These brass front steering knuckles are intended for Axial SCX24 1/24 scale crawlers and function as a metal hop-up option for the front steering assembly. The set ships with a black finish and is supplied as a direct-replacement component for the model shown in the product title.
The knuckles add mass and stiffness to the front end, which can change steering feel and the vehicle response at low speed and on rough terrain. They are provided as a tuning item for operators wishing to reinforce the front steering mount without changing chassis geometry.
Installation is a direct swap on the SCX24: remove front wheels and hub components, replace the knuckles with the brass set, then reassemble while checking steering travel and alignment before final tightening. Verify orientation during installation since this part is direct-fit for SCX24.
