Progressive 412 Series shocks deliver tunable suspension for Harley-Davidson with a durable double-wall steel body and nitrogen-charged, velocity-sensitive damping. A five-position preload adjuster lets you dial ride height and firmness to match your weight and riding style, while standard or heavy-duty progressive springs keep the bike planted through corners and over bumps.
Fits Harley-Davidson models. Verify your specific year and model before ordering to ensure correct spring rate and mounting pattern.
Yes. The 5-position cam adjuster lets you change preload without tools — dial it to match your weight and riding conditions.

Choose standard or heavy-duty progressive rate springs depending on your weight and desired ride comfort.

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.
