Arrma Kraton 1/10 4x4 BLX 4S Brushless RC Monster Truck - V2

The KRATON® 4X4 4S BLX Speed Monster Truck RTR marks the next evolution of the ARRMA® 4X4 4S platform — longer, wider, and tougher than the previous chassis for no-holds-barred bashing action, with a Spektrum™ 4S brushless power system factory-installed.

The original ARRMA® KRATON® 4X4 4S BLX Speed Monster Truck provided the perfect middle ground between the agile 3S BLX vehicles and bigger, more powerful 6S BLX machines. It delivered affordable performance for brushed bashers looking to upgrade and for any driver wanting ARRMA® toughness and speed.

This new version marks the next evolution of the capable ARRMA® 4X4 4S platform — longer, wider, and tougher than the previous chassis for even greater stability and control. It also includes a full package of Spektrum™ radio electronics and is the first ARRMA® 4X4 to come equipped with a Spektrum™ 4S brushless power system.

The Kraton 4S reinforced chassis features a center diff module for unrivalled traction, while wishbone dirt guards, out-drive protectors, and taller side guards shield it while bashing.
