Everything in one box, programmed on the same channel, tested together before it ships. If you are starting from zero this is where to start — you will not end up with a radio that does not match your harness or an antenna that will not mount to your car.
Packages run from a simple two-way starter kit to full digital team systems. Not sure which tier you need? Read our Good, Better, Best guide.

A car-to-crew system is three groups of parts that have to match each other. Once you can see how they connect, choosing gets a lot easier.
In the car
A mobile radio mounts in the car and runs off car power. The in-car harness is the wiring that ties the radio, the driver and the push-to-talk together. The push-to-talk button mounts on the wheel or on a bracket within reach of the driver's hand. An antenna, coax and mount carry the signal out of the car — this is the part people most often under-spec, and antenna choice and mounting location affect your real-world range as much as the radio does.
On the driver
A helmet kit puts a microphone and either earbuds or helmet speakers inside the driver's helmet. Kits are wired for a specific connector — IMSA / S9 is the most common, with NASCAR and off-road variants — so this is the piece to match to your car harness before anything else. A coil cord runs from the helmet to the car. Earbuds seal out more engine noise and are worth it in a loud car; helmet speakers are simpler to live with and easier to share between drivers.
With the crew
Each person on the crew needs a handheld radio and a headset. Over-the-head or behind-the-head crew headsets with a coil cord are standard on the pit box, and a spotter usually runs the same setup. Once you are past two or three radios, a bulk charger saves a lot of hunting for batteries.
Which setup fits you
Circle track and drag racing. One driver, one or two crew, short runs. An analog 5-watt in-car radio, a helmet kit, a push-to-talk, a roof-mount antenna and a couple of crew radios covers it. This is the least expensive way to get real driver-to-crew communication in the car.
Road course and club racing. Longer sessions and usually a spotter. Same core system, but it is worth stepping up the antenna and adding a dedicated spotter headset. Many teams add a scanner so someone can monitor race control at the same time.
Endurance and multi-driver. Driver changes make the helmet side the bottleneck: every driver needs their own helmet kit, and every kit has to use the same connector as the car. A 20-watt digital in-car radio holds up better over long stints, and a bulk charger keeps the crew running through a night race.
Two-seat and intercom cars. Rally, off-road, instruction cars and airboats need driver-to-passenger talk on top of outside communication. An intercom handles the in-car side, and the radio plugs into it so both people hear the crew.
Every package on this page ships programmed and tested, working together. If you are still not sure which one fits, tell us what you drive and who needs to hear whom, and we will put the list together for you.
