Product Information

Full details

The Deflow Deadkooks Impulse Longboard Fin is designed for longboarders riding boards 9'0 and above who prioritize a balance between nose-riding stability and maneuverability. A collaboration between shaper Eden Saul and Deflow, this 10-inch fin offers reliable hold and increased drive, though its stiff flex profile may feel less forgiving than more flexible, pivot-style fins for casual cruisers.

FAQs

What size boards is this fin designed for?

The Impulse fin is specifically designed for longboards 9'0 and above.

Is this fin made of fiberglass?

Yes, it is part of the Deflow Pro Tech Collection, featuring high-quality, stiff construction.

How does this fin affect nose-riding?

The ample 185mm base provides the stability needed to hold the tail in the water while you are out on the nose.

Does this fin come with a screw and plate?

Yes, it includes the necessary hardware for standard longboard box installation.

Will this fin fit in a Futures or FCS side-bite box?

No, this is a single fin designed for a standard US longboard center fin box.

How do I determine the best placement in the box?

Place it further back for increased tracking and stability, or move it forward to make the board pivot more easily.

Troubleshooting

Fin feels loose in the fin box

Ensure the brass plate is tightened securely and consider using a thin piece of plastic shim if the fin base is undersized for your specific box.

Difficulty inserting the fin

Check the fin box for sand or debris. Clean thoroughly with fresh water and ensure the screw is fully retracted before sliding the fin into place.

Pros and Cons

Pros

  • Excellent hold during nose-riding maneuvers
  • Provides significant drive through turns
  • Robust stiff construction prevents flex-related speed loss
  • Tailored specifically for longboards 9'0 and above
  • High-quality Pro Tech Collection craftsmanship

Cons

  • Stiff profile requires a more active surfing style
  • Less suited for boards under 9'0
  • Lack of flex may feel too rigid for some traditional logs

Setup, Compatibility & Care

This fin is compatible with standard US longboard fin boxes. To install, slide the brass plate into the box, position the fin base, and secure it using the provided fin screw and plate. Ensure the fin is pushed all the way back in the box for maximum tracking, or move it forward for a looser feel. After every session, rinse the fin box and the fin thoroughly with fresh water to prevent salt crystallization. Periodically check the fin screw tightness, as vibration can cause it to loosen over time.
