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 consistent suspension performance with a durable double-wall steel body and nitrogen-charged, multi-stage velocity-sensitive valving. They're a practical upgrade for any Harley-Davidson.
Enhance your Harley-Davidson's ride with Progressive 412 Series shocks. These units are engineered to provide consistent damping and improved control, making every ride more enjoyable. The robust double-wall steel construction ensures longevity, while the nitrogen-charged design maintains performance even under demanding conditions. Upgrade your V-twin's suspension and feel the difference.
The 412 Series shocks simplify suspension tuning for your Harley-Davidson. The accessible five-position preload adjuster allows you to quickly adapt to different loads or riding styles, from solo commuting to fully loaded touring. These shocks provide a significant improvement over stock units, offering better stability and comfort for the discerning V-twin rider. The classic chrome finish adds a touch of custom style.
Can I adjust these shocks for my weight?
Yes, the 5-position cam-style preload adjuster lets you dial in the damping for various rider weights and loads, from light to heavy.
Are these shocks a direct bolt-on replacement?
These shocks are designed as a direct replacement for many Harley-Davidson models. Please confirm your specific model and year using our Shop by Bike tool to ensure proper application and fitment.
What is the benefit of progressive rate springs?
Progressive rate springs offer a softer initial travel for comfort over small bumps, and then become stiffer deeper into the travel to prevent bottoming out on larger impacts, providing a balanced ride.

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.
