Compact, durable, and engineered for fun anywhere, the 1/18 scale ARRMA Granite Grom 4X4 Monster Truck in Red delivers big performance in a small size.

ATModels Bench & Track Notes
- Mini Bashing Performance: The Granite Grom sets a benchmark for 1/18 scale bashers. The metal differential gears handle aggressive back-and-forth throttle inputs on carpet, grass, and pavement without stripping.
- Charging Protocol: For optimal battery longevity, always use a standard 5V USB wall adapter (like a smartphone charger) with the supplied Spektrum Smart USB-C charging cable.
- Body Latch Maintenance: The clipless body mount system makes battery swaps effortless. Keep a small soft brush handy to clear out fine dirt around the release mechanism after running on dusty trails.
Key Features & In-Depth Engineering
- Complete All-In-One Box: Factory-assembled with Spektrum SLT2 2.4GHz radio, Spektrum 2S 1400mAh Smart LiPo battery, and Smart USB-C charger included.
- Rugged Metal Gear Drivetrain: Metal differential ring and pinion gears enclosed against sand, carpet lint, and gravel.
- Clipless Quick-Release Body: Secure body latching system allows instant battery access without fiddly body clips.
- Oil-Filled Suspension: True oil-filled shocks absorb jumps and bumps far better than basic friction springs found on competitor mini trucks.
- Safe Throttle Control: Transmitter includes a throttle limiting switch (50% and 75% modes) allowing beginners to build driving confidence safely.
- Waterproof Electronics: Sealed Spektrum 2-in-1 receiver/25A ESC and metal-geared Spektrum SX110 micro steering servo.
