Frequently Asked Questions

How do I adjust the preload?

The 5-position cam-style adjuster lets you dial preload up or down to match your weight and riding preference without tools.

Are these shocks rebuildable?

Progressive shocks are engineered for long service life. Contact Progressive directly about rebuild or warranty options.

What's the difference between standard and heavy-duty springs?

Heavy-duty springs support heavier riders or additional weight (luggage, passenger) without sagging. Standard springs work well for lighter riders.

Do these come with chrome covers?

The base shock comes bare. Show chrome covers are optional on select applications — check your bike's fitment before ordering.
