Lib Tech Fin Set

No, these fins are exclusively compatible with the Lib Tech LIB FOCII fin system. They will not fit into standard FCS or Futures boxes.

A five-fin set gives you the flexibility to switch between a thruster (tri) setup for more control and pivot, or a quad setup for increased speed and drive. It effectively allows you to tune your board to the specific wave conditions you are surfing that day.

This set is designed for surfers who want versatility. If you frequently travel or surf a variety of breaks—from punchy beach breaks to long, open-faced waves—the ability to toggle between tri and quad configurations makes this a highly practical choice.

No, the set comes with the proprietary fin key required for installation. You have everything you need to swap your fins right out of the box.

The quad configuration generally provides more speed and hold through turns, making it excellent for down-the-line surfing or barrels. The thruster setup offers a more predictable, vertical approach that is often preferred for tighter maneuvers in the pocket.
