Surfboard 5th Stabilizer Fin

Throw a 5th Stabilizer Fin into your quad setup, if you're looking for just a bit more control and smoothness.

We've even had some customers use two stabilizer fins as the rear trailers in their quad setup (instead of using just one as a fifth center fin).

Play around with it and have some fun!

Fin key and screws are included.

Stabilizer Fin Material

Lightweight honeycomb fiberglass construction matches perfectly with our quad honeycomb fins.

FCS Stabilizer Fin Installation

Unscrew your fins screws enough so you can insert the stabilizer fin. You do not need to completely unscrew the fin screws.



Insert the stabilizer fin. (Our FCS fins work with the original FCS plugs, and also with FCS II plugs).



Gently tighten the screws until snug (do not overtighten and strip your fin plugs!)

Unscrew your fin screw enough so you can insert the fin. You do not need to completely unscrew the fin screw.



Insert the stabilizer fin. Hook the rear of the fin into the box first, then push the front end down.
