The funktion of stabilizer links, also known as connecting rods
They transmit torsional forces occurring between the body and the chassis to the stabilizer of the particular axle. Depending on the design of the front or rear axle, they form the necessary connection for optimal interplay between wheel guidance and stabilizer. The body roll of the vehicle during cornering is minimized, ensuring safe roadholding.
