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.
The Progressive 444 Series shocks for Harley-Davidson motorcycles integrate Frequency Sensing Technology (FST) to dynamically adjust damping based on bump frequency. This ensures consistent comfort and control over both small road imperfections and significant impacts. With hand-adjustable preload and options for different spring rates and finishes, these shocks allow riders to dial in their ideal setup without special tools.
Enhance the performance and comfort of your Harley-Davidson with the Progressive 444 Series shocks. These advanced shocks are engineered with Frequency Sensing Technology (FST), which intelligently adapts to changing road conditions. This means your V-twin will benefit from optimized damping whether you're navigating urban environments or cruising on open highways, providing a smoother, more stable, and confidence-inspiring ride.
The 444 Series shocks are a premium, made-in-USA upgrade designed for a wide range of Harley-Davidson models. Their intuitive design makes it simple to fine-tune your suspension to suit your personal preferences or riding conditions. Whether you're looking for improved comfort on long rides or sharper handling for aggressive cornering, these shocks deliver. Be sure to confirm your specific model and year compatibility to ensure correct fitment and optimal performance.
