What is the main benefit of the 5-position preload adjuster?

The 5-position cam-style preload adjuster lets you easily dial in your suspension. You can adjust it to better suit your weight and riding conditions, whether you're riding solo or with a passenger.

What makes the damping performance consistent?

These shocks use nitrogen-charged, multi-stage velocity sensitive valving. This system helps maintain consistent damping across a variety of speeds and road conditions, providing a smoother ride.

Are these shocks a direct replacement for my stock Harley shocks?

Yes, these 12.0 inch shocks are designed as a direct fit for many Harley-Davidson models. Always verify the fitment list to ensure compatibility with your specific motorcycle year and model.
