Kyosho IF419-R Right Aluminum Knuckle Arm Gunmetal MP9

This is the right-hand aluminum steering knuckle arm for Kyosho's Inferno MP9, anodized gunmetal.

The knuckle arm is the part the front wheel hub mounts into, and it is what actually steers the car. It carries the steering link, sets the steering axis, and takes every impact the front wheel receives. On a 1/8 scale buggy those impacts are substantial, which is why the aluminum version exists.

Aluminum over the standard part buys you two things. The first is that it does not flex under cornering load, so steering geometry stays where you set it instead of moving around as the car loads up, which makes the front end feel more precise. The second is durability in the impacts that would crack a composite arm outright.

This is the right side only. Left and right knuckles are mirror images and are not interchangeable, so confirm which side you need before ordering. Kyosho also sells the left individually and both together as a pair.

Fitment covers the Inferno MP9, MP9 TKI through TKI4, MP9e and MP9e Evo., MP10, MP10 Spec A, MP10e, MP10e TKI2 and Inferno GT3.
