Progressive Suspension 444 Series Shock - 12.5 Inch Standard Chrome (Part #444-4038C)
Regular price $860.95 USD
Category:
Upgrade your motorcycle's ride quality with the Progressive Suspension 444 Series Shock, designed specifically for enhanced performance and durability. Featuring the innovative Frequency Sensing Technology (FST), these shocks automatically detect the bump frequency and adjust damping accordingly, providing a smoother ride over a variety of road conditions. The deflective disc valving ensures precise damping control, contributing to improved handling and comfort. The pre-load spring can be adjusted manually without any special tools, allowing for quick customization based on rider weight and riding style. Each shock includes a progressive-rate spring and is high-pressure gas charged, ensuring consistent performance and resistance to fade during aggressive riding.
Made in the USA, these shocks are slightly longer than stock, which may alter the head angle and enable quicker steering, or slightly shorter, potentially slowing steering response. Before installation, verify that your wheel travel accommodates these length variations to prevent clearance issues such as contact with the swingarm, exhaust, or chain/belt guard. The 444 Series Shock is especially recommended for heavy-duty applications where the bike operates at or near maximum load, over 50% of the time, ensuring reliable support and stability. Designed for riders seeking a combination of improved handling, comfort, and durability, these shocks are a premium upgrade for compatible motorcycle models seeking performance enhancements.
