✔ Strong drive from large front fins
✔ Rear stabilisers improve control
✔ Durable solid fiberglass construction

Description

The Eveley DTR Quad Fin Set (4.9" / 3.1") is engineered for surfers who want the speed advantage of a quad setup with dependable rail hold and turning control.

The 4.9" front fins generate powerful drive, helping surfers accelerate quickly and maintain momentum through fast sections.

The 3.1" rear fins stabilise the tail, keeping the board controlled during turns while still allowing quick release when transitioning between rails.

This configuration reduces drag compared with thrusters, allowing the board to generate more natural speed from the wave.

Constructed from solid Pro Glass fiberglass, these fins provide:

• consistent flex
• strong durability
• precise response under load

Quad setups are particularly effective in fast beach breaks, point waves and hollow surf, where speed generation is critical.
