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. 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 footprint of this KRATON 4X4 4S BLX Speed Monster Truck is 16% larger than the previous model, with higher shock towers, longer shocks, and wider suspension arms for longer, more plush suspension travel. The strength of the transmission has been bolstered with steel gearbox input gears, steel main diff gears and CVD driveshafts. The KRATON 4X4 4S BLX incorporates the signature ARRMA easy-access modular design to make routine maintenance fast and simple.
