Progressive 412 Series shocks deliver durable, adjustable suspension for Harley-Davidson with a proven design that improves ride quality across a wide range of rider weights. Double-wall steel bodies house nitrogen-charged, multi-stage velocity-sensitive damping that maintains consistent performance mile after mile.
Fits Harley-Davidson models. Verify your specific model year and application before ordering, as shock length and mounting style vary.
Yes. The 5-position cam-style preload adjuster lets you dial in spring stiffness to match your weight and riding style without tools.
Heavy-duty springs support heavier riders or carrying loads. Standard springs work best for lighter riders. Choose based on your weight and typical luggage load.
Standard models ship without covers. Show Chrome covers are optional on select applications — check your fitment details.
Nitrogen prevents damping fluid from foaming under hard compression, keeping damping consistent and preventing shock fade during long rides.

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.
