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 smooth, consistent suspension performance with a simple, durable design. Riders seeking proven value without unnecessary complexity will find these shocks an ideal upgrade for their Harley-Davidson.
These 412 Series shocks are engineered to perform across a wide range of rider weights, providing reliable damping for your V-twin. Built with robust materials and smart design, they offer a straightforward path to improved ride quality.
The 412 Series shocks are a direct replacement for your factory units, providing a noticeable improvement in comfort and control. Whether you're cruising solo or loaded down for a long haul, these shocks offer a solid foundation for a better ride. Consider your riding style and typical load to select the appropriate spring rate for optimal performance.
Can I adjust these shocks for different loads?
Yes, the 5-position cam-style preload adjuster allows you to easily adjust the spring tension to accommodate different rider weights and cargo loads.
Are these shocks a direct bolt-on replacement?
Progressive 412 Series shocks are designed as a direct replacement for many Harley-Davidson models. Always confirm fitment for your specific year and model using our Shop by Bike tool before ordering.
Will these shocks change the ride height?
These shocks are designed to provide improved damping and comfort. While they maintain a similar ride height to stock, the preload adjustment allows for minor tuning. Ensure you select the correct length for your bike.

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.
