8" International 4A Center Fin – Volan Pro Glass | Classic Longboard Fin for Sliding Center Fin Boxes.

Depth: 8” Base: 5.7”

The 8" International 4A Center Fin in Volan Pro Glass is a timeless longboard fin template known for its smooth drive, dependable hold, and flowing turns. With its moderate rake and balanced base, the 4A delivers clean trim speed while maintaining control through longer, drawn-out lines.

At 8", this fin provides excellent stability and projection without feeling overly upright or stiff, making it ideal for traditional longboards, performance logs, and midlengths ridden with flow rather than pivot-heavy surfing.

Constructed from premium Volan fibreglass, the fin offers a naturally dampened flex pattern that absorbs chatter and smooths out bumpy conditions. This classic layup is favoured by surfers who value glide, predictability, and a connected feel between board and wave.
