Arai TD-2 Rear Duct

The Arai TD-2 Rear Duct is a genuine factory replacement ventilation component engineered specifically for premium Arai full-face motorsport helmets. Positioned at the back of the shell, the TD-2 duct acts as a critical exhaust pathway. It utilises low-pressure venturi forces to draw hot, stagnant air and humidity out from the helmet interior while stabilising high-speed airflow detachment behind the driver's head. Replacing a lost or track-damaged rear duct is essential for maintaining optimum driver cooling and minimizing helmet lift down fast straights.

Seamless Transparency & Aerodynamic Balance

Moulded from a premium, high-grade clear polymer, this replacement TD-2 duct is designed to integrate flawlessly into any helmet configuration. Whether your shell features the standard factory paint finish or a highly intricate, multi-layered custom livery layout, the transparent material allows your underlying design lines and graphics to show through perfectly without visual interruption.
