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 proven suspension performance for your Harley-Davidson, combining a durable build with advanced damping technology. These shocks are designed to provide a consistent and controlled ride, making them an excellent choice for riders seeking to improve their bike's handling and comfort. They are a reliable upgrade that will make a noticeable difference on the road.
Enhance your Harley-Davidson's ride with the trusted performance of Progressive 412 Series shocks. Featuring a robust double-wall steel body and high-pressure nitrogen charging, these shocks ensure consistent damping across all riding conditions. The multi-stage velocity-sensitive valving intelligently reacts to road imperfections, providing a smoother, more stable ride and reducing rider fatigue on long hauls.
The 412 Series shocks allow you to fine-tune your suspension with a convenient 5-position cam-style preload adjuster. This enables quick adjustments to accommodate different loads, whether you're riding solo, two-up, or with luggage. With options for standard or heavy-duty progressive spring rates, you can select the ideal setup for your riding style, ensuring optimal comfort and handling for every mile of your journey.

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.
