Progressive 412 Series shocks deliver suspension tuning without the premium price tag, using a time-tested double-wall steel design with nitrogen-charged, multi-stage velocity-sensitive valving for consistent damping across varying road surfaces. A five-position cam-style preload adjuster lets you dial spring tension to match your weight and riding style.
Fits Harley-Davidson motorcycles. Refer to the Progressive website or parts catalog to verify exact year and model compatibility, as the 412 Series offers multiple applications across the Harley lineup.
Yes — the 5-position cam-style adjuster is rider-adjustable. Dial it up for heavier riders or two-up riding, down for lighter loads.
Standard 412 shocks have a steel finish. Optional full show chrome covers are available on select applications — check if your model qualifies.
Standard and Heavy-Duty progressive rate springs, both available in chrome or black finish.
The nitrogen-charged design and multi-stage damping provide smoother, more consistent suspension performance over factory shocks across a range of road conditions.

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.
