Feature: 1. CNC Processing: CNC processing locking tires with weighted design can effectively reduce the gravity of the RC car and improve the performance of the RC car. 2. High Wear Resistance: RC wheel hub can provide strong road support, high wear resistance makes it able to withstand hard roads and rugged driving for a long time. 3. Reasonable Design: Reasonable design, weighted wheel hub increases the weight of the wheels, reduces the center of gravity of the vehicle and improves stability and maneuverability. 4. Increase Stability: Make the RC car more stable, no fear of any terrain, increase the stability of the tires, make your RC car cooler and more attractive. 5. Aluminum Alloy: RC car wheel hub is made of aluminum alloy material, safe and environmentally friendly, strong and durable, not easy to deformation, long service life.
