designed to fit a 13-inch length, the Progressive Suspension 444 Series Shock is an excellent upgrade for riders seeking a combination of comfort, control, and reliability. Whether you're tackling tough off-road trails or riding on highways, these shocks deliver consistent handling and long-lasting performance, making them a trusted choice for demanding motorcycle enthusiasts.
