FRP Side Bite & Rear Trailer Surfboard Fins – 2-Piece Set with Hardware

Overview

More drive. More control. More ways to fine-tune your surfboard.

Customize your surfboard setup with the FRP Side Bite / Rear Trailer Fin Set. Designed to provide additional setup options, these two fins can be used as side bites alongside a compatible single-fin configuration or as rear trailer fins when adapting a compatible thruster board to a quad arrangement.

Constructed from fiberglass-reinforced polymer (FRP), these fins offer a durable alternative to standard nylon fin construction. The added fins are intended to help riders fine-tune drive, stability, and control according to their board design and preferred surfing style.

The set includes two fins, fin screws, and a fin key, providing convenient accessories for installation on compatible fin boxes.

Key Features & Benefits

• Versatile Fin Configuration: Designed for use as side bites or rear trailer fins on compatible surfboards.

• Two-Fin Set: Includes a pair of fins for the intended configuration.

• Fiberglass-Reinforced Polymer (FRP): Combines polymer material with fiberglass reinforcement for a durable fin construction.

• Additional Drive and Control: Intended to help tune board handling when used in a compatible multi-fin setup.

• Single-Fin Setup Option: Can be used as side bites alongside a compatible center-fin setup.

• Quad Conversion Option: May be used as rear trailer fins to convert a compatible thruster board to a quad configuration.

• Fin Screws Included: Provides mounting hardware for compatible fin boxes.

• Fin Key Included: Makes installation and removal more convenient.

Fine-Tune Your Single-Fin Setup

Adding side bites to a compatible single-fin board creates a 2+1 configuration. This arrangement can provide additional lateral support and change how the board responds through turns compared with a single-fin setup alone.

Explore a Quad Configuration

These fins can also serve as rear trailer fins for a compatible board with the correct fin-box layout. A quad setup uses four fins and is often chosen by surfers seeking speed and drive, although actual performance depends on the board, fin positioning, and wave conditions.

Fiberglass-Reinforced Polymer Construction

FRP combines a polymer base material with fiberglass reinforcement. The supplier describes this material as stronger than standard nylon fin material; actual strength and durability depend on the specific construction and testing.

Convenient Installation Accessories

The included screws and fin key help simplify setup, making it easier to install or remove the fins when changing a compatible configuration.

Compatibility & Installation

Before ordering, verify that your surfboard has the correct fin-box arrangement for the intended setup. Adding side bites to a single-fin board requires compatible side-fin boxes, while converting a thruster to a quad requires appropriate rear fin boxes and a suitable fin layout.

Fin bases are not universally interchangeable. Confirm the base type, dimensions, and mounting requirements with the supplier before purchase. Use the included screws and fin key according to the surfboard manufacturer's instructions, and make sure each fin is securely installed before entering the water.
