Overview

Amped-up ARRMA® RC blasting gets "fun-sized" with the fast, tough, and ready-to-run GRANITE GROM 4X4 Monster Truck. At 1/18 scale, it's small enough to take along anywhere. And the GRANITE GROM delivers a big dose of genuine ARRMA performance and durability whenever you get the urge to bash.

Enjoy some after-school RC monster truck action with friends. Sneak in a little bashing during your office lunch break. Whether you're a young beginner or an experienced RC basher, the GRANITE GROM easily fits time for ARRMA RC bashing into your way of life. It's tough, fast — and conveniently small.

Unlike many manufacturers of mini RC models, ARRMA made no compromises when shrinking this basher down to small scale size. The GRANITE GROM 4X4 Monster Truck is precision-engineered to the same high standards as larger ARRMA RC vehicles. It also has a clipless body mount design that keeps the body securely attached but easy to remove for all drivers, young and old. Among small scale RC basher models it's in a league of its own, with convenience plus the power, strength, and handling capabilities you need to get serious about your stunts.

The ARRMA GRANITE GROM 4X4 Monster Truck endures any punishment you can dish out. Impact-absorbing front and rear bumpers are the bash-ready bookends to its strong composite chassis. A 4WD transmission with robust metal spur and crown gears carries power from the MEGA 380 brushed motor through an enclosed drivetrain to the tough dBoots® FORTRESS monster truck wheels and tyres. Even the Spektrum SX110 steering servo has metal gears — and, like the IC2® connector-equipped Spektrum SLT 2-in-1 25A ESC and receiver, it's waterproof for carefree bashing in any conditions.

If you're a first-time RC basher, the Spektrum 2.4GHz SLT2 transmitter helps you learn control skills safely by limiting the monster truck's maximum speed to 50% or 75% until you're ready to handle it all. Recharging the included Spektrum Smart 2S LiPo battery is also worry-free. Just plug it into the supplied Spektrum S10 Smart G2 Mini 2S USB-C Charger with the attached IC2 connectors. Smart technology instantly takes care of the rest. In about an hour, your battery is safely recharged and ready for another round of fun.

Everything you'll need to the run the GRANITE GROM comes in the box. The truck body is professionally factory-finished in your choice of three brilliant, durable colour schemes. GRANITE GROM upgrade parts are available for cranking up its capabilities past eleven. They include a Metal Axle & Wheel Hub Set, Aluminium Shock Set, Adjustable Steering Links, and a two-piece, assembled Oil-Filled Differential Set.

Take advantage of small scale value and versatility with the GRANITE GROM 4X4 Monster Truck RTR, and experience ARRMA RC bashing excellence for yourself.

We want to ensure a smooth delivery experience for you, and here are some key details to keep in mind about our service.

  • For orders exceeding £120, delivery is available exclusively to mainland UK addresses. However, orders below £120 can be delivered to outlying Isles and Northern Ireland, provided they meet specific criteria: they must be deliverable by Royal Mail, weigh less than 30kg, and fit within the dimensions of 61cm x 46cm x 46cm. Please be aware that certain highland areas may entail additional delivery fees, as couriers often charge more for these deliveries. If you reside in the highlands or any outlying regions, we recommend reaching out to us before placing your order to verify delivery options and any potential extra charges.
  • Delivery is typically included in the price for the majority of our products, unless otherwise specified. However, please note that orders under £80 will incur an additional delivery charge. You can easily view this charge on the checkout page when finalising your purchase. We aim to maintain transparency in our pricing structure while providing you with the best possible service.
  • Most orders will be delivered via either a next working day delivery service or within 2 working days, depending on your chosen service. Please note that for next working day delivery, the cut-off time is 12pm, and dispatch occurs exclusively on weekdays. However, certain items may have longer shipping times, and the expected delivery period will be clearly specified in the product listing.
  • To streamline your order fulfillment process, please note that when your order includes items with varying shipping times, we follow this approach: If any item in your order has a longer shipping time, we will hold the entire order until all items are in stock. However, if certain items are expected to be restocked after a considerable delay, we offer you two options. You can choose to wait for complete fulfillment, where we'll dispatch the order once all items are back in stock. Alternatively, you have the option to receive a partial delivery, where we'll promptly send you the in-stock items and deliver the remaining items as they become available. Your satisfaction and convenience are paramount, and we strive to accommodate your preferences for multi-item orders.
  • To ensure efficient delivery, we work with trusted carriers: DPD Local for next working day delivery and Royal Mail for the 2 working days option.
  • After dispatching your goods, we'll promptly send you an email containing the parcel's tracking number. To ensure you stay updated conveniently, kindly provide a valid mobile number, which we will add to the consignment. This way, you can receive real-time updates on your mobile phone for added convenience.
  • For listings specifying a shipping time of "Dispatched within 3 working days," please note that orders under this category will typically be delivered within a timeframe of 3 to 5 working days.
