Frequently Asked Questions

Can I adjust these shocks myself?

Yes — preload adjusts by hand threading, and rebound damping has a user-accessible knob to fine-tune ride quality without tools.

Will these fit my 2006+ Dyna?

No — this part number is engineered for 1991-2005 Dyna chassis. 2006 and newer Dynas require a different shock.

What's the difference between 494 Sport and other Progressive models?

The 494 Sport is designed for riders seeking adjustability and performance at a lower price point, with proven monotube and damping technology.

Do I need new mounting hardware?

These shocks use standard Dyna mounts — your existing hardware will work. Check condition and replace if worn.
