The 1/7 scale ARRMA Big Rock 6S BLX is a monstrous RTR truck that combines extreme power with a beefy crew cab design. Built on the proven 6S BLX platform and equipped with high-quality Spektrum components, it delivers pure bashing pleasure—rugged, fast, and stylish.

The powerful Spektrum™ Firma 4074 2050kv brushless motor combined with the new 150A Smart V2 ESC enables speeds of over 105 km/h (65+ mph) with the included optional pinion gear. The IC5 connector system ensures optimal power transfer, while the entire setup is waterproof.

The anodized 6061-T6 aluminum chassis, adjustable shock absorbers with aluminum housings, and solid steel drive unit with EXB differentials make the BIG ROCK one of the most durable RC trucks in its class. The short body clips have been replaced with a modern clipless system – for quick access while maintaining a perfect appearance.

The truck is fully pre-assembled from the factory and comes with the proven Spektrum SLT3 2.4 GHz radio system and the SR315 receiver. The aggressive, ventilated dBoots RAGNAROK V2 tires guarantee grip on any terrain—from asphalt to gravel.
