Stabilizer links transfer weight between the left and right sides of a vehicle. When a vehicle makes a turn, lateral force is applied proportional to the rate of lateral acceleration. Because the center of gravity sits relatively higher than the suspension, this lateral force causes the vehicle to lean away from the direction in which the vehicle is turning. Most commonly you’ll see this in a motor home or large bus, and you may notice the top of the vehicle tilting when it turns a corner.
A stabilizer link transmits some of the lateral force exerted in a turn to the opposite side of the vehicle. This allows the body of the vehicle to stay stable, provides a more comfortable driving experience, and ensures better road handling. Stabilizer links are subjected to extremely high torque loads, and, because of their relatively small size, they will be one of the first parts in the suspension system to require servicing and replacement.
