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.
The Progressive 412 Series shocks deliver smooth, consistent damping, significantly improving the ride quality of your Harley-Davidson. Engineered with a durable double-wall steel body and nitrogen-charged valving, they offer enhanced control and comfort.
These 412 Series shocks are built for the long haul, featuring a robust double-wall steel damper construction. The high-pressure nitrogen gas charging and multi-stage velocity-sensitive damping work in harmony to provide a responsive and controlled ride, smoothing out bumps and maintaining tire contact with the road. This translates to less fatigue on long rides and more confidence when pushing through corners.
One of the key advantages of the Progressive 412 Series is its adaptability. The 5-position cam-style preload adjuster allows you to effortlessly dial in the perfect firmness for your weight and riding style, whether you're riding solo, with a passenger, or fully loaded for a trip. This means you can optimize your Harley's suspension without the need for complex tools or swapping out components.
Can I adjust the ride comfort without replacing the shocks?
Yes, the 5-position cam-style preload adjuster lets you dial in firmness for your weight and riding style, allowing for quick adjustments to ride comfort.
What makes the 412 Series durable?
The 412 Series shocks feature a double-wall steel damper body combined with high-pressure nitrogen charging, which contributes to their robust construction and long-term durability.
Will these shocks fit my specific Harley-Davidson model?

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.
