What is included with these shocks?

This product includes a pair of 11.0-inch Progressive 412 Series shocks in a chrome finish. The necessary hardware for installation is typically included, but it's always best to refer to the manufacturer's instructions for a complete list.

How do I adjust the preload on these shocks?

These shocks feature a 5-position cam-style preload adjuster. You can rotate the cam mechanism to select your desired preload setting, which changes the stiffness of the suspension to match your riding needs.

What is the difference between standard and heavy-duty springs?

While this specific model comes with standard progressive rate springs, Progressive offers heavy-duty options for select applications. Heavy-duty springs are typically designed for heavier riders or for carrying extra weight, providing a firmer suspension setup.
