An unprecedented amount of innovation is currently occurring with fins and fin systems. Ranging from the simple to complex, tool-less fin attachment, to a wide range of other options.

Our choice was to go back to basics, with a system that is light, strong, while at the same time simple to install and easy to use. A design optimized for under the glass installation. The goal was to deliver a system that was both simple and familiar for builders to install, and surfers to use.

GEARBOX is an innovative new fin system. It is strong, light, easy to install, dual tab compatible, and customizable.

A unique patented LOAD BEAM COLLAR offers customization options through the installed cover! System has an inexpensive routing system that simplifies and expedites the installation process.
