Progressive Harley 444 Series Shocks 12.5in - Black

The Progressive 444 Series Shocks feature a patented Frequency Sensing Technology (FST) that automatically adjusts damping based on the frequency of bumps encountered. This advanced valving system distributes oil through ports to effectively absorb impacts, whether they're small road imperfections or larger hits, leading to a more comfortable ride. These shocks are designed to fit a range of Harley-Davidson Dyna models, including the FXD Dyna Super Glide, FXDB Street Bob, and FXDWG Dyna Wide Glide, among others.

Beyond the FST, these 12.5-inch black shocks come with a top-mounted threaded preload adjuster. This allows you to fine-tune the suspension's stiffness by hand, without needing special tools, to match your riding style or load. You can choose between standard or heavy-duty spring rates, and they are built with a progressive rate spring and a deflective disc valving system for consistent performance. They are also made in the USA and come with a limited lifetime warranty, reflecting their well-built construction.

When considering these shocks, remember they are available in configurations for standard weight, heavy-duty (250+ lbs), and super heavy duty (Touring Models, 350+ lbs). Make sure to select the appropriate spring rate for your typical riding weight to get the most out of the FST technology.
