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.
Upgrade your Harley-Davidson's ride with Progressive 412 Series shocks. These units provide consistent damping performance through a durable double-wall steel body and nitrogen-charged, multi-stage valving. Easily tune for your weight and riding style with the five-position cam preload adjuster.
When it's time to ditch the pogo stick feel of stock Harley-Davidson suspension, the Progressive 412 Series shocks are a solid upgrade. Designed to deliver a noticeably smoother and more controlled ride, these shocks are built for the demands of the open road and aggressive riding alike. Their robust construction and advanced damping technology ensure that every mile is more comfortable and confident.
Whether you're cruising solo or loaded down for a long haul, the Progressive 412 Series shocks offer the flexibility to fine-tune your suspension. The easily accessible preload adjuster means you can quickly adapt your bike's ride characteristics without needing special tools. This makes them an ideal choice for riders looking for a performance boost that is also practical for everyday use.
Can I adjust the preload myself?
Yes, the 5-position cam-style preload adjuster is designed for easy, on-the-fly adjustments to match your weight and riding style.
Do these shocks come with different spring rates?
Progressive offers various spring rate options for the 412 Series, including standard and heavy-duty, to best suit your riding needs.
Will these shocks improve handling on my Harley-Davidson?
Yes, the consistent damping and adjustability of the 412 Series shocks are designed to significantly improve handling and ride comfort over stock units.

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.
