Progressive 412 Series shocks deliver a smooth, consistent ride through double-wall steel construction and nitrogen-charged, multi-stage velocity-sensitive valving. A five-position cam-style preload adjuster lets you dial in compression for light or heavy riders, making these a versatile upgrade for Harley-Davidson suspension.
Fits Harley-Davidson motorcycles. Confirm your specific model and year before ordering, as shock mounting points and geometry vary by platform.
Yes — the 5-position cam-style preload adjuster is user-friendly and requires no special tools.
Base 412 shocks ship without covers, but optional Show Chrome covers are available on select applications.
Standard springs suit lighter riders, while heavy-duty springs provide more support for heavier riders or loaded touring.
Progressive 412 shocks are sealed units. For long-term service, contact Progressive about their rebuild program or warranty.

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.
