Progressive 412 Series shocks deliver suspension improvement through durable double-wall steel construction and nitrogen-charged, multi-stage velocity-sensitive damping. Available in standard or heavy-duty progressive-rate springs with chrome or black finish, plus optional show chrome covers on select models.
Fits Harley-Davidson models. Verify specific year and chassis compatibility before ordering.
Yes — the 5-position cam-style preload adjuster lets you dial in preload based on your weight and riding style.
Heavy-duty springs handle larger riders or frequent two-up riding with stiffer progressive rates. Standard springs suit lighter riders.
No — show chrome covers are optional on select applications and sold separately. Check your model for availability.
Professional installation is recommended. Shock installation involves suspension work and preload tuning for optimal ride quality.

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.
