Three of our safety fins with the screws designed to fit Rock-It Surf Chub (4'10"), Softy (8'), and Moby (9') boards. Rubber washers also included to help keep water from seeping into the board. This fins are universal with most other screw-through soft top surfboard brands. We have three different sizes--the fins are all 4.5", however the screw length is different between the three sizes to accommodate for thicker boards as the boards are larger. Rock-It Surf screw through fins are more rigid than many competing fin sets, allowing for higher performance and harder/more accurate turns since there is less flex in the fin. All fins are 50/50 foiled. These black fins are made of ABS plastic and are durable and come with Rock-It Surf's one year warranty against any manufacturing defects.

  • Choose your Board Size for Best Match: The fins are all 4.5" each, however, the fin screw lengths differ by 5mm/each depending on the size of board. That's why we offer fin sets for softboards 6ft and under; 7ft & 8ft, and 9ft sizes. Purchasing the right screw length will keep you from having to trim excess screw length plastic to provide a flush fit on your surfboard.
  • Universal: Rock-It Surf soft surfboard fin replacement sets are universal and fit most every other brand of soft surfboard utilizing screw-through fin sets.
  • 3 fin Thruster Design: 3pcs 4.5" fins with rubber washers (to prevent water seepage) and 6 screws + washers are included in your kit. Thruster fin setups provide stability and drive, suiting most surfing conditions the best.
  • Simple Installation: Simply place the fins into the underside of the board and use the convenient screws to secure to the top deck with a large screwdriver or coin.
  • Performance: Rock-It Surf screw through fins are more rigid than many competing fin sets, allowing for higher performance and harder/more accurate turns since there is less flex in the fin. All fins are 50/50 foiled
  • Rubber washers included: Unlike generic replacement fin sets on the market, this set from Rock-It Surf includes rubber washers on both the fins and the screws to prevent water seepage into your board and extend it's lifespan.
