If your YIKONG YK4061 RC car shows a noticeable axle effect, don’t worry. Since this model has a larger scale, a visible axle effect is quite normal.
You can optimize the performance with the following adjustments:
- Tighten the shock springs slightly – to increase suspension support;
- Use higher-viscosity shock oil – to enhance damping and reduce the axle effect.

With these adjustments, you can effectively improve the handling stability and off-road performance of your YIKONG YK4061 crawler car.
