Pair of composite molded shock pistons for two shock absorbers with five 1.5mm holes & two 1.0mm holes. Two-way flow shock pistons work with other ways once the piston travels up or down. Utilizing the rubber valve installed regarding piston, 2 holes are closed whenever piston travels up
then when the piston travels down, the valve starts 2 extra holes so the oil flows through 7 holes as a whole. This configuration enables perfect landings from jumps, despite a soft surprise set-up. Made of specially-formulated Delrin composite material to present smooth action & durability. Well-proven molding process guarantees perfect piston roundness after manufacturing, so the pistons move completely within the surprise figures for identical shock action in most four shocks.
