Bell GT6 RD Carbon-4C Helmet

This is a pre-order, shipping after Q3 2025.

The Bell GT6 RD Carbon-4C is a closed-cockpit performance helmet built for drivers who want ultra-light carbon construction with integrated communications and hydration capability out of the box. A wide eye port, refined aerodynamics, and efficient ventilation keep vision clear and fatigue low through long stints.

4C: Carbon Composite 4 Layer Construction

On Bell helmets, “4C” stands for “Carbon Composite 4 Layer Construction.” It refers to the shell technology Bell uses: a four-layer carbon composite laminate. This blend typically combines carbon fiber with other advanced fibers (like Kevlar or fiberglass) in multiple layers.

The purpose is to deliver a shell that is lighter than fiberglass alone, but more affordable and versatile than Bell’s top-end full carbon HP series shells (like HP7 or HP77, which use pure carbon/advanced aerospace layups). In this helmet, "RD-4C” means the helmet is a Carbon Composite 4-layer shell with RD (radio/drink) kit integration.

Designed for GT and Closed-Cockpit Racing

The RD configuration includes electronic ear cups and drink-tube routing for clean, reliable comms and hydration in noisy, high-heat cabins. Internal channels manage airflow across the crown and face, and the shell profile is tuned for stability with optional aero accessories.
