Progressive 412 Series shocks deliver reliable suspension performance with a durable double-wall steel body and nitrogen-charged, velocity-sensitive damping. Five-position preload adjustment lets you tune the ride for your weight and riding style, and available Show Chrome covers let you customize the look.
Fits Harley-Davidson models. Verify your specific year and model before ordering to ensure correct application.
Yes — the 5-position cam-style adjuster lets you dial preload up or down to match your weight and riding preferences without tools.
Heavy-duty springs support heavier riders or loaded touring bikes. Standard springs work best for typical street riders.
Show Chrome covers are optional on select applications. Check your model fitment — some applications include them, others sell them separately.
As a sealed, nitrogen-charged unit, the 412s require no routine maintenance. Replace when performance degrades over time.

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.
