Features 1、Made of high quality aluminum alloy materials, effectively reduce the vibration of the remote control car and improve its performance. 2、The spring is a rebounding medium, and there is a small hole at the bottom of the insert. When pressure is applied, the hydraulic oil can be pressed into the hole to achieve the shock absorbing effect. 3、When the pressure disappears, the spring will change the shock damper into the shape before deformation, the real negative pressure effect. 4、CNC machining makes it perfect size, stable performance, anodized blue, double spring design, adjustable damping. 5、Reasonable design, strong cushioning, perfect matching model as replacement of original parts.
