The 4.75" GM2 Thruster Fins in carbon fiber TekFlex are engineered for surfers who want maximum drive, fast response, and controlled release. Built on the trusted AM2 template, these fins provide a powerful base for committed turns while staying lively through transitions.

TekFlex construction blends carbon fiber with a tuned fiberglass matrix to deliver spring-loaded flex — loading through the turn and snapping back for acceleration out of it. The result is a fin that feels fast and precise without becoming overly stiff or tracky.

Compatible with Futures fin boxes, this thruster set locks in solidly and performs across a wide range of conditions, from punchy beach breaks to clean point waves.
