Pair of composite molded shock pistons for 2 surprise absorbers with six 1.4mm holes & two 1.1mm holes. Two-way flow shock pistons work with different ways as soon as the piston travels up or down. With the rubber valve set up on piston, 2 holes are closed when piston travels up
proper the piston travels down, the valve starts 2 additional holes so that the oil moves through 8 holes in total. This setup enables perfect landings from jumps, despite having a soft surprise set-up. Constructed from specially-formulated composite material to deliver smooth action & durability. Well-proven molding process ensures perfect piston roundness after manufacturing, so that the pistons move completely within the surprise bodies for identical shock action in all four shocks.
