Product Details


These awesome fins use a unique patented design to give you:

  • Improved Directional Control
  • Greater Stability
  • Better Nose Rides
  • Smoother Turns
  • Increased Down the Line Speed
  • More Whitewater Control 

Made of Lexan for unmatched strength and durability. Includes a stainless steel Adjust-A-Bolt so you can easily make fin adjustments without tools. The Turbo Tunnel fits all standard fin boxes.  

How It Works

The water on the outside of the barrel travels faster than the water on the inside of the barrel. This allows the Turbo Tunnel Fin to travel through the water faster than other fins. Additionally, the tunnel design gives your board improved horizontal and vertical stability.

The 7.5" Turbo Tunnel fin works great on a wide variety of board designs and in all types of surf conditions. It gives your longboard improved turning, quick acceleration and great stability on the nose. It can be used as either a single fin or as a 2 + 1 set up on longboards and single fin retros from 7’ to 9’". With a 2+1 set-up position it slightly behind the side fins. As a single fin position it at the front of your fin box.


  • Length: 7.5”


  • 7’ to 9’ Surfboards
