The new aluminum double-effect shock pistons for Kyosho, Hot Bodies and Gs Race cars are really very effective.
The 16mm external diameter is perfect for the cylinder barrel of the above mentioned models, assuring smoothness and extreme precision.
The innovation is the anti-sinking system, that is an o-ring placed on the external part of the pumping unit; the nose cone holes streamline the silicon oil flow towards the latter, which opens when the car encounter deep holes or has to spring. In this way the model car never hits the ground with the chassis while keeping a regular attitude.
Even swifter and more regular cars thanks to this new part, a must-have for the best pilots.
