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 bring durable, adjustable suspension to your Harley-Davidson. These shocks are engineered to provide consistent damping and improved ride quality across a wide range of riding conditions and loads. Riders looking to upgrade from stock or refresh their suspension will appreciate the straightforward adjustability.
The Progressive 412 Series shocks deliver consistent, controlled suspension performance for your Harley-Davidson. Built with a double-wall steel body and nitrogen-charged valving, they provide a smooth ride that absorbs road imperfections without bottoming out. Whether you're cruising solo or loaded down for a long haul, these shocks offer a noticeable improvement over factory units, enhancing both comfort and handling.
Upgrading to Progressive 412 Series shocks is a direct path to a more controlled and comfortable ride. The simple, effective design makes them a popular choice for riders who want to improve their bike's handling characteristics without complex adjustments. Pair these with a front-end suspension upgrade for a completely transformed ride experience on your Harley Touring, Softail, or Dyna.
Will these shocks change my bike's ride height?
The 5-position cam-style preload adjuster allows you to fine-tune the sag and ride height based on your weight and load, but the overall length of the shock is fixed. Confirm the specific length required for your model before ordering.
Are these shocks difficult to install?
These shocks are designed for a straightforward bolt-on installation for most Harley-Davidson models. Basic hand tools are typically sufficient, but we recommend consulting a service manual or a professional if you're unsure.
Do I need to make any other modifications after installing these shocks?
For optimal performance, it's always a good idea to check your front fork settings to ensure a balanced suspension feel. No other specific modifications are typically required for the shocks themselves.

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.
