Progressive 412 Series shocks deliver smooth, consistent damping through a nitrogen-charged, multi-stage velocity-sensitive design in a double-wall steel body. A five-position cam preload adjuster lets you dial in the ride for your weight, and spring options range from standard to heavy-duty with chrome or black finish.
Fits Harley-Davidson models. Verify specific model compatibility before ordering, as shock mounting and length vary by model year and frame type.
Yes — the 5-position cam preload adjuster lets you tune damping to match your weight and riding style.
Standard springs work for most riders. Heavy-Duty springs are better if you carry a passenger regularly or run extra weight.
Chrome covers are optional and purely cosmetic. They do not affect suspension performance.
These fit Harley-Davidson, but shock length and mounting differ by model. Confirm your specific year and model before purchasing.

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.
