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 reliable suspension performance with a durable double-wall steel body. These shocks feature nitrogen-charged, velocity-sensitive damping for a consistent and controlled ride.
A five-position preload adjustment lets you tune the ride for your weight and riding style, ensuring optimal comfort and handling. With available Show Chrome covers, you can also customize the look to match your bike's aesthetic.
The 412 Series shocks are a straightforward upgrade for any Harley-Davidson rider looking to improve their bike's handling and comfort. The ability to adjust preload quickly means you can adapt your suspension to different riding conditions, from solo cruising to two-up touring. Always verify your specific year and model using our Shop by Bike tool to ensure correct application before ordering.
Can I adjust the preload myself?
Yes, the 5-position cam-style adjuster lets you dial preload up or down to match your weight and riding preferences without requiring specialized tools.
What spring rates are available?
These shocks are available with progressive or heavy-duty spring rates, allowing you to choose the ideal setup for your riding style and anticipated loads.
Are Show Chrome covers included?
Show Chrome covers are an optional accessory available on select models, allowing you to further customize the aesthetic of your Progressive 412 Series shocks.

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.
