An important element of the independent suspension of every car is the lever. It allows providing limited movement directly in the vertical plane of the wheels, holding them in place and not allowing them to roll to the side. According to the design of the suspension, the levers are divided into several types. In each case, holders are used. They provide reliable fixation of the lever at a certain angle. Levers are transverse or longitudinal. They are made of light alloys.

The levers are represented by a cast oblong part equipped with a cylindrical boss. A silent block is inserted into it, or rather pressed into it. This part serves as a gasket when attached to the body, sub frame or frame. The other end is supplied with an annular bead. That serves as a place for fixing the ball joint. Lever designs often vary. It depends on the engineering decisions. In some cases, there is no lug for the ball joint. The product is carried out on the body. The ball joint is attached to the lever with details. In a multi-link rear suspension, levers with cylindrical beads are often used.
