Kyosho SX056 Front Knuckle Arm Set Scorpion XXL

This is the front knuckle arm set for the Kyosho Scorpion XXL VE.

The knuckle arm is the upright the front wheel hub mounts into, and it is what physically steers the car. It carries the steering link, defines the steering axis, and absorbs every impact the front wheel receives. On a 1/7 scale buggy those impacts are substantial, because the car carries real mass and the wheels are large enough to catch obstacles hard.

Damage here is not always obvious. A knuckle that has been bent rather than broken changes the steering geometry on that side only, which makes the car pull under braking and gives it a different turning radius left versus right. That is a frustrating problem to chase if you have not thought to compare the two sides against each other.

This is the genuine Kyosho part with factory geometry, so fitting it returns the front end to its designed setup rather than approximating it. Note this fits the 1/7 scale Scorpion XXL, not the smaller vintage Scorpion or Turbo Scorpion.
