The track control arm is an element of an independent vehicle suspension. Serves to provide limited movement in the vertical plane of the wheel, which it holds in place, not allowing it to roll to the side.

Depending on the design of the suspension, the track control arms are divided into types according to the number of attachment points. In addition, they are classified depending on the angle at which they are to the direction of movement of the vehicle.

The construction of the track control arm

The SWAG brand Track Control Arm is an elongated cast light alloy piece with longitudinal stiffeners and lugs at both ends. One end is equipped with a cylindrical bead, into which a silent block is inserted, or rather, pressed in - a part that serves as a gasket when attaching the track control arm to the body, frame or subframe. The second end is provided with an annular bead that serves as a ball joint attachment point. The arm design may vary depending on the suspension engineering solution. For example, there may be no tide under the ball joint, since it is made on the body of the ball joint itself, which is attached to the track control arm with bolts and nuts. In addition, in the rear multi-link suspension, the track control arms with cylindrical beads under the silent block at both ends are often used.
