This is a set of CSI's New Squared V-Port Delrin Pistons. These pistons share some of the same engineered features as our first generation Varying Port design. Through rigorous testing both on track and using CSI's state of the art Shock Dyno, CSI engineers have taken 1/8 scale off road shock performance to a whole new level. CSI's Squared V-Port pistons provide two separate flow rates for compression and rebound damping. They have been specifically engineered to provide superior performance on tracks that produce higher shaft velocities. The rebound side of CSI's Squared V-Port piston has been engineered and precision CNC machined to reduce the "packing effects" of the shock when higher velocities are achieved, allowing the tire to get back to the surface and absorb the next bump or series of bumps. CSI Squared V-Port Pistons are offered in two flow rates, our base line piston (Blue) for average track surface conditions and our (Red) piston that should be used for rougher track surface conditions. Track conditions and vehicle set-up will determine final oil viscosity used.
