Frequently Asked Questions

Will these fit my Softail Heritage Classic?

No — these shocks are not tuned for Heritage Classic models. Contact FOX to confirm compatibility with your specific Softail variant.

Can I adjust the rebound without tools?

Yes. The QS3 system gives you 3-position rebound settings without removing the shock or using special tools.

Can I adjust preload without special equipment?

Yes. Preload adjustment uses FOX's guide marks on the preload ring — no tools required for basic tuning.

Are these shocks rebuildable?

Yes. These shocks are fully rebuildable and re-valvable, allowing for service and custom tuning by FOX or authorized rebuilders.

What's the difference between IFP and standard shocks?

IFP (Internal Floating Piston) gas-charged design maintains consistent damping across temperature ranges and ride conditions better than conventional sealed shocks.
