Progressive 412 Series shocks deliver consistent damping and adjustability for Harley-Davidson riders seeking durable suspension without premium pricing. Double-wall steel construction with nitrogen-charged, multi-stage velocity-sensitive valving provides smooth performance across a range of riding weights and conditions.
Fits Harley-Davidson models. Confirm your specific year and model before ordering for correct application.
Yes — the 5-position cam-style preload adjuster lets you dial in stiffness whether you're a light or heavy rider.
Heavy-Duty springs are stiffer and support more weight. Choose based on your body weight and typical riding load.
Progressive shocks are designed for durability, but check with Progressive directly about rebuild or service options for your specific model.
Standard models come without covers. Optional Show Chrome covers are available on select applications — check fitment compatibility.

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.
