Progressive Suspension 444 Series Shock - 13-Inch Heavy-Duty Chrome (Part #444-4051C)

Upgrade your motorcycle's performance with the Progressive Suspension 444 Series Shock, designed specifically for heavy-duty applications and superior ride quality. Featuring the innovative Frequency Sensing Technology (FST), this shock automatically adjusts damping by sensing the frequency of bumps, resulting in a smoother and more controlled ride across various terrains. The deflective disc valving ensures precise damping control, enhancing stability and handling during aggressive riding or long-distance cruising. A pre-load spring is included and can be adjusted by hand without special tools, allowing for quick customization to your load and riding style. Constructed with a high-pressure gas-charged design, the shock maintains consistent performance and durability over time, even under demanding conditions. Made in the USA, this shock combines quality craftsmanship with advanced technology to deliver long-lasting reliability. The 13-inch length slightly alters the front-end geometry, which can improve steering responsiveness; however, before installation, confirm your wheel travel can accommodate the change without clearance issues such as exhaust contact or chain/belt interference. For riders operating near or at maximum load ratings over 50% of the time, the heavy-duty construction provides the extra strength needed for demanding riding conditions. Whether you're replacing worn shocks or upgrading for performance, the Progressive Suspension 444 Series Shock offers a robust solution with easy adjustments and proven durability.
