The Turbo Thruster side fins are designed to be used in a tri-fin set-up with the 7.5" and 8.5" Turbo Tunnel fins only. (Using side fins with the 9.5" Turbo Tunnel Fin will create too much drag in the water.)

Each set comes with two side fins in red, blue, clear or yellow colors. At this time, the Turbo Thrusters are designed for Future Fin System and FCS Plug System fin boxes.

(The Turbo Thruster side fin can be used with any center fin.)
