DescriptionProgressive Suspension Series 444 Shock absorber
The PROGRESSIVE SUSPENSION Series 444 shock absorbers (manufacturer part no. 444-4076B) provide an effective compromise between comfort and road holding for touring and cruiser motorcycles. Equipped with Frequency Sensing Technology (FST), they detect frequency variations related to shocks and automatically adjust the damping to smooth out irregularities without constant rider intervention. Designed for "Super Duty" use, they combine robustness with precise road behaviour.
- Technology: Frequency Sensing Technology (FST) and deflector disc valve system
- Spring: progressive rate spring for an evolving response based on load
- Preload: manually adjustable, no special tools required
- Type: internal reservoir, high-pressure gas charge for consistent performance
- Finish: black
- Extended length: 330.00 mm (13.00")
- Manufacturing: United States
Note: a different length from OEM may alter the rake angle and steering behaviour — longer shocks may make the steering sharper, while shorter ones may slow it down. Before installation, check the travel and clearances (swingarm, exhaust, chain/belt guard, tyre). Recommended for motorcycles regularly loaded close to their maximum capacity (heavy use >50% of the time).
Brand: PROGRESSIVE SUSPENSION — Part No.: 444-4076B. Application examples: Harley-Davidson Road Glide ST, Road Glide CVO, Street Glide Ultra (models listed for reference).
