Couple of composite molded shock pistons for two shock absorbers with six 1.4mm holes & two 1.1mm holes. Two-way movement shock pistons utilize various ways when the piston travels up or down. Because of the plastic valve setup on piston, 2 holes are closed when piston travels up
proper the piston travels down, the valve begins 2 extra holes which means that your oil strategies through 8 holes all together. This setup enables perfect landings from jumps, despite having a soft surprise set-up. Made out of specially-formulated composite material to supply smooth action & durability. Well-proven molding procedure guarantees perfect piston roundness after production, so your pistons move completely inside the surprise systems for identical surprise action in many four shocks.
