Discover the ARRMA Granite Grom | Mighty RC Fun in Mini Form
RC Thrills Wherever You Go
Experience high-energy RC excitement in a compact form with the ARRMA Granite Grom 4X4 Monster Truck. This 1/18 scale powerhouse packs the same punch, durability, and performance you’d expect from ARRMA – now in a more travel-friendly size.
Perfect for after-school meetups or a quick midday blast, the Granite Grom slides effortlessly into your routine. It’s speedy, it’s solid, and it’s built for instant RC enjoyment whenever and wherever.
Compact Build, Serious Muscle
Unlike many mini RC vehicles, the ARRMA Granite Grom delivers without compromise. Crafted with the same attention to detail as its larger counterparts, it boasts a clip-free body for quick access and a tough structure made for action-packed fun.
Fitted with tough bumpers at the front and rear, a sturdy composite chassis, and a robust 4WD transmission featuring metal gears, this small monster is ready to take on the rough stuff. Plus, with waterproof electronics onboard, you can keep going rain or shine.
User-Friendly Smart Features
New to the RC scene? The included Spektrum SLT2 controller makes it simple to get started. Adjustable speed settings (50% or 75%) let you ease into driving until you’re ready for full power. Recharging is just as simple – plug the included Smart 2S LiPo battery into the USB-C charger and let the built-in tech do the work.
Ready to Run, Straight Out of the Box
No need for extras – the Granite Grom comes fully equipped. Choose from three bold colour schemes and enjoy everything you need right in the box: electronics, LiPo battery, charger, and even AA batteries.
