K4 ASYMMETRIC INCINERATOR US BOX

The Asymmetric Incinerator front fins! More power, more drive, more speed, less drag. These are something special!

Made from our ‘super stiff’ material the A.I’s are much like the rest of the Incinerator range – slim, high aspect and fast. Choose a size bigger than you would for the other fronts if you want the same hold.

The A.I. fin has a similar template to the Incinerator front but with a slightly wider chord. It has a 30/70 asymmetric foil optimised for quad set ups, but has also been found to work exceptionally well in thrusters.

Choose the degree depending on your boards box angles. Use the toe in calculator to find your boards box angle:
Note that quads require less toe in than a thruster to help alignment with the rears.

We now have the SB 10 and 11cm in half degrees! (Don’t sweat it though, the angle will give a blend of drive of drive and manoeuvrability. Changing the angle will only alter the blend and lean towards one or the other, it’s not a case of ‘working’ vs ‘not working’In my thruster I use the same angle as the Ezzy fronts ( 3º toe in ) to optimise riding. In onshore or ‘slower’ conditions you may prefer less angle.
