Suspension arm

Suspension arms are an essential component of individual wheel suspensions in cars and are responsible for wheel guidance. They absorb the lateral forces between the wheel and the vehicle body. Depending on the axle concept, there are many geometric solutions. Suspension arms must withstand high wheel loads and should be resistant to corrosion and very strong. They play a key role in driving mechanics and make a major contribution to safety and comfort.
