Why Choose Our Quad Rear Fins

If you've already got a 5-fin board, quad rears let you switch between thruster and quad without buying two complete sets. Pull out the centre fin, slot in the rears behind your existing fronts and you've got a completely different board under your feet.

Rear fins are smaller by design and angled to channel water toward the tail for speed and projection. 

Larger rears give more hold and drive. Smaller rears give a looser, faster feeling. Just make sure the system matches your fronts, FCS II with FCS II, Futures with Futures. Our team can help pair them up if you're unsure.
