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 consistent damping performance for Harley-Davidson cruisers through a nitrogen-charged, multistage velocity-sensitive design in a durable double-wall steel body. A five-position cam-style preload adjuster lets you tune for your riding weight and style, with options for chrome or black finish and Show Chrome covers on select models.
Upgrade your Harley-Davidson Touring, Softail, or Dyna with Progressive 412 Series shocks, engineered for superior ride quality and control. These shocks are built with a robust double-wall steel damper body, ensuring long-lasting durability and consistent performance. The high-pressure nitrogen gas charging, combined with multi-stage velocity-sensitive damping, provides a smooth and responsive ride that adapts to various road conditions and rider inputs, making every mile more enjoyable.
The 412 Series shocks offer the flexibility you need to optimize your Harley's suspension. The easy-to-use 5-position cam-style preload adjuster allows you to quickly fine-tune the spring stiffness to accommodate solo riding, two-up journeys, or when carrying extra gear. This adjustability ensures that your bike maintains its optimal handling characteristics and comfort, regardless of your load. With options for chrome or black finishes, these shocks also let you customize your bike's look while enhancing its performance.
Can I adjust the preload myself?
Yes. The 5-position cam-style adjuster is rider-adjustable, allowing you to quickly change the preload to suit your weight and riding style without the need for specialized tools.
Will these shocks fit my specific Harley-Davidson model?
These shocks are designed for a wide range of Harley-Davidson cruisers including Touring, Softail, and Dyna models. Please verify your specific model and year using our Shop by Bike tool to ensure correct mounting and spring rate selection.
What is the benefit of Show Chrome covers?
Show Chrome covers are an aesthetic option available on select models, designed to add a custom, polished look to your shocks, complementing your bike's overall style.

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.
