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 are designed to drastically improve the ride of your Harley-Davidson, featuring Frequency Sensing Technology (FST) that dynamically adjusts damping as you ride. This intelligent system responds to both small bumps and large impacts with automatic oil distribution, ensuring consistent comfort and control. These shocks offer a significant upgrade for Harley-Davidson cruisers, enhancing both performance and ride quality.
These Progressive 444 Series shocks in black are built to transform your Harley-Davidson's suspension, providing a superior ride experience. The core of their performance lies in the Frequency Sensing Technology (FST), which continuously adapts the damping to current road conditions. This means your bike will feel composed and comfortable whether you're hitting minor road imperfections or encountering significant obstacles. With hand-adjustable preload and a choice of spring rates, these shocks offer a tunable solution to match your specific riding style and load.
The 444 Series shocks are an ideal upgrade for riders looking to dial in their Harley-Davidson's suspension. The hand-adjustable preload makes it simple to fine-tune your ride for solo adventures, two-up touring, or when carrying extra gear. By offering a choice of spring rates, Progressive ensures you can match the shocks to your weight and riding demands. Whether you're on a Dyna, Softail, or Touring model, these shocks provide the adaptive performance and comfort needed to tackle any road with confidence.
What is Frequency Sensing Technology (FST) and how does it improve my ride?
FST dynamically adjusts damping based on road input, responding to both small and large bumps. This ensures a consistently comfortable and controlled ride by optimizing oil distribution in real time.
Are these shocks difficult to install on my Harley-Davidson?
While installation is generally straightforward, confirming your specific year and model before ordering is crucial to ensure proper fitment and to avoid any installation surprises. We recommend consulting a service manual or professional if unsure.
Can I adjust the firmness of these shocks?
Yes, these shocks feature hand-adjustable preload, allowing you to easily fine-tune the spring compression to match your weight, passenger, and riding preferences without needing any special tools.

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.
