4.75" GM2 Thruster Fins – Carbon Fiber TekFlex
FCS II Compatible | 3-Fin Set
The 4.75" GM2 Thruster Fin Set is a high-performance three-fin configuration built from carbon fiber TekFlex construction for surfers seeking speed, drive, and responsive control. Designed to suit performance shortboards and modern hybrid shapes, this fin set delivers a balanced blend of projection and release across a wide range of conditions.
The AM2 template features a medium-rake outline that generates strong down-the-line speed while maintaining reliable hold through turns. Carbon fiber TekFlex construction adds stiffness where it matters, helping convert power directly into acceleration while still allowing controlled flex for smooth transitions and confident manoeuvres.
Fully FCS II compatible, these fins install tool-free in standard FCS II fin boxes and are supplied as a complete thruster set of three fins.

The wide base provides increased drive through turns, making them ideal for high performance surfing. The center fin is smaller than the side fins with a little more rake for increased maneuverability and control.
Designed for radical, progressive surfing, the raked side fins produce exceptional speed and drive, while the smaller center fin offers quick release through turns.
TekFlex fins have a carbon fiber over hex core construction making them lighter, with the strength and responsiveness of solid Pro Glass fiberglass fins.
They are perfect for powerful surfers or powerful waves.
TekFlex produces a robust, firm flex pattern without added weight. They are part of the next generation of fin manufacturing technology, engineered to be stiff and light.
These fins will give you a solid and engaged feel for those big drops, but be lightweight and responsive.
