FCS II Split Keel Quad Fin Set (Used)

Experience the perfect blend of twin-fin speed and quad-fin control with this used FCS II Split Keel Quad Fin Set. Designed for fish surfboards, hybrids, and modern performance shapes, the Split Keel Quad combines the fast, flowing feel of a traditional keel fin with the added hold, drive, and responsiveness of a quad-fin setup.

The split-keel design creates exceptional down-the-line speed while maintaining smooth rail-to-rail transitions and powerful projection through turns. Compared to a traditional full keel, the split-keel configuration offers increased maneuverability and a looser, more responsive feel without sacrificing the speed-generating characteristics that make keel fins so popular. The rear quad fins add control and stability, allowing surfers to push harder through turns and maintain hold in steeper sections.

Compatible with the FCS II tool-free fin system, this quad-fin setup is ideal for surfers looking to maximize speed in smaller waves while retaining enough control for larger, more powerful surf. Whether you're riding a fish, hybrid, groveler, or performance quad, the Split Keel Quad delivers a unique balance of glide, drive, and modern performance.

This fin set is in used condition with normal cosmetic wear from regular use but remains fully functional and ready for the water.
