Are front and rear lower arms on MJX Hyper Go 10303 the same geometry?

The front and rear lower swing arms of the MJX Hyper Go 10303 have different specifications and are not interchangeable.
They differ in geometry, mounting hole positions and arm length to suit separate suspension requirements.
The front lower arm works with the C-block and steering knuckle to form caster geometry; its three-hole layout is specially designed for the steered front wheels.
Since the rear wheels do not steer and have no caster angle, the three-point layout of the rear lower arm is built for rear suspension geometry.
The effective arm length, shock mounting point and outer ball stud angle are all different between them. The front arm supports steering movement, while the rear arm provides stable power delivery.
Never swap them. Incorrect fitting will cause binding, wrong camber and poor handling. Always install each arm in its correct position.
