Set of composite molded surprise pistons for 2 surprise absorbers with six 1.3mm holes & two 1.1mm holes. Two-way flow shock pistons work with other ways when the piston travels up or down. Aided by the plastic valve set up regarding piston, 2 holes are closed when piston travels up
proper the piston travels down, the valve opens 2 extra holes so that the oil flows through 8 holes in total. This setup enables perfect landings from jumps, despite having a soft shock set-up. Made of specially-formulated composite product to offer smooth action & durability. Well-proven molding process ensures perfect piston roundness after production, so your pistons move completely in the shock systems for identical shock action in every four shocks.
