Shop quad surfboard fins and quad rear fin sets for boards designed to be ridden with four fins. Quad setups can generate plenty of speed and drive while maintaining good hold through turns, making them popular on everything from fishes to performance shortboards.

Choose complete quad sets or replacement quad rear fins for FCS II, Futures and compatible fin systems. If you're converting a five-fin board from thruster to quad, make sure the front and rear fins are correctly matched.
