Progressive 412 Series shocks deliver durable, adjustable suspension for Harley-Davidson motorcycles at a straightforward price point. Built with double-wall steel construction, nitrogen charging, and multi-stage velocity-sensitive damping for consistent performance across a wide range of rider weights and road conditions.
Fits Harley-Davidson motorcycles. Verify your specific model year and frame type before ordering to ensure proper fitment.
Yes — the 5-position cam-style preload adjuster lets you dial in ride height and stiffness for light, medium, or heavy riders.
Standard springs suit typical riders; heavy-duty springs support heavier riders or frequent two-up riding with stiffer spring rates.
Standard 412s ship without covers. Optional full show chrome covers are available on select applications — check the product listing for your model.
The nitrogen charging and multi-stage damping provide smoother, more consistent suspension performance than many factory shocks, especially on rough surfaces.
Yes — they bolt into your existing shock mounts. No frame modifications needed for most Harley models.

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.
