Group of composite molded 8- and 10-hole surprise pistons for two surprise absorbers. 8-hole pistons can be found with 2 different-sized holes (1.2 and 1.3mm) for changing damping (2 per piston). 10-hole pistons are available with 1.1mm holes. These pistons are conical for smoother damping.
Big-bore pistons are made of well-proven specially-formulated composite product to present smoother action and durability. The well-proven molding production procedure can be used to make certain perfect roundness of this pistons after manufacturing, so that the pistons will move completely inside the shock figures for identical surprise action in most four shocks.
