This KRATON comes fully factory-assembled on the latest evolution of the 4S BLX — and it’s prepared to blast like never before!The strengthened, diff compatible chassis now includes a center diff module that holds an aluminum-cased center differential. It provides the ultimate traction for any surface conditions. Shielded to the max with wishbone dirt guards, outdrive protectors, and taller side guards, the KRATON 4S BLX stands up to furious blasting over dirt, through grass, and on paved surfaces, all with equal ease.ARRMA has amped up its 4S-capable Spektrum brushless power system for intense all-road action. A cool-running Spektrum Firma 120A Smart V2 waterproof ESC with IC5 connectors (EC5 compatible) adds punch and improves the driving feel. Steering has been strengthened with a higher torque Spektrum S662 metal-geared digital servo, sharpening the KRATON 4S BLX truck’s high-speed maneuvering capabilities.
These updates join a vast arsenal of proven ARRMA 4S BLX features — from high shock towers, long oil-filled shocks, and wide arms for plush suspension travel, to steel diff gears and EXtreme Bash CVD front and rear driveshafts for unstoppable power delivery. The KRATON 4S BLX also incorporates the signature ARRMA easy-access modular design to make routine maintenance fast and simple.
Made of high-quality rubber, the vented dBoots COPPERHEAD 2 LP tires have an aggressive, chunky tread pattern that finds a solid grip almost anywhere. The truck body has a tough, injection-molded rear wing and comes factory-finished in your choice of two fresh color schemes. Front and rear bumpers protect against impacts and a wheelie bar with rubber tires provides stunt potential.
