Premium RC Monster Truck Off-Road Racing Kit

Built for drivers who crave true retro monster truck attitude with modern race engineering, the Reactor Stage 2 "Wolf" Racer Edition 1/10 4x4 delivers the perfect blend of scale realism, 13-inch wheelbase stability, and competition-ready performance — giving you a chassis that looks right, jumps flatter, tracks straighter, and is always ready to crush, race, or freestyle on demand.


Extended 13-Inch Wheelbase Performance

The 13.00” wheelbase gives the Reactor Stage 2 "Wolf" Racer Edition a balanced, scale-correct stance while dramatically improving straight-line tracking and jump predictability. The longer chassis jumps flatter, slows fore-and-aft bounce cycles, and gives drivers more time to react to take-offs and landings, making it ideal for controlled racing and freestyle-style driving.


Competition-Ready Retro Platform

Built as a true competition-inspired 1:10 retro monster truck kit, the Reactor is engineered for straight-line car crushing, U-turn layouts, Chicago-style racing, and figure-8 tracks. It blends race-bred design elements with classic monster truck character, offering a versatile platform to recreate iconic builds from past or present.


Premium Construction & Components

The kit features extremely lightweight and rigid carbon fiber chassis plates, all-aluminum oil-filled shocks, and a dual-shock leaf-spring suspension with solid straight axles just like full-size 1:1 monster trucks. Anodized aluminum hub carriers, suspension links, shackles, and hex adapters deliver durability, precision, and race-ready strength.


Dual Motor on Axle Drive

The innovative dual motors on axle system delivers impressive torque and smooth power delivery directly to the drivetrain. This layout improves traction and responsiveness while maintaining the controlled driving characteristics that make retro monster truck racing and technical driving so rewarding.


Driver-Focused Power Versatility

Designed for control rather than chaos, the Reactor performs exceptionally with a recommended 27T brushed motor setup while still supporting higher-power brushless systems if desired. This balanced approach lowers entry cost, sharpens driving skill, and creates a dependable 4x4 monster truck that’s always ready to crush, jump, and tackle varied terrain.
