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 ride quality at an accessible price point for your Harley-Davidson. Featuring durable double-wall steel construction and nitrogen-charged, multi-stage velocity-sensitive damping, these shocks are built to perform. The five-position cam preload adjuster lets you easily tune the suspension for your weight and riding style.
Upgrade your Harley-Davidson's suspension with the Progressive 412 Series shocks, designed to offer a significant improvement in ride comfort and control. These shocks are engineered to absorb road imperfections effectively, providing a smoother and more stable experience. The robust design ensures lasting performance, making them a smart investment for any rider looking to enhance their V-twin's capabilities.
The adjustability of the 412 Series shocks allows you to fine-tune your Harley's ride to perfectly match your preferences and payload. Whether you're riding solo or with a passenger, the easy-to-use preload adjuster ensures optimal sag and comfort. These shocks are an excellent foundation for riders looking to improve their bike's stance and ride dynamics, paving the way for further performance enhancements.
Can I adjust the ride feel after installation?

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.
