Progressive Suspension 444 Series Shock - 11.5 Inch Heavy-Duty Black (Part #444-4060B)

444 Series Shock - 11.5" - Heavy-Duty - Black

The Progressive Suspension 444 Series Shock features innovative Frequency Sensing Technology (FST), enabling the shock to detect the frequency of bumps and automatically adjust damping for a smoother, more controlled ride. This adaptive feature ensures optimal comfort and handling across a variety of road conditions, making it a valuable upgrade for demanding riding scenarios.

Constructed with deflective disc valving and a pre-load spring that can be adjusted by hand without special tools, these shocks offer user-friendly customization. The included progressive-rate spring is high-pressure gas-charged, providing consistent performance and durability. Made in the USA, these shocks are designed for heavy-duty applications and are suitable for motorcycles operating at or near maximum load for extended periods.

Designed to slightly alter the bike’s head angle, the shocks may influence steering response—either quicker or slower depending on whether they are longer or shorter than stock. Before installation, it is recommended to verify that your wheel travel can accommodate these changes without causing clearance issues such as contact with the swingarm, exhaust, chain or belt guard, or tires. Proper fitment ensures optimal performance and safety during riding.
