Pair of composite molded surprise pistons for two shock absorbers with eight 1.3mm holes & two 1.2mm holes. Two-way flow surprise pistons work in various ways as soon as the piston travels up or down. Utilizing the plastic valve set up in the piston, 2 holes are closed when piston travels up
proper the piston travels down, the valve starts 2 additional holes therefore the oil flows through 10 holes as a whole. This setup permits perfect landings from jumps, despite having a soft shock set-up. Made of specially-formulated composite material to produce smooth action & durability. Well-proven molding procedure ensures perfect piston roundness after manufacturing, so that the pistons move perfectly in the surprise figures for identical surprise action in most four shocks.
