They are considered a large set of thruster fins.
The 4.75" DSP Thruster Fins are designed for surfers who surf with speed, power, and commitment. Featuring a large, drive-oriented template with a solid base and refined tip, these fins deliver strong projection through turns while maintaining control at high speeds.
Constructed from carbon fiber TekFlex, this fin set offers a lightweight yet highly responsive feel. The carbon base increases stiffness and energy transfer for explosive acceleration, while the TekFlex layup provides controlled flex through the tip for smooth release and stability under load.
Fully Futures compatible, these fins install securely using the single-tab Futures system, delivering a solid, connected feel preferred by surfers who push hard through powerful maneuvers.

FAQ’s
What type of surfer are the 4.75" DSP Thruster Fins best for?
These fins are best suited to intermediate to advanced surfers who generate their own speed and surf with power. The MF-style template is designed for strong drive, stability, and control during committed, high-speed turns.
How does carbon fiber TekFlex affect performance?
Carbon fiber TekFlex delivers a stiff, responsive base with controlled tip flex, improving acceleration, energy return, and snap. Compared to standard RTM hex fins, TekFlex feels faster and more precise, especially at higher speeds.
Are these fins compatible with my surfboard?
Yes. These fins are Futures compatible and fit surfboards with Futures fin boxes. They use the single-tab Futures system for a secure, locked-in feel.
What wave conditions do these fins perform best in?
The 4.75" DSP Thruster Fins perform best in waist-high to overhead waves, particularly in punchy beach breaks and reefs where drive and control through turns are critical.
How many fins are included in the set?
This product includes a set of three fins, providing a complete thruster fin setup.
Are these fins suitable for lighter or less powerful surfers?
Lighter or less aggressive surfers can still use these fins, but they may prefer a smaller or more flexible RTM hex core fin if they want a looser, more forgiving feel at lower speeds.
