Progressive 412 Series shocks deliver smooth, consistent damping through a nitrogen-charged, multi-stage velocity-sensitive design in a durable double-wall steel body. The five-position preload adjuster lets you tune spring rate for your weight and riding style, with options for chrome or black finishes and progressive or heavy-duty spring rates.
Fits Harley-Davidson models. Verify specific year and model compatibility before ordering, as the 412 is offered in multiple applications.
Yes. The 5-position cam-style adjuster lets you change preload without tools — dial it up for heavier loads or stiffer feel, down for lighter riders.
Progressive springs offer a softer initial ride that firms up as you compress them. Heavy-duty springs provide consistent stiffness throughout the stroke.
Standard 412 shocks have a black finish. Show chrome covers are available as optional upgrades on select applications — check fitment details.
Progressive 412s are engineered for long-term reliability. Life expectancy depends on riding conditions, maintenance, and load — but the durable steel construction handles hard use.
Shock installation varies by Harley model. Most riders have it done at a shop in 1-2 hours, or experienced DIY riders can handle it with basic tools.

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
