Progressive 412 Series shocks deliver consistent damping performance for Harley-Davidson motorcycles through a durable double-wall steel design. High-pressure nitrogen charging and multi-stage velocity-sensitive valving provide smooth suspension feel across road conditions, while a five-position preload adjuster lets you tune for your weight and riding style.
Fits Harley-Davidson motorcycles. Check fitment notes for your specific model year and application before ordering.
The 5-position cam-style adjuster lets you dial preload up or down. Clockwise increases preload for heavier riders; counterclockwise decreases it for lighter weight.
Heavy-Duty springs carry more load and suit heavier riders or two-up duty. Standard springs work best for solo and light-rider applications.
Nitrogen gas prevents damping fluid foaming under heat and compression, maintaining consistent shock performance across temperature and riding intensity.
Yes — Select models offer optional full Show Chrome covers. Verify your Harley model is available for chrome cover fitment.

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
