Progressive 412 Series shocks deliver smooth, consistent suspension performance with a durable double-wall steel body and nitrogen-charged damping. A five-position cam-style preload adjuster lets you tune the ride for your weight, while available chrome or black finishes integrate with any Harley aesthetic.
Fits Harley-Davidson models. Verify your specific year and model with Progressive's fitment chart before ordering, as shock applications vary by frame and suspension design.
Yes — the 5-position cam-style adjuster lets you change preload to match your weight and riding style without tools.
Heavy-Duty springs support heavier loads and passengers better. Standard springs suit solo riders or lighter loads.
The base model ships without covers. Show chrome covers are available as an optional upgrade on select Harley applications.
Progressive offers multiple 412 variants for different Harley frames. Confirm your year and model on Progressive's website or contact V-Twin Bikers to match the correct part number.
Shock installation requires removing the old shocks and bolting on the new ones — a job most riders can handle with basic tools, though a shop can do it in under an hour.

I bought these for my '06 FLHR and could not be happier. I'm 6' 275 lbs so I went with the heavy duty option. Took about 30 min. to change shocks and the ride has improved considerably, took the jolt out of hitting heaves in the road.
While removing the rear wheel for some other service they just quite literally fell apart in two pieces leaving me with a garage floor full of suspension oil and one unusable shock. Spoke with their warranty rep who told me in so many words that its not their problem. Dissapointed to say the least.
So far loving these, the ride is much smoother and an awesome look. Going for the 12" was a good choice, raised it but not too much.
Just changed from my stock Harley to the 13-in and what a difference it made. Bike handles better and rides better
