Reinforced Aluminum Alloy Chassis
The SCY 18103 1/18 4WD RC Short Course Truck features a reinforced aluminum alloy bottom plate that adds both strength and rigidity to the frame. This structural upgrade minimizes chassis flex during high-speed cornering and heavy landings, allowing smoother handling on uneven terrain. The alloy reinforcement also helps distribute impact force evenly, reducing wear on drivetrain components and improving long-term durability.

Adjustable Metal Shock Absorber System
Equipped with full-metal adjustable shock absorbers, the SCY 18103 delivers excellent damping response and stability over rough terrain. Each shock includes a removable spring washer design, allowing drivers to fine-tune hardness and rebound characteristics for different driving styles—whether high-speed bashing or precision cornering. This advanced suspension design helps the truck maintain traction and balance even on rocky or uneven ground.

All-Terrain Tires & Metal Wheel Hubs
The truck rides on anti-slip, wear-resistant off-road tires paired with metal wheel hubs secured by screw locks. This setup provides a solid grip and prevents tire separation under high torque or intense cornering. Designed for multi-terrain adaptability, the SCY 18103 performs equally well on asphalt, gravel, and sand—making it an ideal all-rounder for both beginners and experienced RC enthusiasts.
