[Parts that are useful for improving the performance and maintenance of RC cars]
Silicone material with a good balance of expandability and lubricity is used to maintain the performance of the oil damper for a long time.
The material hardness is 30 ��. which is excellent for the initial movement of the oil damper. Ideal for electric RC touring cars.
In addition. there is little air biting after running (a state in which air is drawn into the cylinder by the vertical movement of the damper shaft). and stable damping performance is demonstrated.
The color is navy blue.
