Frequently Asked Questions

Can I adjust the ride on these shocks?

Yes — hand-threaded preload and rebound damping both adjust so you can dial in stiffness and rebound speed to match your weight and riding style.

Will these fit my 2006+ Dyna?

No — this part number is specific to 1991-2005 Dyna models. 2006 and newer require a different shock.

What happens if the shock bottoms out hard?

The engineered jounce bumper with built-in metal cup absorbs and smooths out hard bottoming impacts to protect the frame and improve comfort.

How does the progressive spring work?

The spring rate increases as it compresses, giving a soft initial ride over small bumps while maintaining support under hard braking or cornering.

Does this come with a warranty?

Yes — Progressive includes a lifetime limited warranty on these shocks.
