What makes the damping performance consistent?

These shocks use nitrogen-charged, multi-stage velocity-sensitive valving. This advanced system ensures that the damping action adjusts smoothly to varying road conditions and speeds, providing a more controlled and comfortable ride.

How do I adjust the ride stiffness?

The shocks feature a five-position cam-style preload adjuster. You can easily change the spring preload by rotating this adjuster to match your riding weight or load, allowing you to dial in the perfect ride feel.

What is the difference between Standard and Heavy-Duty springs?

While this specific model comes with standard progressive rate springs, Progressive Suspension also offers Heavy-Duty spring options for select applications. Heavy-Duty springs are typically recommended for heavier riders or for those who frequently carry a passenger or heavy loads.

Product Details

If you're looking to give your Harley-Davidson Sportster a more comfortable and controlled ride, these Progressive 412 Series shocks are a solid option. They fit a wide range of Sportster models, including popular ones like the XL1200X Forty-Eight and XL883N Iron 883. These shocks are built to last, featuring a doublewall steel body construction that can handle the demands of the road.

Inside, they use nitrogen-charged, multi-staged velocity-sensitive valving to ensure smooth and consistent damping, which means less jarring over bumps and a more stable feel. You can also fine-tune your ride with the five-position cam-style preload adjuster, letting you set the suspension stiffness whether you're riding solo or carrying a passenger. The black finish and progressive rate springs give your bike a clean look while improving its handling.
