Frequently Asked Questions

FST allows the shock to sense bump frequency and automatically adjust oil flow through internal ports, matching damping to road conditions for a smoother ride on both small and large impacts.
Do I need special tools to adjust the preload?
No — the top-mount threaded preload adjuster allows you to fine-tune spring pressure by hand with a simple twist.
Can I choose between spring rates?
Yes — the 444 Series comes in both standard and heavy-duty spring rate options to match your riding style and load.
What finish options are available?
Choose black or chrome finish depending on your bike's aesthetic.
