RaceCom IMSA Female to Mono 3.5mm Adapter Cable
The RaceCom IMSA Female to 3.5mm Adapter Cable is the clean, purpose-built solution for connecting your IMSA-style helmet kit to a Raceceiver or any mono 3.5mm receiver. Available in 12" and 36" lengths to suit different cockpit configurations, this straight-cable adapter eliminates signal compromise at the connector. If your radio system runs an IMSA Female plug and your series mandates a Raceceiver, this is the link in the chain you don't want to get wrong.

- IMSA Female to mono 3.5mm male — correct plug pairing for connecting IMSA helmet kits to Raceceiver-compatible receivers
- Mono 3.5mm wiring — properly configured for Raceceiver use; not a stereo cable, ensuring full audio on compatible devices
- Two length options — 12" for compact cockpit routing; 36" for dash or cage-mounted receiver setups
- Straight cable design — minimizes connector strain and fits neatly within the cockpit without awkward bends
- RaceCom construction quality — built to the same standard as RaceCom's professional communication systems used in IMSA competition
- Plug-and-play installation — no modification required; connects directly between your helmet lead and mono 3.5mm input
When your radio setup runs an IMSA Female connector and your series requires a Raceceiver or similar mono 3.5mm device, you need a dedicated adapter — not a workaround. The RaceCom IMSA Female to 3.5mm Adapter Cable is engineered specifically for this application, delivering a clean, low-resistance connection between your helmet kit and receiver without signal degradation or connector stress.
The straight 3.5mm male plug is wired mono — the correct configuration for Raceceiver compatibility. This is not a stereo cable, and that matters: plugging a stereo 3.5mm into a mono Raceceiver will result in audio on only one channel or no audio at all. RaceCom builds this cable to spec so you're race-ready from the moment it's installed.
Choose between 12" and 36" cable lengths depending on where your radio or Raceceiver mounts relative to your helmet connection point. The shorter 12" works well for tight in-helmet or near-helmet routing, while the 36" gives you reach for dash or roll cage-mounted receivers. Both lengths use the same robust construction and IMSA Female termination that RaceCom is known for across their professional-grade communication lineup.
Trusted by IMSA competitors and road racers who can't afford a communications failure during a stint, this adapter is a straightforward fix to a very specific problem — and it works.
