The stabilizer bar mounted on the vehicle underbody makes for a more comfortable ride by holding the vehicle itself when the vehicle is cornering. Stabilizer bars are available in two types: solid and tube. To lighten the weight of the vehicle, and owing to weight reduction requirements, tubular stabilizer bars are increasingly being used. Tubular stabilizer bars can be fabricated to be over 34％ lighter than solid bars, but the lifetime of the product tends to decrease rapidly as the weight ratio increases. However, the durability can be improved by utilizing high-strength and high-hardness materials for the stabilizer bar or by improving the shot peening method.
