Frequently Asked Questions

Can I adjust the preload myself?

Yes — Progressive designed hand-threaded preload adjustment so you can dial it without tools as your bike's load or riding style changes.

Are these rebuildable?

Yes. Progressive backs these with a lifetime limited warranty and offers rebuild and re-valving services through authorized shops.

Will these fit my 2018+ Dyna?

No — this part is for 2006-2017 Dyna models. Newer Dyna frames require updated shock geometry.

Do I need to adjust anything after installation?

Set preload to match your typical riding weight, then fine-tune rebound damping with a few test rides. Start at the middle detent and adjust up or down based on how the bike feels.
