Bell GT6 RD ULTRA-4C/EC FIA 8859-2024/Snell SA2025 Carbon Helmet

FIA 8859-2024 / SA 2025

The Bell GT6 RD Carbon-4C/EC delivers pro-grade safety and communication in a lightweight, closed-cockpit package. Drawing design inspiration from the aggressive HP6 platform, it features a wide eyeport for integrated visibility, a premium carbon composite shell, and all-in communications and hydration solutions built in.

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 4-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). Carbon-4C/EC” in model name means the helmet is a Carbon Composite 4-layer shell with EC (electronic comms) kit integration.

Ultra-Light Carbon Construction Meets Pro Racing Preparedness

Built with superior carbon-glass composite materials, the helmet keeps fatigue low and track awareness high. Integrated ZeroNoise® electronics, high-power speakers, and a noise-canceling mic ensure outstanding comms and sound insulation. The face piece is also optimized for ventilation and hydration—perfect for endurance and closed-cockpit racers.
