FCS II Al Merrick Quad Rear Fin

Yes, these are designed specifically for the FCS II fin system. They feature a tool-less installation process that allows you to click them in and out without needing a key.

These are specifically engineered as rear fins for a quad setup. They pair best with raked side fins to balance out the board's drive and hold, particularly on performance-oriented shortboards.

The flat foil promotes a smoother, more consistent arc through your turns. It provides the stability you need for barrel riding while remaining responsive enough for radical, progressive maneuvers.

Performance Core construction uses a multi-layered resin transfer molding process to create a progressive flex pattern. This means the fins feel lively and responsive, offering a reliable balance between drive and hold when you are pushing hard through a turn.

While they are built for performance, they excel in hollow or punchy conditions where you need extra control. If you are surfing smaller, softer waves, you might find a different fin template provides more speed, but these are excellent for when the surf gets critical.
