Progressive Suspension has focused exclusively on American V-twin suspension since 1982, and its Monotube fork cartridges and 400/970/970G shock series are among the most common upgrades on baggers and Softails. For most riders the stock rear shock is the single worst part on the bike — this is the fix.
Progressive 444 Series shocks for Harley-Davidson utilize patented Frequency Sensing Technology (FST) to dynamically adjust damping in real-time. This innovative feature ensures that your V-twin absorbs both small road imperfections and large impacts with a single, optimized setup. Combined with hand-adjustable preload and deflective disc valving, these shocks deliver a comfortable and tunable ride without requiring special tools.
Transform your Harley-Davidson's ride quality with the advanced Progressive 444 Series shocks. Designed for riders who demand superior performance and comfort, these shocks feature Frequency Sensing Technology (FST) that intelligently adapts to varying road conditions. This means you get consistent damping control and a smoother ride, whether you're cruising on smooth highways or tackling rougher terrain. Experience a new level of confidence and control on your V-twin.
The Progressive 444 Series shocks are built in the USA and designed for straightforward installation as a direct replacement for many Harley-Davidson models. Their user-friendly adjustability means you can dial in your preferred ride characteristics quickly, without fuss. Whether you're looking to enhance comfort for long tours or improve handling for spirited riding, these shocks offer a significant upgrade that makes a noticeable difference. Always confirm compatibility with your specific year and model before ordering.
What is Frequency Sensing Technology (FST) and how does it benefit my ride?
