About This Product
The Progressive Suspension 444 series takes rear suspension to the next level with their Frequency Sensing Technology. This allows the shocks to dynamically adjust damping based on the road surface, providing a smooth ride over small bumps while maintaining control through the big hits. Sold as a set, these 13.5-inch heavy-duty shocks are finished in black and feature a threaded top mount for easy, tool-free hand adjustment of the spring preload. These are heavy-duty units, ideal for riders who spend most of their time riding two-up or fully loaded with gear. They are designed to fit 1980–2008 FLT and Touring models, offering a significant performance boost and a much more controlled ride than standard shocks.
Manufacturer part number: 444-4021B.
