NOT SURE ABOUT FITMENT?

Progressive 412 Series shocks deliver consistent damping performance on Harley-Davidson motorcycles using a doublewall steel body with nitrogen-charged, velocity-sensitive valving. The five-position preload adjuster lets you tune spring rate to match your weight and riding style, while progressive-rate springs smooth bumps throughout the suspension stroke.

Fitment

Fits Harley-Davidson motorcycles. Verify your specific model and year before ordering, as applications vary by chassis.

Frequently Asked Questions

Can I adjust the preload myself?

Yes — the 5-position cam-style preload adjuster lets you dial in spring tension without tools. Adjust to match your weight and cargo load.

What's the difference between standard and heavy-duty springs?

Heavy-duty springs carry higher loads and offer stiffer support for heavier riders or two-up riding with luggage. Standard springs suit lighter riders and solo cruising.

Do these come with chrome covers?

Standard 412s ship without covers. Chrome covers are available as optional accessories on select Harley models — check fitment when ordering.

How do I know which spring rate to choose?

Start with standard springs if you're under 200 lbs solo. Heavy-duty springs are better for riders over 200 lbs or frequent two-up touring with luggage.

Are these a direct bolt-on replacement?

Yes — they bolt into the factory shock mounts. No frame modifications needed. Installation typically takes 30-60 minutes per shock with basic hand tools.
