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 tunable suspension performance with a durable double-wall steel body and nitrogen-charged, multi-stage velocity-sensitive damping. The 5-position cam preload adjuster lets you dial in the ride for your weight and riding style, and multiple spring and finish options fit most Harley-Davidson models. This ensures a personalized and responsive feel on the road.
Experience a significant upgrade in your Harley-Davidson's ride quality and handling with Progressive 412 Series shocks. Engineered to provide superior damping and control, these shocks transform your V-twin's performance over various road conditions. The robust construction and advanced valving ensure consistent, fade-free operation, making every mile more enjoyable and controlled.
The intuitive 5-position cam preload adjuster allows you to quickly set your Harley's suspension to match your specific needs, whether you're riding solo, two-up, or carrying extra gear. This adjustability is key to achieving optimal comfort and stability, preventing bottoming out, and enhancing your bike's overall handling characteristics. Consider a full front and rear suspension upgrade for a truly transformative riding experience.
Can I adjust these shocks to match my weight?
Yes, the 5-position cam preload adjuster lets you tune the ride for lighter or heavier riders, or for carrying passengers and gear.
Will these shocks fit my specific Harley-Davidson model?
These shocks fit many Harley-Davidson models. Please confirm your specific year and model using our Shop by Bike tool before ordering, as spring rate and mount type vary.
Are there different finish options available?
Yes, Progressive 412 Series shocks are typically available in chrome or black finish options to complement your bike's 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.
