Progressive 412 Series shocks deliver consistent suspension performance for Harley-Davidson motorcycles with a time-tested design that improves ride quality for light to heavy riders. Double-wall steel construction and nitrogen-charged, multi-stage velocity-sensitive valving provide smooth damping across the suspension stroke, while a five-position preload adjuster lets you tune for your weight and riding style.
Fits Harley-Davidson models. Verify your specific model year and chassis with the manufacturer or seller before ordering, as shock fitment varies by platform.
The five-position cam-style adjuster lets you customize ride height and spring stiffness to match your weight and riding preference — dial softer for light riders, stiffer for heavier loads.
The 412 Series is designed for durability and long-term performance. Contact Progressive directly regarding service or rebuild options for your specific model.
Yes — standard 412 shocks ship in black, and chrome-finished versions are available. Optional full show chrome covers are available on select applications.
No — the 412 shocks bolt into your existing Harley suspension mounts as a direct replacement.

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.
