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 motorcycles utilize patented Frequency Sensing Technology (FST) to automatically adjust damping based on road input. This delivers a compliant ride that handles both small road imperfections and larger impacts with ease. Riders can expect improved comfort and control across varied road conditions.
These Progressive 444 Series shocks are engineered to transform your Harley-Davidson's ride quality. The Frequency Sensing Technology (FST) is a game-changer, dynamically adapting the damping in real-time. Whether you're cruising over minor road chop or bracing for a significant bump, the shocks respond intelligently, ensuring a smooth and controlled experience. This advanced valving system provides a consistent feel, making long rides more comfortable and spirited riding more predictable.
The 444 Series shocks are designed for riders who demand more from their suspension. With hand-adjustable preload, you can easily fine-tune your ride for solo runs, two-up cruising, or loaded touring. The choice of spring rates ensures that your suspension is perfectly matched to your weight and riding preferences, offering a truly custom feel. Made in the USA, these shocks are built for the long haul, providing a significant upgrade over stock units.
Do these shocks require any special tools for adjustment?
No, the preload on these Progressive 444 shocks is hand-adjustable, meaning you won't need any special tools to fine-tune your ride.
Will these shocks fit my specific Harley-Davidson model?
Progressive offers various lengths and spring rates. It is crucial to verify your specific model year and suspension configuration using our Shop by Bike tool before ordering to ensure correct fitment.
What does Frequency Sensing Technology (FST) do?

The shocks seem super nice, but they are incredibly stiff. Turns out they’re 130/200 top to bottom. Would be nice to have an option to choose your spring rate. Couldn’t find it in the description either. Have them installed on a 1998 sportster 1200 by the way. I’m about 180lbs and they don’t move at all, my friend who weighs about 260 also said they were way to firm. Hope this helps.
