Band of composite molded surprise pistons simply for two surprise absorbers with five 1.5mm holes & two 1.0mm holes. Two-way movement shock pistons work in various ways in the event that piston travels up or down. With the plastic valve setup on piston, 2 holes are closed whenever piston travels up
appropriate the piston travels down, the valve starts 2 additional holes and so the oil moves through 7 holes as a whole. This setup enables perfect landings from jumps, despite having a soft shock set-up. Made of specially-formulated Delrin composite item to give you smooth action & durability. Well-proven molding procedure guarantees perfect piston roundness after manufacturing, thin pistons move completely inside the shock systems for identical shock action in most four shocks.
