Features

• Torque-resistant reverse gear: Features a highly advanced central transfer case configuration with integrated reverse gear to completely counteract axle torque twist, keeping all four wheels firmly on the ground, even at full throttle.

• CNC aluminum chassis construction: Built around a rigid, CNC-machined aluminum-alloy center brace and skid plate that virtually eliminate chassis flex during high-articulation maneuvers.
• Precision CNC shock absorbers: High-quality, fluid-filled metal CNC shock absorbers with special dual-pitch springs provide buttery-smooth compression and predictable rebound on uneven terrain.
• High-strength CNC suspension links: Equipped with heavy-duty CNC-machined aluminum-alloy links and robust steel rod ends for a lower center of gravity and excellent ground clearance.
• Aggressive Black Rock tires: Includes foam-filled "Black Rock" 115/45R 1.9 high-density all-terrain crawler tires, paired with retro-style metal wheels for a perfect balance of performance and realistic looks.
