Progressive 412 Series shocks deliver proven suspension performance with a double-wall steel body and nitrogen-charged, multi-stage velocity-sensitive valving for consistent damping across the ride. The five-position cam-style preload adjuster lets you tune the ride for your weight and riding style, and they're available in chrome or black finishes with optional show chrome covers.
Fits Harley-Davidson models. Confirm your specific year and model for correct application and spring rate selection.
Yes. The 5-position cam preload adjuster lets you dial in comfort for your weight and riding conditions without tools.
Standard and Heavy-Duty progressive rate springs are both available. Choose based on your total riding weight.
Yes — in chrome, black, or with optional full show chrome covers depending on your bike model.
High-pressure gas keeps the shocks from fading under heat, while multi-stage valving adapts damping to different bump speeds for smooth, consistent control.

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.
