Features
- "B" Competitive Edition Upgrades: Factory-upgraded with CNC-machined metal center transmission and transfer case housings, steel internal gears, metal drive plate, and vintage metal wheels.
- Torque-Compensating Reverse Rotation: Features a reverse-rotation drivetrain that counteracts chassis torque twist, keeping all four wheels gripping during steep climbs.
- Lightweight Polycarbonate SUV Body: The highly durable, clear Lexan SUV body minimizes weight above the chassis, keeping the vehicle's center of gravity (LCG) low for improved stability on inclines.
- Threaded Metal Shock Absorbers: High-quality, fluid-filled metal shock absorbers provide smooth damping and articulation over uneven rocky surfaces.
- Includes High-Torque 35T Motor: Comes with a factory-tuned 35T 540 brushed crawler motor, optimized for low-speed control and traction on inclines.
- Integrated LED Lighting System: Preconfigured with a responsive electronic LED lighting harness for controlling the headlights and scale marker lights.
- High-Traction Black Rock Tires: High-grip 115/45R 1.9" Black Rock crawler tires, paired with vintage metal rims and high-density foam inserts.
