A bigger, tougher KRATON® 4X4 4S BLX
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 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 the inclusion of steel gearbox input gears, steel main diff gears and CVD Driveshafts. Upgrades are joined by proven features from before that deliver unstoppable performance in environments ranging from off-road, dirt, and grass to parking lots, paved and asphalt surfaces. These include a strong composite chassis and retained hinge pin plates; protective skid plates in front and rear; steering with more clearance for stones; a castellated slipper pad and sliding gear mesh; and rubber-shielded bearings throughout. The KRATON® 4X4 4S BLX also incorporates the signature ARRMA® easy-access modular design to make routine maintenance fast and simple.
Made of high-quality rubber, the dBoots® Copperhead 2 LP tires offer an aggressive, chunky tread pattern for excellent traction on a wide range of surfaces. They're also vented to disperse water for improved durability. The truck body has a tough, injection-molded rear wing and comes factory-finished in your choice of two exciting colors. Front and rear bumpers protect against impacts and a wheelie bar with rubber tires provides stunt potential.
Completing the ready-to-run package are a Spektrum™ SLT3™ 2.4GHz radio with SR315 receiver and a stronger, faster Spektrum™ S652 digital servo. Add your choice of battery, charger, and "AA" transmitter batteries and bash with the best!
For this new version of the KRATON® 4X4 4S BLX Speed Monster Truck, ARRMA® engineers lengthened the vehicle to 21.54 inches – 0.74 inches longer than previous model — for increased stability and control.
To handle more aggressive bashing, the front and rear track width has been increased with new, wider arms to 17.72 inches – 1.89 inches more than the previous KRATON® 4X4 4S BLX Speed Monster Truck.
Features that contribute to the 4X4 4S BLX platform's unstoppable performance include a stronger composite chassis and retained hinge pin plates; protective skid plates in front and rear; steering with more clearance for stones; a castellated slipper pad and sliding gear mesh; and rubber-shielded bearings throughout. Extended height dirt defenders limit the amount of dirt and debris that can reach the chassis tub. Front and rear bumpers offer defense against impacts.
The KRATON® 4X4 4S BLX Speed Monster Truck RTR incorporates the signature ARRMA® easy-access modular design. Separate, easily removable chassis modules for the power system, electronics and differential components make routine maintenance fast and simple.
BIG BORE OIL-FILLED SHOCKS
Longer, aluminum-bodied, oil-filled big bore shocks are included and mounted on higher shock towers. These plus the wider suspension arms give the vehicle longer, more plush suspension travel.
WHEELS & TIRES
The high-quality rubber 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 wheels with CNC machined, red anodized 17mm hubs.
STEEL INPUT & MAIN DIFF GEARS
The input and main differential gears are now manufactured from steel. Combined with the steel internal differential gears these provide an extremely strong transmission for the KRATON® 4X4 4S BLX Speed Monster Truck.
CVD SLIDER DRIVESHAFTS
The driveshafts on the KRATON® 4X4 4S BLX Speed Monster Truck are now a CVD design. These feature strong, hard wearing steel couplings and axles. The sliders are manufactured from a tough, impact absorbing composite material.
