Group of composite molded shock pistons for two shock absorbers with six 1.4mm holes & two 1.1mm holes. Two-way movement shock pistons work in different ways whenever piston travels up or down. With all the plastic valve set up regarding the piston, 2 holes are closed whenever piston travels up
when the piston travels down, the valve starts 2 extra holes therefore the oil moves through 8 holes in total. This configuration enables perfect landings from jumps, even with a soft surprise set-up. Constructed from specially-formulated composite material to present smooth action & durability. Well-proven molding procedure ensures perfect piston roundness after production, so that the pistons move completely in the surprise systems for identical shock action in all four shocks.
