444 Series Shock - 13" - Standard - Black
Upgrade your motorcycle's performance with the Progressive Suspension 444 Series Shock, model 444-4039B, designed for optimal ride quality and durability. Crafted with advanced features, this shock absorber incorporates the innovative Frequency Sensing Technology (FST), which detects the frequency of bumps and automatically adjusts damping for a smoother ride. This intelligent feature ensures superior comfort and handling across various terrains. Made in the USA, the shock includes deflective disc valving for consistent damping response and a pre-load spring that can be adjusted by hand without special tools, allowing for quick customization to suit rider preferences. The shock is equipped with a progressive-rate spring and is high-pressure gas charged to maintain consistent performance over time, making it suitable for demanding conditions. Its length is slightly longer than stock, which may subtly alter the head angle and improve steering response, providing a more agile riding experience. Conversely, a slightly shorter version can be used to slow steering, depending on rider needs. Before installation, verify that the wheel travel can accommodate length changes without interference from components such as the swingarm, exhaust, chain or belt guard, or tires. This shock absorber is recommended for heavy-duty applications, especially for bikes operating near maximum load ratings over 50% of the time, ensuring reliable performance under stress. With its robust construction and innovative features, the Progressive Suspension 444 Series Shock enhances both ride quality and handling, making it a valuable upgrade for serious motorcycle enthusiasts seeking durability and precision.
