Pair of composite molded surprise pistons for two surprise absorbers with eight 1.2mm holes & two 1.2mm holes. Two-way flow surprise pistons work with other ways once the piston travels up or down. Using the rubber valve installed on piston, 2 holes are closed when piston travels up
proper the piston travels down, the valve starts 2 extra holes and so the oil moves through 10 holes altogether. This configuration enables perfect landings from jumps, despite a soft surprise set-up. Made of specially-formulated composite product to produce smooth action & durability. Well-proven molding process guarantees perfect piston roundness after production, so your pistons move perfectly inside the shock systems for identical surprise action in most four shocks.
