Frequently Asked Questions
Do I need to adjust these shocks after installation?
Yes — set preload by hand to match your weight and riding style, then fine-tune rebound damping with the adjustment knob. Progressive provides tuning guidelines with each shock.
Will these fit my 2006+ Dyna?
No — this part number is specific to 1991-2005 Dyna 494. Newer Dyna models require different shocks.
Can I ride right away after installation?
Yes, but ride gently until you've set preload and rebound to suit your weight. Progressive recommends bedding in new shocks over the first 50 miles.
What's the difference between these and Progressive's higher-end shocks?
The 494 Sport uses proven monotube and damping tech without electronic adjustments, keeping cost down while maintaining responsive handling.
