What makes the Progressive 412 Series 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 for a more customized and comfortable ride compared to many stock setups.

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 cam to set the desired spring tension, which changes how the suspension reacts to weight and bumps.

Are these shocks sold individually or as a pair?

These shocks are typically sold as a pair to ensure balanced suspension performance on your motorcycle. Please check the product listing details to confirm the quantity included.
