The STX2® 2-channel radio that drives the GRANITE™ 4X4 3S BLX RTR has many of the same features found in high-end 2.4GHz radio systems —throttle and steering reversing, throttle and steering travel adjust, throttle limiting and more. It's paired with a factory-installed SRX200 2-channel waterproof receiver.


The new RC system launches you confidently into terrain-commanding monster truck excitement. Tough components, awesome 3S BLX power, and high-quality ARRMA® engineering conquer anything that stands in your path. The GRANITE™ 4X4 3S BLX finds unrivaled traction on any surface as it carves the landscape with ground-thrashing full-time 4WD. Precision aluminum, tough steel, and composite materials all combine to make this brushless monster a vehicle that's ready for hard-hitting action, right out of the box.


Power, electronics, and front and rear differential modules are simple to access and can be removed quickly for maintenance. They make sure you spend more time bashing and as little as possible in the workshop. The main differential gears have been super-sized with TOUGH, large pitch gears to withstand huge torque. The differential internals feature full-metal, straight-cut gears for equally trouble-free operation.


Built to soak up intense all-weather thrills and spills with its independent suspension and oil shocks, the GRANITE™ 4X4 3S BLX handles it all — everything from fast speed runs to snow and mud chucking. No matter where you bash, you'll remain stable and in control. The shocks feature a keyed spring perch and self-bleed design. They're simple to maintain, yet offer the performance necessary for amazing all-terrain handling.


Four dBoots® FORTRESS tires on black chrome multi-spoke wheels give the GRANITE™ 4X4 3S BLX superb bite on a multitude of surfaces. ARRMA® has also installed an adjustable multi-height wheelie bar as standard.

The aggressively styled truck body looks great while bashing and even better up-close and personal, with great attention to detail on the decal and body aesthetics. Choose orange or red trim schemes. The ARRMA® GRANITE™ 4X4 3S BLX RTR requires only a battery, charger, and AA transmitter batteries.
