Frequently Asked Questions

What is Speed Adaptive Valving?

SAV automatically adjusts damping based on suspension movement speed, adapting to bumps and cornering forces for a smoother ride across varied terrain.

Can I adjust the ride height?

Yes — the shock is adjustable by ½ inch, allowing you to fine-tune ride height to your preference.

Are preload and compression adjustable?

Yes. Preload, high-speed compression, and low-speed compression are all user-adjustable to match your riding style and load.

Does the remote reservoir add complexity to installation?

The remote reservoir mounts are included. Installation requires mounting the reservoir away from the swing arm per the included instructions.

What makes the internal floating piston important?

The floating piston maintains consistent oil pressure, preventing fade during extended riding and delivering stable damping throughout the shock's range.
