Overview

With massive tires, a menacing truck body, and a long wheelbase for stability, the 1/10 scale ARRMA KRATON 4S BLX Speed Monster Truck proudly takes its place between agile 3S BLX bashers and mighty 6S BLX machines. The 4S BLX platform lets you bash with next-level ARRMA performance, toughness, and speed, without breaking your budget. 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.

Fully ready-to-run, the ARRMA KRATON 4S BLX Speed Monster Truck comes with a 3-channel Spektrum SLT3 2.4GHz radio and dual protocol SR315 receiver. Charge up your choice of recommended battery and blast with the best!

Video Overview

METAL CENTER DIFFERENTIAL

All-metal EXB gear diffs give the KRATON 4S BLX Speed Monster Truck EXtreme Bash durability. An aluminum-cased center differential has also been added that provides the ultimate traction in any surface conditions.

MODULAR CHASSIS DESIGN

Separate, easily removable chassis modules for the power system, electronics and differential components make routine maintenance fast and simple. The KRATON 4S BLX chassis has been updated to accept a center diff module, and also now includes hinge pin bracing and a dirt drain.

OIL-FILLED SHOCKS

Long, aluminum-bodied, oil-filled shocks with silicone O-rings are mounted on high shock towers. These plus wide suspension arms give the KRATON 4S BLX the plush suspension travel needed to soak up bumps.

INCREASED DIRT PROTECTION

With dirt guards for the wishbones, outdrive protectors, and taller side guards all added for extra protection against the elements, the KRATON 4S BLX is more prepared than ever for high-speed, all-road blasting.

dBOOTS COPPERHEAD 2 LP TIRES

The dBoots COPPERHEAD 2 LP tires are vented to disperse water for improved durability. Their multi-surface, chunky tread pattern delivers awesome traction on a wide range of surfaces. The tires are mounted on tough, 3.8” MT black multi-spoke wheels with CNC-machined, red-anodized 17mm hubs.

FINISHED TRUCK BODY

The sleek truck body features a tough, injection-molded rear wing and comes factory-finished in your choice of two exciting color schemes. Front and rear bumpers protect against impacts and a wheelie bar with rubber tires provides stunt potential.

SPEKTRUM S662 STEERING SERVO

The installed Spektrum S662 digital, waterproof steering servo easily handles the demands of high-speed, all-road blasting with full metal gears and high torque (236 oz-in @ 7.4V). It also features an industry-standard 25T spline servo horn.

SPEKTRUM BRUSHLESS POWER SYSTEM

The brushless power system includes an efficient Spektrum Firma 2400Kv brushless motor matched to an updated, cool-running Spektrum Firma 120A Smart V2 waterproof ESC with IC5 connectors (also compatible with EC5 connectors). The KRATON 4S BLX can reach speeds of 55+ mph with a 4S LiPo battery and optional pinion gear, available separately.

SPEKTRUM SLT3 2.4GHz 3-CHANNEL TRANSMITTER

The included Spektrum SLT3 transmitter is ergonomically designed for fatigue-free bashing and has a foam wheel for precise fingertip control. Using the throttle limiting function, new RC drivers can limit top speed to 50% or 75% of the monster truck’s full potential until they’re ready to unleash it all.

SPEKTRUM SR315 3-CHANNEL DUAL PROTOCOL RECEIVER

Compatible with SLT and DSMR protocols, the included Spektrum SR315 3-channel receiver offers outstanding range and fast response rate. It’s also Smart telemetry compatible (in DSMR mode and using the Spektrum Dashboard app).
