For example, the link is fixed to the frame and tires bridge,and to pass through the shock absorbing surface of the swing angle so that the positioning of the tires can be controlled within a limited range, but also to play a better shock effect. In addition, it is also mentions different materials and structural reinforcement link designed to achieve weight reduction and high handling.

Normally mounting on shock absorber in the engine room and front/rear bottom. When subjected to a violent car crash side, it will warp from the bends to buff the force and to avoid excessive structural impairment and affect the safety of the driver.

But it doesn't mean that aluminum alloy isn't suitable for making anti-roll bar. A vendor uses 6061 aluminum alloy to create anti-roll bar but coarser diameter must have the same strength than steel anti-roll bar.
