Arrma 1/10 GRANITE MEGA 665 4X4 RTR Monster Truck Orange

Dominate the terrain with the 1/10 scale ARRMA GRANITE MEGA 665 4X4 — a ready-to-run (RTR) brushed monster truck engineered for out-of-the-box performance and all-terrain fun. Featuring enhanced durability, increased power, and upgrade-ready design, the GRANITE MEGA 665 delivers serious bashing action with confidence.

Built Tough. Designed to Grow.

Powered by an all-new MEGA 665 high-torque brushed motor, which is 11% larger than its predecessor, this beast comes equipped with an aluminum heatsink and a 35mm cooling fan to maximize power and efficiency. The robust 3S brushless-ready transmission makes upgrading to brushless power a breeze — no modifications needed.

A maintenance-free overload coupling protects the drivetrain by absorbing excess torque, replacing the traditional slipper clutch for reduced upkeep and enhanced reliability.

All-Terrain Dominance

From gravel to grass, the GRANITE MEGA 665's oil-filled, coil-over shocks and rugged all-terrain suspension deliver exceptional handling. Tackle uneven surfaces with confidence thanks to adjustable ride height and dBoots FORTRESS MT tires that grip across multiple surfaces. Extended side guards on the durable composite chassis keep debris out and critical components clean.

Aggressive Looks, Smarter Design

The GRANITE’s factory-finished monster truck body comes in bold new colors and now features a clipless body retention system for cleaner lines and easy access. Impact-absorbing bumpers and a ventilated chassis boost durability while maintaining a lightweight design.
