Frequently Asked Questions

Are these shocks easy to adjust?

Yes — preload adjusts by hand thread and rebound tuning is tool-free, allowing you to dial in the ride without a shop visit.

Will these fit my Dyna with aftermarket wheels or a lowering kit?

These shocks are engineered for stock Dyna geometry. Verify ride height and clearance if running significant modifications.

What's the difference between standard and bearing bushings?

Bearing bushings reduce friction for a smoother ride; standard bushings are slightly stiffer. Both are included.

Do these require installation by a professional?

Shock installation typically requires spring compression tools and suspension knowledge. Many riders use a shop, though experienced DIYers can handle it.

How do I get the best performance from these shocks?

Start with factory preload settings, then adjust based on load and riding style. Experiment with rebound damping to dial out harshness without sacrificing control.
