What makes these shocks an improvement over stock?

These shocks feature a doublewall steel body and nitrogen-charged, multi-stage valving. This design helps provide smoother, more consistent damping compared to many stock suspension units.

How do I adjust the preload on these shocks?

The shocks are equipped with a five-position cam-style preload adjuster. You can rotate this adjuster to set the spring tension for your specific riding needs and load.

Are these shocks suitable for heavier riders or carrying cargo?

Yes, the five-position preload adjuster allows you to increase spring tension, which is beneficial for heavier riders or when carrying extra weight like saddlebags or a passenger.
