FCS II H4 Quad Rear Fin Set

Introducing the FCS II H4 Quad Rear Fin Set, a game-changer in surfboard fins. This innovative set combines the precision of Swiss engineering with a highly evolved template to deliver unmatched control and predictability at high speeds. The H4 quad design is unique, offering a power and control that sets it apart from any other fin on the market.

Advanced Fin Design

The H4 Quad Rear Fin Set features a unique template and advanced materials. Each component is meticulously engineered to create a perfect synergy between the fin and your surfboard, as well as between you and the wave. Key benefits include:
  • Quad Rear Profile: Minimizes turbulence and provides a smooth, predictable feel.
  • Enhanced Foils: Grip longer through turns and promote perfect rail-to-rail transitions.
The H4 quad combines the power and control of the H4 thruster with the speed and drive of a quad, making it ideal for a wide range of conditions, particularly critical overhead waves.

Ideal for Performance Shortboards

Designed to fit the FCS II Fin System, the H4 Quad Rear Fin Set is perfect for performance shortboards with moderate-to-low rocker. This fin family is part of the Accelerator series, which focuses on control, speed, flow, and response. Key features of the new construction include:
  • Precision Swiss Engineered: Perfect synergy between fin geometry and HI-FI materials for a smooth and predictable feel.
  • High Density Uni-Directional Carbon Fibre: Light and super strong, transferring more of your energy into speed.
The dynamic trailing edge enables the fins to be pushed harder without sliding out, making them ideal for aggressive surfers seeking maximum performance. Experience the difference with the FCS II H4 Quad Rear Fin Set.
