Go from budget-friendly basher to hard-core beast with your first remote control monster truck, the ARRMA GRANITE 4X2 BOOST 550 MEGA Brushed 2WD. This big RC truck is ready-to-run and easy to afford, with only a battery and charger required. But the included MEGA brushed power system can still send it to 30+ mph under optimum conditions, and the tough composite chassis takes on off-road, dirt, grass, parking lot, paved and asphalt surfaces all without breaking a sweat. If anything goes wrong, get back on track in a snap thanks to the easy-to-maintain modular design exclusive to ARRMA RC cars and trucks — every on-board component is instantly accessible. The included Spektrum radio also has what new drivers of fast RC trucks need. You can limit the throttle to 50% or 75% of full power until you’re prepared for extreme speed. Of course, you won’t be a new driver for long. The ARRMA GRANITE 4X2 BOOST 550 MEGA Brushed 2WD is ready when you are for monster truck RC action, amplified! It’s brushless-ready, so you can easily upgrade to a 3S brushless motor system and go from bashing to all-out blasting. And with the 4X4 BOOST Transmission Upgrade Set (ARA210003, sold separately), the extra traction of 4-wheel drive is just ten minutes and three simple steps away!

The 1/10 scale GRANITE 4X2 BOOST 550 MEGA Brushed 2WD monster truck incorporates the signature ARRMA easy-access modular design. Separate, easily removable chassis modules for the power system, electronics, and differential components make routine maintenance fast and simple.




Contributing to the GRANITE 4X2 BOOST monster truck's unstoppable performance are a strong composite chassis; steering with more clearance for stones; a castellated slipper pad and sliding gear mesh; and rubber-shielded bearings throughout. Extended height dirt defenders limit the amount of dirt and debris that can get into the chassis tub.




Using the 4X4 BOOST Transmission Upgrade Set (sold separately), the 1/10 scale GRANITE 4X2 BOOST 550 MEGA Brushed 2WD monster truck can easily be upgraded for the extra traction of 4-wheel drive in just three simple steps.




The 1/10 scale GRANITE 4X2 BOOST 2WD monster truck is based on the proven ARRMA 4X4 platform. That means you can easily upgrade from its included 550 MEGA brushed power system to 3S brushless power whenever you are ready for the increased performance.




Tough, multi-spoke black MT wheels with vented, multi-terrain dBoots Fortress MT tires give the GRANITE 4X2 BOOST 2WD effective traction for bashing almost anywhere, from dirt and grass to parking lots, paved, and asphalt surfaces.




The included Spektrum SLT2 transmitter is perfectly balanced for fatigue-free bashing and has a foam wheel for precise fingertip control. New bashers can set the throttle limits at 50% or 75% until ready to use the full speed potential.
