Frequently Asked Questions
Can I adjust the ride height or stiffness?
Yes — the 5-position cam-style preload adjuster lets you dial in firmness without changing springs. Rotate the collar at the top of each shock to adjust.
Do these come with chrome covers?
Standard 412s ship bare. Optional full show chrome covers are available on select Harley applications — check fitment details for your model.
What's the difference between Standard and Heavy-Duty springs?
Heavy-Duty springs support more weight and offer a firmer baseline. Choose Standard for light riders or Heavy-Duty if you regularly carry a passenger or load.
Are these street-legal?
Yes. Progressive 412s meet standard suspension performance requirements for street use on Harley-Davidson motorcycles.

Stiff
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.
