Integrated ZeroNoise Communications With High-Power Speakers

The GT6 PRO RD-4C/EC features Bell Racing's integrated ZeroNoise communication system, designed to deliver clear communication between the driver and pit crew during competitive racing.

Unlike the standard GT6 PRO RD-4C configuration, which incorporates an input for compatible in-ear monitors, the RD-4C/EC includes integrated high-power helmet speakers and a noise-canceling microphone.

This setup is especially beneficial for drivers who prefer an integrated speaker system rather than separate racing earbuds.

The ZeroNoise electronics help improve communication clarity in noisy racing environments, allowing drivers to receive important instructions, respond to crew members, and maintain concentration during high-speed competition.

A compatible external racing radio and communication connections are required for complete system operation.

Lightweight Carbon-Fiberglass Composite Shell

Derived from Bell Racing's HP6 design, the GT6 PRO RD-4C/EC features a premium carbon-fiberglass composite shell developed for professional motorsport applications.

The lightweight composite construction works with an advanced multi-density, multi-piece interior liner to manage impact energy while maintaining driver comfort.

The helmet's aerodynamic profile is optimized for enclosed race vehicles, making it suitable for sports car racing, touring cars, GT competition, and endurance racing.

Its gloss Titanium finish gives the GT6 PRO RD-4C/EC a distinctive appearance while maintaining Bell Racing's proven shell construction and safety technology.

Wide SE06 Eyeport and Bell SmartLock Shield System

Excellent visibility is essential for safe racing, particularly when navigating traffic, monitoring mirrors, and approaching corners at high speeds.

The Bell GT6 PRO RD-4C/EC features a wide eyeport designed to maximize forward and peripheral vision in closed-cockpit vehicles.

The included clear shield uses Bell's SE06 shield design, while the integrated SmartLock mechanism provides secure shield retention.

Additional compatible Bell SE06 shield options may be available separately for different lighting and racing conditions.

Ventilation and Forced-Air Cooling Compatibility

The GT6 PRO RD-4C/EC incorporates strategically positioned extraction vents to improve air circulation and help remove warm air from the helmet during demanding racing sessions.

For drivers competing in hot conditions or extended endurance events, the helmet accepts compatible optional top and side air intake systems that connect to external forced-air cooling equipment.

Integrated channels within the facepiece provide additional routing options for compatible hydration tubes, drinking valves, and communication accessories.

These features make the helmet a versatile choice for drivers building a complete racing safety and communication system.

Factory-Installed HANS Anchors

The Bell GT6 PRO RD-4C/EC comes equipped with factory-installed HANS anchors as original equipment.

These anchors allow the helmet to connect to compatible head and neck restraint systems without requiring separate anchor installation.

Always verify proper fitment and compatibility with your specific head and neck restraint system.
