So what role does the oil play in the shock? This is called ‘bottoming out,’ and it can cause severe damage to your car’s suspension. Without enough dampening in either the tube or the spring, the piston slams into the head of the tube. When the RC car drives over bumps, the shock absorber is compressed, causing the piston to travel up to the tube’s head. They cushion the effect of driving over rough terrain while stabilizing the car when cornering. They consist of a piston inside a tube filled with oil with a spring on the outside. The shocks on RC cars work like those on your real-life car.

This article will give an overview of oil weights and provide recommendations based on the type of RC car.įirst, knowing how a shock absorber works is essential to understand how different oil weights affect them. However, the wrong oil will increase your car’s response time, making it feel sluggish. The trick is to know what oil weight to put in your RC car’s shocks.Ĭhoosing the right oil can help you corner better and land easier after jumps. Changing the weight of the oil in your shocks improves performance and can extend their lifespan as well. Your RC car’s shock absorbers take a hammering running over rough terrain.
