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

The 5-position cam-style preload adjuster lets you easily change how stiff the suspension is. You can adjust it to suit your weight, whether you're riding solo or with a passenger, or to match different road conditions.

Are these shocks filled with gas?

Yes, these shocks are high-pressure gas charged. This helps maintain consistent damping performance by preventing the oil from foaming, especially during hard riding or over rough surfaces.

What kind of springs do these shocks use?

These shocks come equipped with progressive rate springs. Progressive springs offer a softer initial feel that stiffens as they compress, providing a good balance of comfort and control for various riding situations.
