Turbo Thruster fins are 6cm side fins made to compliment the Turbo Tunel fins when used in a Thruster set up. These fins look great, are very durable and are made from GE Lexan Plastic (TM). Turbo Thruster fins add a great dimension to the performance of the Turbo Tunnel fins and fit any FCS or Futures plugs. Throw them on your board today and enjoy. We love them and are pretty confident that you will too! At just $25 they make an excellent Christmas gift for someone you know who loves nothing better than putting the "toe on the nose"!
