What is a stabilizer link? A stabilizer link is one of the parts that make up the stabilizer bar/sway bar. The stabilizer bar consists of the bar, links, and bushings. The bar is shaped like a “u”. The bar is attached to the frame of the vehicle with links and bushes. What happens is this system lets the bar flex and in doing so keeps your vehicle on the ground. When you turn your vehicle it creates a force that may create a situation where the vehicle may go up on one side. This system helps to control that.
