The Kyosho IFW408B is a hard rear shock stay made to match the MP9 TKI3 chassis. It strengthens the rear suspension mounting and helps M-size shocks remain aligned for cleaner handling through corners and during acceleration.
This shock stay reduces flex at the rear shock tops and supports consistent shock action under load. The improved mounting rigidity helps deliver repeatable handling and reduces unpredictable chassis movement.
The IFW408B is intended for direct fit to the MP9 TKI3 and works with M-size shocks, making it a quick swap for those replacing stock parts or fitting a firmer setup for track work.
