Progressive 412 Series shocks deliver smooth, consistent damping through doublewall steel construction and nitrogen-charged, multi-stage velocity-sensitive valving. A five-position preload adjuster lets you dial in ride quality for your weight, and available chrome covers add style to any Harley.
Fits Harley-Davidson models. Verify your specific year and model before ordering to confirm shock length and mounting style compatibility.
Standard springs suit average-weight riders; heavy-duty springs are tuned for heavier riders or frequent two-up riding. Choose based on your typical load.
Use the five-position cam-style adjuster on the shock body. Turning it adjusts spring preload to dial in your ride height and stiffness.
Chrome covers are optional on select Harley models. Standard shocks ship without covers; order covers separately if desired.
Standard suspension tools are needed — a spring compressor or shock service wrench. Your mechanic or shop can install them in under an hour per side.

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.
