What is the main benefit of the progressive rate springs?

Progressive rate springs offer a more adaptable ride. They start softer for comfort over smaller bumps and stiffen up as they compress, providing better support during hard braking or when carrying heavier loads.

How do I adjust the preload on these shocks?

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

Are these shocks suitable for heavy riders or carrying a passenger?

Yes, the 412 Series shocks are available in Standard or Heavy-Duty options for select applications, and the adjustable preload allows you to compensate for heavier loads or a passenger, improving ride quality and handling.
