Set of composite molded surprise pistons for two surprise absorbers with eight 1.2mm holes & two 1.2mm holes. Two-way movement shock pistons work in various ways once the piston travels up or down. With the plastic valve installed regarding piston, 2 holes are closed whenever piston travels upÂ… appropriate the piston travels down, the valve starts 2 extra holes so the oil flows through 10 holes altogether. This configuration allows perfect landings from jumps, even with a soft shock set-up. Made out of specially-formulated composite material to give you smooth action & durability. Well-proven molding procedure guarantees perfect piston roundness after production, so your pistons move completely within the surprise systems for identical shock action in almost every four shocks.
