What is the main benefit of the progressive rate springs?

Progressive rate springs offer a more comfortable ride by starting softer and getting stiffer as they compress. This helps absorb smaller bumps while providing better support during harder braking or when carrying a passenger.

How do I adjust the preload on these shocks?

These shocks feature a five-position cam-style preload adjuster. You can rotate the cam with a suitable tool to change the spring tension, allowing you to fine-tune the ride height and stiffness based on your load.

Are these shocks suitable for heavy loads or two-up riding?

Yes, the five-position preload adjuster allows you to increase the spring tension for heavier loads or two-up riding, providing the necessary support and maintaining proper ride height.
