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.
Experience a smoother, more controlled ride on your Harley-Davidson with Progressive 412 Series shocks. These shocks feature a double-wall steel body, nitrogen-charged internals, and multi-stage velocity-sensitive valving for consistent damping. Riders can choose between standard or heavy-duty progressive rate springs and dial in their ride with a five-position cam preload adjuster.
The Progressive 412 Series shocks are engineered to transform your Harley-Davidson's suspension, offering a significant upgrade in both comfort and control. Their robust design, coupled with advanced damping technology, ensures that your bike responds predictably to varying road conditions. Whether you're navigating city streets or carving canyons, these shocks provide the stability and feedback a performance rider demands.
With options for both standard and heavy-duty spring rates, the Progressive 412 Series shocks can be tailored to match your specific riding needs, whether you're a lighter rider or frequently carry a passenger and gear. The intuitive 5-position preload adjuster makes it simple to fine-tune your suspension for optimal performance and comfort, ensuring your Harley-Davidson is always ready for the road ahead.
What is the difference between standard and heavy-duty springs?
Standard springs are typically suited for lighter riders or solo cruising, while heavy-duty springs provide more support for heavier riders, passengers, or loaded bikes.
Can I install these shocks myself?
Many riders with basic mechanical skills can install these shocks. However, consulting a service manual for your specific model is recommended.
Will these shocks improve my bike's cornering ability?
Yes, by providing more consistent damping and better control, these shocks can improve your Harley-Davidson's stability and confidence in corners.

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.
