Set of composite molded 6-hole shock pistons for 2 shock absorbers. Pistons are available with 3 different sized holes for changing damping: 1.3, 1.4, and 1.5mm holes (2 per piston). Big-bore pistons are manufactured from well-proven specially-formulated composite material to provide smoother action and 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.
