FCS II Surfboard Fin Boxes 

Side Fins are sold as sets of two (1 left, 1 right)

Available in the following Colors:

White - Black - Charcoal Gray - Red - Reef Blue - Acid Yellow

The FCS II surfboard fin system is the strongest and highest performing finbox on the market to day. Simple pre-glass finbox installation makes a tight foam-to-foam connection for optimal torsion strength that just might be the difference between continuing your session after a collision with something or having to replace your finbox.

When paired with fins from the new FCS II Essential Series Fins, it’s now possible to install and remove your fins in seconds, without the need for any screws or tools. an aerospace grade titanium spring loaded rod locks the fin base into the fin box which improves surfing performance by transferring energy from the surfer's pressure on the board straight to the fin without any delay from a looser finbox to fin connection, like a glass-on fin. 

Requires the FCS II router jig and pattern bit for installation


Available in the following cant degrees:

0 degree (center fin)
3 Degree (typically used as quad rears for more drive)
5 Degree (typically used as quad rears, or create more drive as front fin cant)
9 Degree (typically used as front fins for looser turns and control)

QUESTIONS & ANSWERS

Ask a Question
  • I believe for the tri fin setup I order #2 canted fins and they come automatically 1 left and 1 right and order #1 0 canted fin for the center fin? Correct?

    Yes that is correct. The FCS II fin boxes come in a set of left and right side fins, the center fin box has no cant built in (0 degree cant)

  • Which quantity and degree should I purchase for a standard thruster shortboard

    The degree of cant in the fin box depends on how you want the board to perform.

    Choose 5 degree fin cant for faster, down the line surfing. Choose 9 degree fin cant for more turning ability as the fin pivots quicker at a higher degree.

    You'll need a 0 degree centerfin box too of course for the tri fin set.

    For quad fins choose 9 degree for the front fins and 5 degree or 3 degree for the rear fins depending on your speed vs. turning preference.
