Compatible with all Gremlin board models/versions, FCS II twin fins provide the perfect balance of drive on rail and the 2" nub "cheater fin" down the center line eliminates play while riding flat. FCS II fins install without the use of a tool, while the center nub fin is fixed with the supplied FCS tool.
