What does the MacPherson strut system integrate into its design?

The MacPherson strut system is a widely used suspension design that integrates a shock absorber and a coil spring into a single assembly. This configuration allows for a compact and efficient suspension system that provides both support and damping for the vehicle.

In this system, the coil spring is positioned around the shock absorber, which allows the strut to absorb road impacts while simultaneously supporting the weight of the vehicle. By combining these two critical components, the MacPherson strut simplifies the suspension layout, contributing to improved handling and better use of available space under the hood. This design also typically allows for easier assembly and can reduce manufacturing costs.

Given this context, the answer indicating that the MacPherson strut system includes both a shock absorber and a coil spring is accurate as it reflects the essential components that work together to provide effective vehicle suspension.
