Frequently Asked Questions

What is Speed Adaptive Valving (SAV)?

SAV is a damping system that adjusts shock response in real time based on road conditions, delivering smoother rides on both smooth highways and rough roads without manual adjustment.

Do I need special tools to adjust the preload?

No. The spring preload cap is designed for easy hand adjustment without any special tools.

Will these fit my 1995+ FXR?

No — this part is for 1982–1994 FXR models only. Later FXR years use different shock geometry.

Can I use these on a 2021+ Sportster?

No — fitment ends at 2020 model year. Check with HardDrive for 2021-newer Sportster-specific shocks.
