Progressive 412 Series shocks for Harley-Davidson deliver smooth, consistent damping through a double-wall steel body and nitrogen-charged, multi-stage velocity-sensitive valving. A five-position cam preload adjuster lets you tune ride height and stiffness for your weight and riding style, with progressive spring rates that work harder as suspension compresses.
Fits Harley-Davidson models. Confirm your specific model year and chassis before ordering to ensure correct application.

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.
