Our Stealth 9" Hybrid Single Screw-in Fin kit brings the look and feel of a longboard surfboard to your soft top foam surfboard. Enjoy better turning capability, steeper drops, and an overall smooth ride typical of an old school longboard. We call it a "hybrid" because it combines a standard foamie screw-in fin base with a high-performance longboard shaped fin, giving your soft top board a unique look and enhanced performance. The fin edge is rounded for safety. Made of stiff ABS molded plastic, our custom fin design has only 2 pegs to screw in and not 3 like other brands, so there's no extra drilling required. Our conversion kit comes complete with screws and plugs to seal exposed fin holes and prevent water entry and drag. It's ideal for upgrading a beginner soft top surfboard to intermediate/advanced. The kit includes 1 ABS molded 9" soft top fin, 5 ABS fins screws, 4 1" fin hole plugs, and 1 2" leash plug screw. Screws and plugs install easily with a regular flathead screwdriver or even a coin!
