The Kyosho IFW405-128 SP Shock Piston helps you dial suspension behaviour for better control. It is a sensible upgrade for tuners wanting steadier handling across uneven tracks and rough sections.
The diagonal aperture layout moderates flow to give smooth movement in normal driving while firming up on hard compressions. That combination reduces excessive rebound and improves predictability when landing.
These pistons are intended for big damper use and fit a wide range of shock assemblies. Whether you are setting up for lap time or hard-core bashing, they deliver straightforward improvements with minimal fuss.
