  • Overview

    • Specialty split keel quad fin set.
    • High area quad keel set adds bite and control to hybrid boards with wide tails, without sacrificing pivoting capabilities.

    Board Types

    • Designed to fit the FCS II Fin System.
    • Recommended for all board types including modern fish and hybrid models with moderate-to-low rocker.
  • Performance Glass

    Performance Glass (PG) fins are machine cut from layers of solid fiberglass. These fins are stiff, and are widely used by pro level surfers because the integrity of the flex is maintained under immense force, and in the most extreme of conditions and situations.

  • Large - Extra Large (One size suits all)

    You may notice new size ratings for our Specialty Fin Range. Previously, all Specialty Series fins were rated an XL. To better reflect fin sizing, we now have 3 new size categories:S-M, M-L, and L-XL.

    Super fun

    I put them in a lost puddle jumper, gives the board ton of drive, full lay rail turns yet still allows the tail to release when you want it. Gave me more confidence to surf the board a bit harder. I think it’s a perfect blend of a fish type feel with a little more aggressive abilities! Went better on a slower reef break feels a little too on rails for a beach break though!

    Grippy carvers

    Plenty of grip on the take off drop bottom turns with this design whilst not comprising speed when you're hot-dogging to make a section and it also gives you some sweet power when slices up fat faces

    Quad split keel fins

    Unique design, yields increased performance...long time thruster fan but these fins really made my FireWire/EVO come alive, speed, quickness and solid feel during hard turns. I even tried them on my new FireWire/Seaside. I really liked the way they felt and especially the way they looked on the board. I really love this fin set up, looks , performance and high quality construction. Why buy a new board when changing your fin set up can make such a hugh difference in feel and the way the board works? I have two boards and 4 sets of FCSll fins and I feel that I have a quiver of five boards because of the versatility these well designed fins provide. I even think they have made a difference in the level of performance of my surfing. I am stoked! Thanks!
