Pair of composite molded surprise pistons for 2 surprise absorbers with eight 1.2mm holes & two 1.2mm holes. Two-way motion shock pistons work in different ways once the piston travels up or down. Utilizing the artificial valve setup regarding piston, 2 holes are closed whenever piston travels up
appropriate the piston travels down, the valve begins 2 extra holes which means that your oil methods through 10 holes completely. This setup enables perfect landings from jumps, despite a soft shock set-up. Created from specially-formulated composite item to give you smooth action & durability. Well-proven molding procedure guarantees perfect piston roundness after production, which means that your pistons move totally in the shock systems for identical shock action in just about any four shocks.
