This is an optional XRAY Conical Shock Piston Set, and is intended for use with the XRAY XT8 and XB808 family of vehicles. This set Set of composite molded 8- and 10-hole shock pistons feature a conical shape for smoother damping. Four 8 hole pistons are included, a pair of 1.2mm hole pistons, and a pair of 1.3mm hole pistons. The different-sized holes allow you to tune the damping characteristics of the shocks. This set also includes a pair of 10-hole pistons that feature 1.1mm holes.
These big-bore pistons are manufactured from well-proven, specially-formulated composite material to provide smoother action and increased durability. The well-proven molding production process is used to ensure perfect roundness of the pistons after production, so that the pistons will move perfectly inside the shock bodies for identical shock action in all four shocks.
