The Kyosho IFW405-148 SP Shock Piston is a straightforward way to refine damper feel. Made for big dampers, the 1.4mm x 8-hole configuration moderates oil flow so everyday compliance is preserved while compression stiffness rises during hard impacts.
This piston helps maintain chassis balance across different surfaces, giving better control at speed and more predictable behaviour on jumps. The diagonal hole layout is effective at smoothing transition phases without undermining piston strength.
These pistons will fit many larger shock assemblies; verify piston diameter and shock bore match before fitting. Installation is quick, letting you test damping setups and adjust oil weight as required.
