The MacPherson strut is a common front suspension component in contemporary vehicles. It integrates the shock absorber and coil spring into one unit, reducing both space and weight requirements.
The upper section of this assembly requires robust attachment to manage road-induced forces. It is affixed to a mount or bracket directly connected to the vehicle's structural frame or body. This configuration facilitates the effective transfer of suspension forces to the chassis.
In the MacPherson strut system, elements such as side members, axle pads, or cross members do not specifically serve as this mounting point.
Consequently, the accurate designation for this mounting point is structural frame.
