FCS II Reactor PC Thruster Fins

These fins are designed for surfers who prioritize speed and tight, aggressive turns. The upright template makes them ideal for quick, acute directional changes rather than long, drawn-out carves.

The smaller center fin is specifically engineered to increase pivot and allow for easier tail release. This helps you break the tail loose during turns, which is particularly useful in hollow waves and punchy beach breaks.

These are FCS II fins, which are designed for the FCS II fin system. They are compatible with most modern performance shortboards that use this system, allowing for tool-free installation.

The Reactor PC Thruster fins are recommended for riders up to 175 lbs. If you exceed this weight, you may find the fins feel too loose or lack the necessary drive, and you might want to consider a larger fin size.

Performance Core construction is designed to provide a responsive, lively feel. It offers a balance between stiffness and flex, giving you the control needed for high-performance maneuvers without feeling overly rigid.

While they can work in various conditions, they are optimized for hollow waves and beach breaks where quick, tight turns are required. For long, open-face waves where you want to draw out your turns, you might prefer a fin with a more raked template.
