The ARRMA INFRACTION GROM 3S BLX 4X4 RTR brings the unmistakable street-bashing attitude of the full-size INFRACTION into a compact 1/12 scale package.
As ARRMA's first all-road street basher built on the GROM platform, this little powerhouse is designed to turn almost any stretch of pavement into your personal playground. Whether you're stepping up from your first RC car or you're already an INFRACTION fan looking for a compact addition to your fleet, the INFRACTION GROM 3S delivers serious speed, aggressive handling and plenty of attitude — straight out of the box.
3S Brushless Power – Two Levels of Chaos
The integrated PowerGuard speed-management system gives you two ways to experience the INFRACTION GROM 3S.
Straight out of the box, Adrenaline Mode delivers a confidence-inspiring 30+ MPH using the included 3S battery. It's an ideal starting point for newer drivers or anyone getting familiar with the car.
Ready to unleash the full potential? Insert the included PowerKey and activate Chaos Mode, unlocking verified speeds of 50+ MPH.
That's serious performance from a 1/12 scale RC car.
Spektrum DSC – Control the Slide
All that power is easier to manage thanks to Spektrum Dynamic Stability Control (DSC).
With four selectable settings — Off, Low, Medium and High — DSC automatically applies steering correction to help keep slides and high-speed manoeuvres under control.
Use maximum assistance while learning, reduce the intervention as your skills develop, or switch it off completely for full manual control.
ARRMA Tough, GROM Sized
Underneath the aggressive bodywork is a drivetrain designed to handle serious street abuse.
The enclosed 4WD drivetrain, sealed centre differential with metal spur gear and easy-access front and rear differentials help keep dirt out while delivering dependable power transfer.
A tough composite chassis, front and rear bumpers and an integrated body-location system help the GROM shrug off everyday impacts, while the low-slung chassis keeps it planted through high-speed corners.
The double-wishbone independent suspension and oil-filled shocks absorb bumps and impacts, while aluminium 12mm wheel hexes provide the strength needed for repeated hard launches.
Built to Own the Pavement
The INFRACTION GROM 3S comes equipped with dBoots Hoons white-compound belted tyres, providing the grip needed to put its 3S power down on the street.
The quick-release clipless body design makes battery changes and chassis access fast and convenient. The integrated SmartFit click-out battery system eliminates traditional battery straps, giving you a precise and secure fit every time.
A motor heatsink and cooling fan help manage temperatures during hard driving sessions.
Ready-to-Run – Everything Included
This is a genuine RTR package, meaning the major electronics, battery and charger are already supplied.
