Progressive 412 Series shocks deliver durable, tuneable suspension for Harley-Davidson with double-wall steel construction and nitrogen-charged damping. A five-position preload adjuster lets you dial comfort and handling for your weight and riding style, while multi-stage velocity-sensitive valving keeps the ride smooth over rough pavement.
Fits Harley-Davidson models. Consult Progressive's fitment chart to confirm application and confirm availability of chrome covers on your specific year and model.
The 5-position cam-style adjuster lets you dial preload without tools — rotate the cam to match your weight and preferences.
Standard springs suit lighter riders; heavy-duty springs are for heavier riders or two-up duty to maintain ride height and damping.
Show Chrome covers are available on select applications — check fitment compatibility with your model year before ordering.
Yes — the multi-stage damping and adjustable preload tighten suspension response and reduce wallowing compared to worn OEM shocks.

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.
