This is a set of (4) CSI/Traxxas 10MM Oval V-Port Pistons. They are available in two flow rates. The CSI (BLUE) Oval V-Port pistons should be used on smooth high bite track surfaces (Indoor), while the CSI (RED) Oval V-Ports are to be used on tracks that are rough and provide less bite (Outdoor). CSI's uniquely engineered 2 Oval V-Port design is optimal for 10MM bore size shocks, providing separate compression and rebound damping depending on which direction the piston is installed. CSI's 10MM Oval V-Port pistons are compatible with Power Stroke Shocks.
