What makes these shocks an improvement over stock?

These shocks feature a doublewall steel body and nitrogen-charged valving for more consistent damping. The progressive rate springs and adjustable preload also allow you to fine-tune the ride for better comfort and handling compared to stock suspension.

How do I adjust the preload on these shocks?

The shocks have a five-position cam-style preload adjuster. You can rotate this cam to set the desired spring tension, which changes how the suspension responds to weight and bumps.

Are these shocks suitable for heavier riders or carrying cargo?

Yes, the five-position preload adjuster allows you to increase the spring tension to compensate for heavier riders or added cargo, helping to maintain proper ride height and suspension performance.
