Helmet Adapter Cables

Plug-and-Race Helmet Adapter Cables

Your comms are only as clear as the link between your helmet kit and intercom. Baja Racing Gear’s Helmet Adapter Cables collection unites every plug, coil, and quick-disconnect you’ll need to talk clean through silt, wind, and 800 horsepower. Whether you’re bridging Nexus 4-pin, 5-pin, TA5, IMSA, or Stilo WRC, these race-rated jumpers keep you keyed-up with zero crackle.

Baja-Proof Construction

Every lead is built from oxygen-free tinned copper and wrapped in silicone jackets that survive −40 °F mornings and 250 °F firewall heat. Gold-plated pins and IP-67 O-ring backshells keep corrosion out when you’re wading the wash at San Ignacio. We pull-test each assembly to 150 lbs and over-mold strain reliefs so your cable won’t tear loose when the wheel rips at full lock.

Instant Compatibility

Match any PCI, Rugged, Comlink RTX, FluidLogic or Trax Plus intercom to your helmet in under 30 seconds—no soldering, no pin swaps. Just identify the plug on your helmet harness and radio, pick the corresponding adapter, and you’re race-legal.

Quick Install Checklist

1. Route coil cords along steering shafts with heat-resistant spiral wrap.
2. Apply dielectric grease on pins; lock collars finger-tight only.
3. Keep one Nexus barrel coupler in the chase truck for emergency swaps.
