Add Oil to Shocks

Shocks and springs are part of the suspension in RC vehicles. Oil-filled shocks give RC vehicles more stability over rough terrain. Without the oil the shocks compress and rebound too quickly and fail to absorb or dampen the bumps in the road. When you feel that your shock absorbers aren't performing properly you can check the fluid level and add more oil to the shocks.

Shock oil comes in different weights such as 40, 70, or 100. Ask your hobby shop sales associate for recommendations based on your car/truck and the conditions under which you run it. Changing the weight of the oil changes the damping rate -- the compression of the shock -- so that you can finetune it for different road or track conditions.
