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.
Enhance your Harley-Davidson's ride quality with Progressive 412 Series shocks, built for durable suspension performance. These shocks feature a robust doublewall steel body, nitrogen-charged damping, and progressive rate springs. The convenient 5-position cam preload adjuster allows you to easily fine-tune ride height and stiffness to match your weight and riding style.
The Progressive 412 Series shocks are a time-tested solution for riders seeking a reliable and comfortable suspension upgrade for their Harley-Davidson. Their classic design is backed by modern damping technology, providing a controlled and stable ride. Whether you're cruising solo or with a passenger, the ability to quickly adjust preload ensures your bike handles predictably and comfortably across various road conditions.
These 412 shocks offer a straightforward yet effective way to improve your Harley's ride. The nitrogen-charged damping helps prevent fade, ensuring consistent performance over long distances, while the progressive-rate springs provide excellent bump absorption and a plush feel. With options for standard or heavy-duty springs, you can choose the setup that best suits your typical load and riding preferences, making the 412 Series a versatile choice for any Harley-Davidson owner.
What is the benefit of nitrogen-charged damping?
Nitrogen-charged damping helps prevent cavitation and heat buildup within the shock, ensuring consistent damping performance and reducing fade, especially during extended rides.
How do I adjust the preload on these shocks?
The preload is adjusted using a 5-position cam-style adjuster, which allows you to quickly and easily change the spring stiffness and ride height to suit your load and riding style.
Are these shocks available in different finishes?
Yes, these Progressive 412 shocks are available in chrome or black finishes, with optional full Show Chrome covers on select models to match your bike's aesthetic.

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
