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

The five-position cam-style preload adjuster lets you easily fine-tune the suspension's stiffness. This allows you to set the ride height and damping characteristics to match your weight, riding style, or if you're carrying a passenger or cargo.

Are these shocks filled with nitrogen or just air?

These shocks are high-pressure gas charged, which typically means they are filled with nitrogen. This helps to prevent oil and gas from mixing, ensuring consistent damping performance and preventing fade, especially under demanding conditions.

What kind of springs come with these shocks?

These shocks come with progressive rate springs. Progressive springs offer a softer initial feel that stiffens as they compress, providing a good balance of comfort for everyday riding and support when you need it.
