Group of composite molded shock pistons for just two shock absorbers with five 1.5mm holes & two 1.0mm holes. Two-way movement shock pistons work in different ways when the piston travels up or down. With all the plastic valve set up on piston, 2 holes are closed whenever piston travels up
proper the piston travels down, the valve opens 2 extra holes so the oil moves through 7 holes in total. This setup allows for perfect landings from jumps, even with a soft surprise set-up. Constructed from specially-formulated Delrin composite product to offer smooth action & durability. Well-proven molding process ensures perfect piston roundness after production, so the pistons move completely within the shock bodies for identical surprise action in every four shocks.
