Progressive 412 Series shocks deliver smooth, consistent damping through a double-wall steel body with nitrogen-charged, multi-staged velocity-sensitive valving. Available in standard or heavy-duty progressive rate springs with chrome or black finish, plus an adjustable five-position cam preload for light to heavy riders.
Fits Harley-Davidson models. Verify your specific model year and chassis before ordering to ensure correct application.
Standard springs work best for lighter riders; heavy-duty springs provide more support for heavier riders or two-up riding.
Yes — the 5-position cam adjuster is rider-accessible and requires no tools. Turn to dial in your preferred ride height and stiffness.
Show chrome covers are optional on select applications. Check the product listing for your specific model to confirm availability.
They automatically adjust damping based on suspension movement speed, providing smooth ride quality over bumps and consistent performance at highway speeds.
Progressive backs these shocks with their standard warranty. Contact the seller or Progressive directly for specific coverage details.

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.
