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 412 Series shocks deliver durable, consistent suspension performance for your Harley-Davidson motorcycle. Utilizing a nitrogen-charged, multi-stage damper design, these shocks are engineered for reliable operation and improved ride quality. The robust double-wall steel construction and a convenient 5-position preload adjuster allow you to fine-tune your ride to match your weight and preferred riding style.
Enhance your Harley-Davidson's comfort and control with the Progressive 412 Series shocks. These shocks are a direct upgrade for stock units, providing superior damping and a more planted feel on the road. The multi-stage velocity-sensitive valving reacts intelligently to bumps and dips, ensuring consistent tire contact and a smoother, more predictable ride across various road conditions.
The 412 Series shocks are a go-to choice for Harley-Davidson riders seeking a noticeable improvement in their bike's suspension. Their combination of robust build quality and user-friendly adjustability makes them suitable for everything from daily commutes to long-distance touring. For a complete suspension transformation, consider pairing these rear shocks with a Progressive front fork kit to balance your bike's handling characteristics.
What's the difference between standard and heavy-duty springs?
Standard springs suit typical riders; heavy-duty springs are stiffer and designed for heavier riders or those frequently carrying passengers and luggage, providing more support.
Can I adjust the preload myself?
Yes, the 5-position cam-style preload adjuster is designed for tool-free adjustments, allowing you to easily dial in your ride for different loads or preferences.
Will these shocks fit my specific Harley-Davidson model?
The Progressive 412 Series is available for a wide range of Harley-Davidson motorcycles. Please use our Shop by Bike tool to verify the exact fitment for your specific year and model before ordering.

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.
