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.
Achieve tuned suspension performance on your Harley-Davidson with Progressive 412 Series shocks. These units feature a durable double-wall steel body and nitrogen-charged damping for consistent control. A five-position preload adjuster lets you dial in the ride for your specific weight and riding style, while multi-stage velocity-sensitive valving keeps the suspension smooth over bumps and dips.
The Progressive 412 Series shocks are engineered to provide a significant upgrade in ride quality and handling for your Harley-Davidson. Moving beyond the limitations of stock suspension, these shocks offer consistent damping and a more controlled feel across various road conditions. Whether you're navigating rough city streets or cruising down the highway, the 412 Series helps maintain tire contact and provides a more confident ride.
With the Progressive 412 Series shocks, you gain the ability to easily customize your Harley-Davidson's suspension to suit your personal preferences. The intuitive 5-position preload adjuster allows you to quickly adjust the stiffness, ensuring optimal comfort and control whether you're riding solo, with a passenger, or carrying extra gear. This adaptability makes them a versatile choice for any rider seeking enhanced performance and comfort.

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.
