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

The 5-position cam-style preload adjuster allows you to fine-tune the suspension's stiffness. This means you can adjust the ride to better suit your weight, riding style, or whether you are carrying a passenger or cargo.

Are these shocks nitrogen charged?

Yes, these shocks are nitrogen charged. This helps to maintain consistent damping performance by preventing oil and gas from mixing, especially under demanding conditions.

What kind of springs do these shocks use?

These shocks come with progressive rate springs. Progressive springs offer a softer initial feel that stiffens up as they are compressed, providing a balance of comfort and control.

Product Details

Starting with a doublewall steel body construction, these Progressive 412 Series shocks are built to last. They offer a significant improvement over stock suspension performance for a wide range of Harley-Davidson motorcycles, including models like the Dyna Super Glide, Street Bob, and Fat Bob. The nitrogen-charged, multi-staged velocity-sensitive valving works to provide smooth and consistent damping, helping to absorb road imperfections more effectively.

You can fine-tune your ride with the five-position cam-style preload adjuster. This lets you dial in the suspension whether you're carrying a light load or a heavier one, ensuring a more comfortable and controlled experience. These shocks come with progressive rate springs in a black finish, and are available in standard or heavy-duty options for select applications, giving you choices to match your riding style and needs.
