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

The five-position cam-style preload adjuster allows you to easily fine-tune the suspension's firmness. This means you can adjust the ride to better suit your weight, riding style, or if you're carrying a passenger or cargo.

Are these shocks filled with gas?

Yes, these shocks are high-pressure gas charged. This helps maintain consistent damping performance by preventing oil cavitation and ensuring the damping fluid stays effective under various conditions.

What kind of springs do these shocks use?

These shocks come equipped with progressive rate springs. Progressive springs offer a more adaptable ride, starting softer and becoming firmer as they compress, which helps absorb smaller bumps while still handling larger impacts effectively.

Product Details

You're getting a pair of Progressive 412 Series shocks, measuring 13.0 inches long with a bright chrome finish. These shocks are built with a doublewall steel body and are gas charged to help ensure consistent damping performance. They're designed to be a solid improvement over stock suspension, offering a smoother, more controlled ride for your motorcycle.

What really sets these apart is the five-position cam-style preload adjuster.
