FCS II H4 Quad Rear Set – The H4 looks and surfs different to any other fin. Precision Swiss engineering matched with a highly evolved template provides an unprecedented level of control and predictability at high speeds.

Quad Rears designed to work with both medium & large H4 sets. This set comes equipped with 2 x Quad Rear Fins, designed to work with both medium & large H4 sets.

While the science behind the template, materials & the foils are highly complex. Every component of this fin has been engineered to create a simple synergy between the fin & the surfboard, the rider & the wave.

Rear Fin Synergy: The H4 quad rear combines the power + control of the H4 thruster, with the added speed & drive of a quad.

Quad Rear Profile: A similar hybrid outline on the front and rear fins helps minimise turbulence + provides a smooth and predictable feel.

Enhanced Foils: Revolutionary new foil designed to grip longer through turns and promotes perfect rail to rail transitions.

Ideal Conditions
A wide range of conditions, particularly good in critical overhead waves.

Board Types
Designed to fit the FCS II Fin System.
