Arai GP-5K Top Duct

The Arai GP-5K Top Duct is a genuine factory replacement ventilation component engineered to maintain optimum cooling and aerodynamic performance. Over consecutive track sessions, top ducts can become clogged with racetrack grime, damaged by flying gravel, or cracked during routine transit in your gear bag. This official Arai part allows you to easily restore your helmet's original ventilation profile without altering the structural integrity of the shell.

Versatile Fitment & Clean Styling

Moulded from a premium, high-grade clear polymer, this replacement duct is designed to blend seamlessly into a wide range of Arai motorsport and karting helmets. Whether your shell retains its original factory finish or features a complex, multi-layered custom paint layout, the transparent material allows the underlying graphics or raw shell colour to show through beautifully. For drivers with bespoke livery designs, the high-grade plastic can also be custom-painted to match your exact team colour scheme perfectly.

Key Performance Features

• Genuine Arai Product: An authentic factory-produced accessory manufactured to Arai's uncompromising quality and safety standards, guaranteeing a perfect contour-matched fit.
• Extensive Helmet Compatibility: While designed as a direct replacement for the legacy Arai GP-5K series, this adaptable duct is sculpted to fit various current and older full-face models across the Arai motorsport lineup.
• Optimised Cockpit Cooling: Actively channels high-velocity oncoming air into the helmet’s upper internal pathways, helping to displace stagnant heat and prevent humidity build-up during intense race stints.
• Heavy-Duty Self-Adhesive Strips: Supplied complete with ultra-strong, pre-cut double-sided adhesive fixing strips, making the trackside installation process exceptionally fast, secure, and straightforward.

Please Note: This listing is for a single set of top ducts with adhesive strips. For a permanent, track-safe bond, ensure that the helmet's application surface is completely clean, degreased, and entirely free from old adhesive residue, wax, or polish prior to fitting.
