Common questions
What is the primary benefit of the QS3-R piggyback design?
The QS3-R piggyback design on these FOX shocks for your Harley Dyna provides separate reservoirs for the gas and oil, which helps to maintain consistent damping performance by preventing aeration and allowing for more precise adjustments to both compression and rebound.
Will these 13.5" shocks affect the stance of my Dyna?
If your current shocks are shorter than 13.5 inches, installing these will raise the rear of your Dyna, which can improve ground clearance and lean angle. Always check your current shock length to understand the impact on your bike's stance.
Are these shocks suitable for aggressive riding on my Dyna?
Yes, with their fully adjustable 3-position damping and robust construction, these FOX IFP-QSR shocks are ideal for aggressive riding, providing enhanced stability and control through corners and over various road surfaces on your Harley Dyna.
