If you’re looking for your first hobby-quality RC basher vehicle, nothing else compares to ARRMA® 4X2 BOOST 550 MEGA Brushed 2WDs. It’s not just the characteristic ARRMA speed and durability that sets them apart. Based on the proven ARRMA 4X4 platform, ready-to-run 4X2 BOOST 550 MEGA Brushed 2WD vehicles can be upgraded easily to 4-wheel drive and 3S brushless power whenever you’re ready. What’s more, they also offer great value.
Even without those upgrades, the GRANITE™ 4X2 BOOST 550 MEGA Brushed 2WD monster truck can reach speeds of 30+ MPH in optimum conditions using optional gearing. For all-terrain toughness, it includes a strong composite chassis and retained hinge pin plates; steering with more clearance for stones; a castellated slipper pad and sliding gear mesh; and rubber shielded bearings throughout. The GRANITE™ 4X2 BOOST is engineered to outlast other beginner-level bashers.
It retains the ingenious modular chassis design perfected by ARRMA engineers for easy component access. Separate, easily removable modules for the power system, electronics, and differential components make routine vehicle maintenance fast and simple.
The self-bleeding, oil-filled shocks with silicone O-rings use a tried and tested, coil-over design for effortless maintenance and amazing handling. Their innovative rod-end has a molded-in spring perch for extra toughness. High chassis guards limit the amount of dirt and debris that can get into the chassis tub. Shock-absorbing loops keep the front and rear bumpers secured to the chassis, offering defense against heavy impacts.
The GRANITE™ 4X2 BOOST 550 MEGA Brushed 2WD monster truck comes with the Spektrum™ SLT2™ transmitter and SLT™ 2-in-1 40A ESC and receiver. The transmitter is ergonomically designed for long periods of fatigue-free driving and has a foam wheel for precise fingertip control. New drivers will be able to set throttle limits at 50% or 75% until ready to unleash the full speed potential.
Tough, multi-spoke black MT wheels with vented dBoots® Fortress™ MT tires give the GRANITE™ 4X2 BOOST 550 MEGA Brushed 2WD effective traction for bashing on almost any terrain — including off-road, dirt, grass, parking lots, paved and asphalt surfaces.
The GRANITE™ 4X2 BOOST is brushless-ready, so you can easily upgrade from its included 550 MEGA brushed power system to 3S brushless power whenever you’re ready for the increased performance. And with the 4X4 BOOST Transmission Upgrade Set (ARA210003, sold separately), the extra traction of 4-wheel drive is just three simple steps away!
