Progressive Suspension has focused exclusively on American V-twin suspension since 1982, and its Monotube fork cartridges and 400/970/970G shock series are among the most common upgrades on baggers and Softails. For most riders the stock rear shock is the single worst part on the bike — this is the fix.
Progressive 412 Series shocks deliver enhanced suspension performance through a combination of double-wall steel construction and nitrogen-charged, multi-stage velocity-sensitive valving. These shocks are designed to provide smooth, consistent damping across varying road surfaces, significantly improving your Harley's ride quality.
For riders seeking a blend of performance and classic styling, the Progressive 412 Series shocks with a black finish are an excellent choice. They offer a tangible improvement over stock suspension, translating to better control and a more comfortable journey, whether you're navigating city streets or cruising the open highway. The robust internal components ensure reliable operation for miles to come.
The black finish of these Progressive 412 shocks adds a stealthy, custom look to your Harley-Davidson, complementing a wide range of build styles. Beyond aesthetics, the easy-to-use preload adjuster empowers you to fine-tune your ride for solo adventures or light loads, ensuring optimal performance and comfort every time you hit the road. They are a reliable upgrade for any V-twin platform.
Can I adjust the preload myself without tools?
Yes, the 5-position cam-style preload adjuster requires no special tools, allowing you to easily adjust your suspension for different loads or riding preferences.
What kind of spring rate do these shocks have?
This particular model features standard progressive rate springs, designed to offer a balanced combination of comfort and performance for everyday riding.
Will these black shocks fit my Harley-Davidson?
Progressive 412 Series shocks are manufactured for various Harley-Davidson models. Please verify application-specific fitment and spring rate on our website before ordering to ensure the correct configuration for your model.

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
