Explosive drive with controlled flex — carbon-reinforced TekFlex thruster fins built for speed, snap, and confidence at pace.
The 4.75” Advanced Thruster Fins are engineered for surfers chasing speed, precision, and controlled flex in a modern thruster setup. Built using carbon fiber reinforced TekFlex, these fins deliver a lively yet stable feel—loading up under pressure and springing back for explosive projection out of turns.
The performance hex composite core provides progressive flex through the tip, while the carbon fiber layers add torsional stiffness for drive and control at higher speeds. Finished in a distinctive carbon-on-green colourway, these fins balance performance aesthetics with functional design.
Designed for FCS II fin boxes, this tool-less thruster set locks in securely and is ideal for shortboards, step-ups, and performance hybrids in everyday to punchy conditions.
