FCS II JS PC Fin Set

Performance Core material is designed to mimic the feel of traditional fiberglass fins but with a significant reduction in weight. It offers a consistent, reliable flex pattern that helps you maintain speed through turns while remaining responsive.

These fins are specifically engineered for performance-oriented surfboards that feature deep concaves and moderate-to-extreme rocker. While they will fit any FCS II box, they will perform best on boards designed for high-speed, down-the-line surfing rather than grovelers or flat-rocker fish shapes.

A five-fin set gives you the versatility to adapt to changing surf conditions. You can run them as a thruster for a more pivot-oriented, snappy feel in punchy waves, or switch to a quad setup when you need more speed and hold on open-face, down-the-line waves.

These fins excel in open-face, down-the-line conditions, making them a standout choice for point and reef breaks. Their design prioritizes speed and flow, which are essential for navigating longer, cleaner waves.

Designed by Jason Stevenson, this template is tuned for powerful, drawn-out turns. It provides more drive and hold than a neutral, all-around fin, allowing you to push harder through your maneuvers without the fins feeling loose or skittish.
