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.
The Progressive 412 Series shocks are engineered to deliver a significant suspension upgrade for Harley-Davidson riders, balancing performance and value. Their robust design ensures consistent damping across various riding conditions, transforming your bike's handling and comfort.
These 412 Series shocks feature a double-wall steel construction, built to withstand the demands of the road. Inside, a nitrogen-charged, multi-stage velocity-sensitive valving system provides smooth, consistent damping, adapting to changing road surfaces and riding styles. This combination translates to a more controlled and comfortable ride, whether you're cruising the highway or navigating twisty backroads.
Upgrading to Progressive 412 Series shocks is a straightforward way to improve your Harley's ride quality without breaking the bank. The easy-to-use cam-style preload adjuster allows you to quickly fine-tune your suspension for solo rides, two-up cruising, or loaded touring, ensuring optimal performance and comfort for every journey. These shocks are a solid foundation for any rider looking to enhance their V-twin's handling and stability.
Can I adjust these shocks for different loads?
Yes, the Progressive 412 Series shocks feature a 5-position cam-style preload adjuster, allowing you to easily set the preload for solo riding, a passenger, or loaded saddlebags.
Will these shocks improve my bike's handling?
Absolutely. The multi-stage velocity-sensitive damping and nitrogen-charged design provide more consistent control and a smoother ride, which directly translates to improved handling and stability on your Harley-Davidson.
Are these shocks difficult to install?
Installation is generally straightforward for most riders with basic mechanical knowledge. However, if you're unsure, we recommend professional installation to ensure proper setup and safety.

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.
